PART I

Item 1. Business

Overview

        We develop software and hardware platforms that original equipment manufacturers, or OEMs, developers, network operators and corporate information technology managers build into their communications systems. Customers incorporate our products into applications, systems and services that allow voice, fax and data to be distributed over both Internet protocol, or IP, packet-based networks, which we refer to as the New Network, and the traditional circuit-switched telephone network. We supply products for media processing, network interface, call control and signal processing, including protocols that allow Internet and traditional telephony systems to communicate. Our strategy is to partner with our customers and collaborate closely with them to accelerate their delivery of new applications and services, help increase their existing business, and expand into new markets.

        In the 1980s, we delivered technology capable of digitally recording, storing and playing voice messages using a computer connected to the telephone. In the 1990s, we introduced multi-channel fax boards, combined fax and voice processing on a single board, and provided fax application development tools under UNIX and Microsoft Windows NT. We also received U.S. patents relating to fax-on-demand document retrieval and the use of direct inward dialing telephone service with fax message systems. Since 2000, we have introduced new, open systems products in support of market growth areas such as Voice over IP, or VoIP, automatic speech recognition, and unified communications, and have received a U.S. patent relating to voice detection in audio signals to aid in speech recognition applications. In April 2004, we completed our acquisition of all of the outstanding capital stock of SnowShore Networks, Inc., or SnowShore, a provider of Voice over IP communications infrastructure products for the media server market.

        The evolution of the world's communications systems has resulted in the convergence of the traditional telephone network and the IP network. This converged communication system—which we call the New Network—has created important market opportunities for us. Effective electronic communication over the New Network depends upon network infrastructure technology that weaves together the many existing, disparate systems and applications with new and emerging technologies. We develop the core technology that connects the telephone network to the data network in three key markets: fax, enterprise voice and carrier enhanced services. Network interfaces, call control and signal processing are critical to the proper functioning of any communications system. These capabilities span our entire product line and provide the intelligence by which telephone calls are established, managed and terminated.

        We were incorporated in Massachusetts in 1984 and we changed our name from Brooktrout Technology, Inc. to Brooktrout, Inc. in 1999. We maintain a website with the address www.brooktrout.com. We are not including the information contained on our website as a part of, or incorporating it by reference into, this report. We make available free of charge through our website our annual reports on Form 10-K, quarterly reports on Form 10-Q and current reports on Form 8-K, and amendments to those reports, as soon as reasonably practicable after we electronically file them with the SEC. Please see our financial statements included in Item 8, "Financial Statements and Supplementary Data," for information about our operating results and financial condition, including information as to our revenues, net income (loss) and total assets.

Principal Markets and Products

Markets

        Our products provide enabling technology in three key markets—fax, enterprise voice and carrier enhanced services.

1

Fax

        Fax refers to multi-user, computer-based fax systems that are deployed by enterprises and service providers to streamline business processes, enhance worker productivity, and offer sophisticated faxing capabilities to small-office and home-office based individuals. These systems, usually called fax servers, are capable of communicating with traditional fax machines, and with computer networks and applications. Fax servers using our enabling technology also include specialized software offered by our customers. In office environments, fax servers allow workers to send fax documents directly from their originating desktop applications, and to receive faxes through their e-mail inbox. Fax servers can also integrate directly with business applications to automatically generate faxes of documents such as purchase orders, financial trade confirmations, and patient medical records. Service providers use fax servers to offer outsourced high-volume faxing capability to corporations, or Internet-based "virtual fax machines" to individuals.

        Faxing is a traditional form of communication, but several factors combine to spur demand for multi-user computer-based fax systems in which Brooktrout's products are used. Business regulations such as the Health Insurance Portability and Accountability Act of 1996, or HIPAA, and the Sarbanes-Oxley Act of 2002, or Sarbanes-Oxley, have expanded the need for secure, verifiable communications. When faxing is the preferred method of communication, computer-based fax systems are capable of maintaining a permanent, searchable record of content, destinations, as well as faxes sent and received. Faxing is a component of business process automation and document management systems. As a result, upgrades of these essential business systems often result in purchases of related fax board servers. New technologies and standards are also creating demand for new fax systems to replace the installed base. The transition of many company voice networks to VoIP requires migration to IP-connected fax systems that comply with the T.38 fax over IP standard. Also, companies are replacing older low-speed fax systems with newer high-speed V.34-capable equipment. The popularity of Internet e-mail has also created a market for fax-to-email or Internet fax services that rely on computer-based fax systems.

        We believe we are the worldwide market leader of intelligent fax boards. The market for fax technology is growing due to continued e-mail usage and the desire to connect faxes with e-mail. We offer open, scalable platforms to independent software vendors and fax application system developers. Our platforms integrate with e-mail, enterprise resource planning, customer relationship management, document management and imaging applications.

Enterprise Voice

        The enterprise voice market consists of voice and telephony-related applications that enterprises use to conduct business processes and/or enhance worker productivity. These applications include interactive voice response, or IVR, and automatic speech recognition, or ASR, systems that perform information retrieval, transactions, and call routing using human speech or touch-tone inputs. Other examples of enterprise voice applications are voice mail, unified messaging, and call recording.

        Our opportunity in enterprise voice is tracking with several powerful business strategies and technological trends. Businesses are looking for ways to reduce operational expenses while improving customer service through speech automation. They also want to leverage significant web infrastructure investments by making the same information and applications accessible to telephone users. Traditional touch-tone systems have been constrained in achieving these goals due to their limited user interface and the difficulty integrating them with other back-end business data and applications.

        Recent technology improvements in ASR allow for a more natural and flexible user interface. New application development standards, such as VoiceXML and SALT, allow voice applications to be created as extensions to existing web-based applications. As a result, enterprise voice applications are expanding from the domain of specialized IVR vendors to that of mainstream information technology

2

leaders. Microsoft's Speech Server is an example of this, and has the potential to move voice into a broader array of business applications.

        As with fax, the migration to VoIP also generates the need for new voice application systems that connect to VoIP networks. As a provider of open systems enabling technology, we offer products that are components of an overall solution. We work with our partners to provide enterprise customers with quality voice and speech solutions. We continue to work closely with the leading providers of speech technology and development tools to help ensure interoperability and optimal performance so that applications developed using our products can be accomplished with ease and deployed with confidence.

Carrier Enhanced Services

        Carrier enhanced services are voice and telephony-related applications and services that telecommunications carriers provide to increase their revenues or enhance their competitiveness within the market. This evolving market is characterized by the transformation of telephone and cable companies into providers of comprehensive telecommunication services as they expand their traditional service offerings. Telephone companies are now providing broadband internet and cable television services while traditional cable companies are offering customers voice-related services. Applications spurring growth in the carrier enhanced services market include voice and video mail, video content, ringback tones, prepaid services, IP Centrex, and conferencing. These services may be deployed in the traditional public switched telephone network, or PSTN, or in next-generation networks such as VoIP, 3G wireless, and broadband.

        Carriers are now migrating their infrastructures toward IP-based technologies. Within these networks, carriers need to deploy enhanced services as a way to increase average revenue per user in the face of price erosion for basic telephone connectivity. A recent example of this, using our products, was the introduction of video mail and sports highlights for mobile phone users by TMN, Portugal's leading mobile operator.

        Enhanced services are of such importance that the Third Generation Partnership Project, or 3GPP, a consortium of European telecommunications organizations, has specified a standard architecture known as the IP Multimedia Subsystem, or IMS, specifically for delivering enhanced services in next generation mobile networks. 3GPP's counterpart in North America and Asia, 3GPP2, has also adopted the IMS architecture. Fixed broadband cable and DSL telephony service providers are also using an IP-based infrastructure for enhanced services that is modeled after IMS or is IMS-like. Most major network equipment vendors now offer or plan to offer an IMS-based product set. Media servers, such as Brooktrout's SnowShore Media Server, are key components of IMS and IMS-like systems.

        The enhanced services market is characterized by a move toward industry standard protocols such as SIP, VoiceXML and MSCML, supporting next generation IP environments such as 3G wireless and broadband. This trend toward standardized architecture and protocols within carrier networks fuels general demand for next-generation equipment. It also allows us to effectively leverage a standard product—the media server—across a wide range of customers, in contrast with prior industry practices that often called for customization for each major OEM customer.

New Products; Research and Development

        Our continuing development efforts are focused on software and hardware for traditional telephone networks, or TDM, and IP media processing products (voice, video, fax, and data), network interface products, call control products, and signal processing products.

        The market for communications products is generally characterized by rapid technological change, changes in customer requirements, frequent new product introductions and enhancements, and emerging industry standards. We focus significant resources on improving our products in response to changes in operating systems, application software, computer and telephony hardware, networking software, programming tools, and computer language technology. We also direct significant resources to the development of new products and next generation versions of our current products. As technologies continue to evolve, there has also been a growing shift in the communications market to focus on the software component of our product offerings. While we have delivered both hardware and software as part of our product line since our company began, we are beginning to emphasize the value of our software for our customers and partners. Our research and development expenses totaled $18.1 million, or 23% of total revenue, in 2004; $18.5 million, or 25% of total revenue, in 2003; and $20.7 million, or 28% of total revenue, in 2002. We believe that significant investments in product development are required to remain competitive. As a consequence, we intend to continue to invest significant resources to product development.

Warranties

        Our hardware products are covered by a limited warranty against defects in materials and workmanship. Our generally available network interface and fax and voice signal processing hardware products have warranties of five years from the date of purchase from us. Many of our competitors have shorter warranties for this type of product. Our SnowShore Media Server hardware products are covered by a one-year warranty. We have also provided, from time-to-time, shorter warranties for certain products and to certain customers, as well as extended warranties to certain customers under contractual agreements or for additional consideration.

Backlog

        At December 31, 2004, our backlog of firm orders was $3.9 million, compared with $4.1 million at December 31, 2003. All of the backlog is expected to be shipped before the end of 2005. We regard all orders as firm orders. Because of the possibility of customer changes in delivery schedules or of cancellation of orders, our backlog as of any particular date may not be indicative of actual sales for any particular future period. The period of time between placement of an order and delivery of the product varies from one week for certain value-added resellers, or VARs, and enterprise customers to twelve months for certain OEM systems products.

Manufacturing and Quality

        Our manufacturing operations consist primarily of final assembly and testing of components, subsystems, and systems. We test our products at various stages in the manufacturing process. Prior to shipment, each product undergoes a final load and/or functional test either by our subcontractors or by us at our own facilities.

        We believe that we have a readily available supply of raw materials for all of our significant products from a number of sources. We do not anticipate any difficulties in obtaining the raw materials that will be required for our manufacturing activities in 2005. We use independent manufacturers to perform printed circuit board assembly and testing. We believe that we generally have good relationships with our subcontractors and have generally experienced timely delivery of products and satisfactory quality with respect to products manufactured by our subcontractors. Our Needham,

6

Massachusetts, Los Gatos, California, and Salem, New Hampshire facilities have achieved ISO 9001:2000 certification.

Distribution, Sales, Marketing and Support

        We sell our products to system vendors, service providers, OEMs, and VARs, both domestically and internationally through a direct sales force and a two-tiered distribution system. The two-tiered distribution arrangement is with Tech Data Corporation, a networking supplier, and Ingram Micro, a wholesale distributor of computer technology products and services.

        We have established international sales offices in Belgium, Canada, Japan and the United Kingdom. International sales accounted for approximately 20% of our total revenue in 2004 and 22% of our total revenue in both 2003 and 2002. Refer to Note 14, "Segment Reporting," to the consolidated financial statements under Item 8 of this report.

        Most countries require technical approvals from their communications regulatory agencies for products that operate in conjunction with the local telephone system. Obtaining these approvals is generally a prerequisite for sales in a given jurisdiction. Obtaining the requisite approvals may require from two months to a year or more depending on the product and the jurisdiction. Our products have received approvals from agencies in forty countries.

        We ordinarily sell our products on the basis of purchase orders received from customers. From time-to-time, we have entered into contracts with certain of our customers, which agreements set forth the terms and conditions for sales. These agreements generally do not establish any long-term fixed purchase or supply commitments for either party.

Service Providers and OEMs

        Service providers of enhanced communications services develop, or purchase from developers, large, complex systems incorporating our products to deliver electronic communications applications. These systems typically have long development cycles and result in periodic deployments of large systems. OEMs design, manufacture, and market electronic communications systems that incorporate our products. OEMs generally have long product design and development processes that precede the release of products. Making sales to both of these types of customers can be a complex and time-consuming process that is often focused on technical requirements.

VARs and Enterprise Customers

        VARs typically purchase our products for resale to an end-user enterprise customer together with application software developed by the VAR or purchased from an independent software vendor. We have established a network of authorized resellers. We employ direct sales people to recruit, train and assist VARs. We also use a two-tiered distribution system for some of our fax, voice and network interface products, utilizing national distributors who then sell to VARs. In the two-tiered distribution system, we do not recognize revenue until the products are sold by the distributor.

Dependency on Major Customers

        Sales to Captaris, Inc. represented 18% of our total revenue in 2004, 19% of our total revenue in 2003, and 15% of our total revenue in 2002. No other customers represented more than 10% of our total revenue in 2004, 2003 or 2002.

Partner Access Network Program

        Our Partner Access Network Program was established to provide technical, marketing, and business benefits to help our customers and partners quickly develop new applications and services,

7

expand into new markets and, ultimately, grow their businesses. The program includes access to lab facilities worldwide, sales leads, technical training and support, and co-op funded marketing support.

Technical Support

        We back our products with engineering-level support. Many of our technical support staff members hold bachelor's degrees in electrical engineering or computer science. Staff members place the highest priority on providing timely, accurate information, as well as advice on how to take advantage of our sophisticated product line. Our technical support personnel have been a source of product improvements and new features and functions resulting from their close working relationships with customers. Our technical support activities represent an integral element of our marketing strategy.

Patents, Licenses and Trademarks

        We depend on our ability to develop and maintain the proprietary aspects of our technology. To protect our proprietary technology, we rely primarily on a combination of contractual provisions, confidentiality procedures, trade secrets, and patent, copyright and trademark laws.

        From time-to-time, we seek patent protection for inventions and developments made by our personnel that are incorporated into our products or that otherwise fall within our fields of interest. For example, in 2001, we were awarded a U.S. patent for voice detection in audio signals, which aids in speech recognition applications. While patents are an important means by which we seek to protect our intellectual property, no particular patent, or related group of patents, is so important that its loss would significantly affect our operations.

        We have acquired licenses under certain third-party patents covering aspects of voice processing and voice transcoding technology, and licenses from third parties for some of the software used in certain of our voice and fax products. We pay royalties under these licenses with respect to our sales of certain products. The licenses generally extend for the life of the patent in question (in the case of patents) or in perpetuity (in the case of software), and are subject to termination only in the event of a breach. Royalties constitute a percentage of sales of particular products or product elements, or a fixed amount per unit of hardware or software distributed, and do not generally account for a material part of our cost of product sold.

        We seek to protect our software, firmware, documentation, and other written materials under copyright laws. Because on-board and downloadable firmware represents an important element of the value of our hardware products, we believe that we obtain significant protection for our proprietary interest in our hardware products, as well as our software products, from copyright laws. Certain design features, including application-specific integrated circuits, software and firmware, receive some protection under trade secret laws. We generally require that each of our employees execute a proprietary information agreement designed to protect our trade secrets, inventions created in the course of employment with us and other proprietary information. There can be no assurance, however, that patent, copyright and trade secret protection will be sufficient to prevent competitors from developing software and other technology similar to the software and other technology upon which we rely for a significant portion of our revenue. In addition, we have periodically received, and may receive in the future, communications from third parties asserting patent rights with respect to certain of our products and features.

Competition

        The market for telecommunications equipment is highly competitive. In addition to current competitors, there is always the potential for new entrants into our markets by other companies, including our customers and suppliers. We believe that the principal competitive factors affecting the market for our products include product functionality and features, product quality, performance and

8

price, ease of product integration, and quality of customer support services. In addition, many of our customers and partners, including the large OEMs on whom we focus a significant portion of our sales and marketing efforts, have the technical and financial ability to design and produce components replicating or improving on the functionality of most of our products. These customers often consider in-house development of technologies and products as an alternative to doing business with us, and the emergence of outsourcing and open source software provides additional competition as customers may determine to outsource or use open source technology instead of purchasing our products. The relative importance of each of these factors depends upon the specific customer environment. Although we believe that our products currently compete favorably with respect to such factors, there can be no assurance that we can maintain our competitive position against current and potential competitors.

        Brooktrout faces intense competition within each of our chosen market segments—fax, enterprise voice, and carrier enhanced services. Within the fax market, our competitors are typically manufacturers of fax platforms. Here, we believe we are able to compete successfully with these vendors due to our established market leadership, our comprehensive product offerings, scalability, focus on product quality and commitment to partnership. Competitors in the enterprise voice space are typically manufacturers of voice platforms as well as solution providers of speech and voice based systems. We believe we compete successfully in this space based on our product scalability, quality and commitment to partnership. Within the carrier enhanced services market, our competition consists of enabling technology providers of communication based platforms and systems as well as service providers or carriers intent on developing products like ours internally. Here, we believe we compete successfully due to our comprehensive, open architecture, software-based functionality, performance, and commitment to partnership.

        Many of our current and potential competitors have longer operating histories, significantly greater financial, technical, product development and marketing resources, greater name recognition, and larger customer bases than we do. Though our addressable market in the overall telecommunications market is characterized by several large competitors, the rest of the market is fairly fragmented and many of our current and potential competitors are smaller companies. These smaller companies generally have significantly less financial, technical, product development and marketing resources, lesser name recognition and smaller customer bases, but these smaller companies may also have an ability to respond more quickly to changes in the market or technology. Our present or future competitors may be able to develop products comparable or superior to those developed by us, adapt more quickly to new technologies, evolving industry trends or customer requirements, or devote greater resources to the development, promotion and licensing of their products than we can. Accordingly, there can be no assurance that competition will not intensify or that we will be able to compete effectively in our market.

        We have faced, and we expect that we will continue to face, increasing pricing pressures from our current competitors and new market entrants. Our competitors may engage in pricing practices that cause us to reduce the selling prices of our products. To offset declining selling prices, we believe that we must successfully develop and introduce, on a timely basis, new products or products that incorporate new features that can be sold at gross profits comparable to those of existing products. To the extent that such new products are not developed in a timely manner, do not achieve customer acceptance, or do not generate comparable gross profits, our profitability may decline.

Employees

        As of December 31, 2004, we had 308 full-time employees, of whom 110 were engaged in engineering and product development, 110 in sales, marketing and technical support, 53 in administration, and 35 in manufacturing. None of our employees are represented by a labor union and we believe our relationships with our employees are good.

Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations

        The following discussion should be read in conjunction with the consolidated financial statements and related notes in Item 8 of this report. The discussion contains forward-looking statements that involve known and unknown risks and uncertainties, including those set forth below under "Factors That May Affect Future Results."

Overview

        We develop software and hardware platforms that OEMs, developers, network operators and corporate information technology managers build into their communications systems. Customers incorporate our products into applications, systems and services that allow voice, fax and data to be distributed over both IP packet-based networks, which we refer to as the New Network, and the traditional circuit-switched telephone network. We supply products for media processing, network interface, call control and signal processing, including protocols that allow Internet and traditional telephony systems to communicate. Our strategy is to partner with our customers and collaborate closely with them to accelerate their delivery of new applications and services to end-users, help increase their existing business, and expand into new markets. In April 2004, we completed our acquisition of all of the outstanding capital stock of SnowShore Networks, Inc., or SnowShore, a provider of Voice over IP communications infrastructure products for the media server market.

        We measure our operating success using both financial and market metrics. The financial metrics include revenue, gross profit, operating expenses, operating income and net income, as well as working capital and cash flows from operating activities. Key market metrics include the total number of customers, customers whose purchases exceed $100,000, and the portion of our revenue that is generated by the sales of products to enterprise and service provider customers. Our long-term business model stresses our commitment to establishing and maintaining close customer relationships, increasing penetration of the telecommunications markets that we serve and continuing to develop innovative products.

        The most significant trend that has impacted our business during the past few years has been the unfavorable economic conditions affecting the communications sector. During the past few years we continued to invest in developing products that we believe our customers will need when the economy recovers. We are now seeing signs that the economic conditions in our industry may be improving with modest revenue growth from 2002 to 2003 and further growth from 2003 to 2004. Many companies that had reduced their capital expenditures during the recent economic downturn have begun to invest again in their communications networks. The evolution and acceptance of the New Network is contributing to these infrastructure investments as enterprises and service providers begin to use the IP networks for fax and Voice over IP transmissions. The signs that the economic conditions in our industry are improving lead us to expect that revenue for each quarter of 2005 will exceed the revenue for each corresponding quarter of 2004.

Application of Critical Accounting Policies

        Management's discussion and analysis of financial condition and results of operations is based upon our consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States of America. We make estimates and assumptions in the preparation of the consolidated financial statements that affect the reported amounts of assets and liabilities, revenue and expenses, and the related disclosures of contingent assets and liabilities. These estimates form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. We base our estimates and judgments on historical experience and on various other assumptions that we believe are reasonable under the circumstances. However, actual results may differ from these estimates under different assumptions or conditions.

14

        The following critical accounting policies require the use of significant judgment and estimates in the preparation of the consolidated financial statements. This listing is not a comprehensive list of all of our significant accounting policies. For further information regarding the application of these and other accounting policies, see Note 1, "Description of Business and Summary of Significant Accounting Policies and Practices," to the consolidated financial statements in Item 8 of this report.

Revenue Recognition

        Revenue from product sales is recognized when the risk of loss and title pass to the customer, generally at the time of shipment, provided that persuasive evidence of an arrangement exists, the fee is fixed or determinable, and collection is reasonably assured. To the extent that one or more of these criteria are not met, which has occurred from time-to-time, revenue is deferred until such time as all four criteria are met. Revenue from sales to certain distributors is recognized on a "sell-through" basis, that is, when the distributors report to us that resale of the product to the ultimate customer of the distributor has occurred. If we receive a payment from a customer prior to meeting all of the revenue recognition criteria, the payment is recorded as a customer deposit or deferred revenue. In addition, customers are offered the option to enter into maintenance contracts on selected products that are renewable. Prepaid maintenance fees on these contracts are deferred and recognized evenly over the term of the maintenance contract.

        We record a provision for estimated sales returns and allowances on product sales in the same period that the related revenue is recorded. These estimates are based on historical sales returns, analysis of credit memo data and other known factors. We periodically offer rebate programs to customers that require us to estimate the cost of the program. We record a provision for the estimated cost of the program as a deduction from sales based on the results of previous rebate programs and other known factors.

Allowances for Doubtful Accounts

        Accounts receivable are reduced by an allowance for amounts that may become uncollectible in the future. The estimated allowance for doubtful accounts is based primarily on a specific analysis of accounts in the receivable portfolio and a general reserve based on the aging of receivables. While management believes the allowance to be adequate, if the financial condition of our customers were to change or deteriorate, resulting in an impairment of their ability to make payments, additional allowances may be required and could materially impact our financial position and results of operations.

Inventory Allowances

        We evaluate our inventories for estimated excess quantities and obsolescence. This evaluation includes analyses of sales levels by product and projections of anticipated future demand. In addition, we assess the impact of changing technology on our inventory. We provide reserves for inventories that are considered excess or obsolete. If future demand or market conditions are different than our projections, additional inventory reserves may be required and would be reflected in cost of sales in the period in which the revision is made. If future demand or market conditions are more favorable and products for which reserves have been provided become more marketable and are sold, our gross profit could improve. These actions could impact both our results of operations and our cash flows.

Intangible Assets

        We review our intangible assets for impairment periodically and whenever events or changes in circumstances indicate that the carrying value may not be recoverable. The evaluation of the recoverability of our intangible assets includes assumptions regarding estimated future undiscounted

15

cash flows associated with these assets and other factors. If these estimates or assumptions change in the future, we may be required to record impairment charges for these assets. Such an impairment charge would impact the results of operations, but would not directly impact our
