AudioCodes

AudioCodes Ltd. is an Israeli communications technology company that develops software, hardware, and managed services for enterprise communications and telecommunications service providers. Its portfolio is centered on voice connectivity, unified communications, contact centers, voice-network modernization, and artificial-intelligence applications for spoken interactions and workplace collaboration. The company was established in 1993 in Israel by Shabtai Adlersberg and Leon Bialik, who had previously worked at DSP Group. Its early work focused on digital signal processing and voice-compression technology. A significant technical milestone came in 1996, when an AudioCodes voice-compression algorithm became the basis of the ITU-T G.723.1 standard, supporting efficient voice transmission over IP networks. This work helped establish the company in the emerging voice-over-IP market. AudioCodes expanded from component-level voice technology into communications infrastructure, including media gateways, session border controllers, media servers, voice-recording systems, and network-management tools. Through acquisitions and internal development, it broadened its capabilities in service-provider networks, call recording, unified communications, speech recognition, and conversational artificial intelligence. The company’s customers include enterprises, mid-market organizations, telecommunications carriers, managed-service providers, and contact-center operators. AudioCodes states that its technology is used by more than 60 of the world’s 100 largest service providers. The company has maintained a particularly important relationship with Microsoft. Its integrations evolved alongside Microsoft’s unified-communications products, including Office Communications Server, Lync, Skype for Business, and Microsoft Teams. AudioCodes provides certified devices, session border controllers, direct-routing infrastructure, voice-enablement services, and operational tools for organizations adopting Microsoft 365 and Teams. It also supports communications environments involving Zoom, Cisco Webex, Genesys, and other enterprise platforms. Its current portfolio combines physical infrastructure with cloud software and AI applications. Hardware includes the Mediant family of session border controllers, 400HD IP phones, Room Experience meeting-room devices, media gateways, and multi-service business routers. Software and services include the AudioCodes Live platform, One Voice Operations Center, One Voice for Microsoft 365, Meeting Insights, Interaction Insights, VoiceAI Connect, and the Voca Conversational Interaction Center. These offerings address network security and interoperability, meeting transcription and search, interaction recording, conversational bots, contact-center automation, and the management of hybrid voice environments. AudioCodes became publicly traded in 1999 and is listed under the symbol AUDC on both Nasdaq and the Tel Aviv Stock Exchange. Its operations include offices, research and development activities, and support and service teams across North America, Europe, Asia, and Latin America. The company remains led by co-founder Shabtai Adlersberg, who has served as president and chief executive since its inception. Its strategic direction has increasingly emphasized recurring software, managed services, Microsoft Teams voice deployment, contact-center technology, and AI-driven productivity tools.

AudioCodes was founded in Israel in 1993 by Shabtai Adlersberg and Leon Bialik, both formerly associated with DSP Group. The company began with digital signal processing and voice-compression technology at a time when telecommunications networks were beginning to move from circuit-switched infrastructure toward packet-based communications. Its engineering work addressed the technical challenge of carrying intelligible voice over IP networks while using bandwidth efficiently. A major early achievement came in 1996, when an AudioCodes compression algorithm was adopted as the basis for the ITU-T G.723.1 speech-coding standard. This helped validate the company’s technology and gave it visibility in the developing VoIP ecosystem. AudioCodes subsequently moved beyond algorithms and components into complete communications infrastructure, developing media gateways and related products that connected legacy telephony systems with IP networks. The company went public in May 1999, listing on Nasdaq and the Tel Aviv Stock Exchange under AUDC. During the following years, it broadened its service-provider and enterprise portfolio. Acquisitions played an important role in that expansion. In 2003, AudioCodes acquired Nortel Networks’ Universal Audio Server product group. In 2004, it purchased Ai-Logix, adding voice-recording hardware and call-logging capabilities. In 2006, it completed the acquisition of Nuera Communications, a broadband-telephony media-gateway provider, and acquired Netrake, whose products focused on session border controllers and security gateways. CTI Squared was acquired in 2007 to add unified-communications platform capabilities. AudioCodes continued investing in application-layer communications. Its 2010 acquisition of Natural Speech Communication added speech-recognition expertise, while the 2013 acquisition of MailVision expanded its VoIP and unified-communications capabilities. These developments reflected the industry’s shift from standalone network equipment toward integrated voice applications, communications management, and software-defined services. A central strategic development was AudioCodes’ relationship with Microsoft. The company supported Microsoft’s enterprise communications platforms as they progressed from Office Communications Server to Lync, Skype for Business, and Microsoft Teams. AudioCodes developed certified voice endpoints, session border controllers, direct-routing solutions, operational-management tools, and implementation services for Microsoft environments. This positioned the company as an interoperability and voice-modernization specialist for organizations adopting Microsoft 365 while retaining carrier services, premises equipment, or existing telephony systems. The pandemic period accelerated hybrid work and increased the importance of cloud-based collaboration. AudioCodes responded by emphasizing managed solutions, Teams voice deployment, cloud service delivery, and applications that could improve meeting and contact-center productivity. The company also expanded its use of artificial intelligence in transcription, speech recognition, interaction analytics, conversational bots, and meeting intelligence. Its acquisition of Callverso in 2021 strengthened its conversational-AI and natural-language-understanding capabilities. AudioCodes’ portfolio now spans hardware, software, cloud platforms, and professional or managed services. Mediant session border controllers support SIP trunking and Microsoft Teams Direct Routing in on-premises and cloud deployments. The company’s 400HD phones and Room Experience devices provide certified business and meeting-room endpoints. Media gateways and multi-service business routers connect legacy and IP-based networks. On the software side, AudioCodes Live provides a multi-tenant service-delivery platform; Meeting Insights captures and organizes meeting content; Interaction Insights supports recording and compliance use cases; VoiceAI Connect links conversational bots with telephony and speech services; and Voca provides an AI-enabled contact-center environment. AudioCodes remains headquartered in Or Yehuda, Israel, with international offices, research and development operations, and support teams across North America, Europe, Asia, and Latin America. It serves enterprises, mid-market organizations, carriers, managed-service providers, and contact centers. The company continues to be led by co-founder Shabtai Adlersberg as president and chief executive, with its strategy focused on secure voice connectivity, unified communications, Microsoft Teams, contact-center modernization, and AI-supported workplace and customer interactions.
