Meet the Team

We are the Unified Communications (UC) Software Development team within Cisco Routing Business Unit under the Workplace Technology Group. Our team is responsible for a wide range of voice solutions, including Cisco flagship Voice Gateways (VG) for both Cloud Calling and On-Prem Calling, Digital Signal Processors (DSP) modules, as well as Analog and Digital Voice Modules operating on Catalyst 8200/8300 routing platforms. We also develop VoIP applications such as audio conferencing, transcoding, SWMTP, Fax, and Secure Modem for DoD and DoJ, and Secure Voice (TLS and sRTP).

Our mission is to develop and maintain a competitive and high-quality VG and VoIP products, support the transition from on-prem to cloud calling, and integrate key UC capabilities into Cisco SD-WAN.
