Webex Edge Audio is a solution that optimizes audio calls for organizations with Cisco Unified Communications Manager or Cisco Business Edition (formerly Cisco HCS). It offers cost reduction and enhanced audio quality by intelligently routing calls through the enterprise network and Webex Edge Connect directly to the Webex cloud, bypassing the public switched telephone network (PSTN).
Key Features:
- PSTN Cost Savings and Enhanced Audio Quality: Calls are intelligently routed through the enterprise network and Webex Edge Connect, providing a simpler path for audio, improving quality, and reducing PSTN costs.
- Simple Deployment and No User Behavior Change: Participants can join Webex meetings seamlessly, either via a direct VoIP route to the Webex cloud or using their existing PSTN services, without any changes in behavior.
- Flexibility: The solution offers on-network deployment in locations where PSTN savings can be achieved, and off-network minutes can be purchased for other locations without an on-premises or Unified CM deployment.
- Compatibility: It is compatible with various deployment models and versions of Unified CM and Expressway as outlined in the Webex configuration guides.
- Security: It utilizes signed certificates from trusted certificate authorities for secure connections, with support for TLS and mutual TLS (mTLS) for secure Real-time Transport Protocol (SRTP).
- Lua Scripting: Edge Audio employs Lua scripts for configuration, normalization, and custom dial-in number support, enabling site-specific customization of the service.
