Webex Edge Audio

A Webex service that routes meeting call-in and callback audio over the enterprise's IP network and Expressway instead of the PSTN.

Definition

With Edge Audio, CUCM routes calls to Webex meetings via SIP over Expressway to the Webex cloud, and callbacks from Webex come back the same way. This reduces PSTN costs and improves audio quality. It depends on CUCM SIP route patterns for webex.com domains and Expressway configuration.

Example

Users dialing the Webex meeting number from desk phones are routed over the internet via Expressway, not the carrier.

Exam tip

Edge Audio is about meeting audio over IP; Edge Connect is about dedicated network peering.
