Cisco Webex Edge Audio for the Cisco Unified Border Element
Cisco enhances the Webex audio experience, saving PSTN costs and scaling to handle any call load into the Webex Cloud.
Cisco has had Webex Edge Audio for Expressway for some time now. The concept behind Edge Audio is to provide an alternate path for Webex audio calls, diverting them from potentially overtaxed public switched telephone network (PSTN) connections to the internet. Now, Cisco provides an additional method to take advantage of Edge Audio via the Cisco Unified Border Element (CUBE).
Edge Audio for CUBE was released for Webex in Q3 2020. It is an audio solution where Webex calls originating within your enterprise route from your Cisco Unified Communications Manager (CUCM)/PBX to CUBE, over the internet, and into the Webex cloud. Similarly, callbacks initiated by Webex users are routed from the Webex Cloud, traverse the internet, leverage CUBE infrastructure, and are delivered onto your CUCM/PBX for on-net routing. This can greatly reduce PSTN loads and expenses, offloading that traffic to leverage internet bandwidth instead.
