Bring Your Own PSTN Solution
The Bring Your Own PSTN (BYoPSTN) solution lets Webex for Cisco BroadWorks Service Providers provision phone numbers that they own for users to use when joining Webex Meetings. The solution lets Partners leverage their own PSTN networks and make use of existing relationships with PSTN providers, rather than using Cisco-provided numbers.
The reference architecture in this document provides an end-to-end design for the BYoPSTN option. This architecture is validated by Cisco and uses Cisco Unified Border Element (CUBE) as the Session Border Controller (SBC) for call traffic between BroadWorks and Webex Meetings.
