HOW IT WORKS

Connect Webex Calling to the PSTN with Cloud SBC

Epsilon’s Cloud Connect for Webex Calling service uses a cloud-based Session Border Controller (SBC) to establish a secure connection between Webex Calling and your chosen SIP or PSTN provider. As a Certified Calling Provider, Epsilon has completed the certification process for compatibility with Webex Calling, supporting a range of enterprise and service provider deployment requirements. 

The Cloud SBC manages inbound and outbound call traffic between Webex Calling and the PSTN, enabling users to make and receive business calls through Webex Calling while retaining flexibility around existing telephony infrastructure and telephone numbers. Organisations can also use their own SBC where their network architecture or operational requirements call for it.
