Document Overview

Introduction

The interoperability compliance testing focuses on verifying the AT&T IP Toll Free Service together with Sonus SBC 5XXX and CUCM 11 which delivers inbound Voice over IP (VOIP) toll-free calls directly to end-user customer premises. It’s a voice service similar to a traditional toll-free service and allows simultaneous data traffic over a single IP network.

Audience

This technical document is intended for telecommunication engineers with the purpose of configuring the Sonus SBC 5XXX series aspects of the AT&T Toll Free SIP trunk group together with the CUCM 11. Navigating a third-party server and Sonus SBC Web browser user interface, Embedded Management Application (EMA), is required. Understanding the basic concepts for IP/Routing, SIP/RTP and TLS are also required for completing the configuration and any necessary troubleshooting.
