Document Overview

This document provides a configuration guide for Ribbon SBC Core (5000/7000/SWe) series for migrating the Teams' users from Non-Media Bypass to Media Pass.


Introduction

This document is intended for customers planning to migrate from a Non-Media Bypass to a Media Bypass on MS Teams. This document provides configuration steps required on both MS Teams and Ribbon SBC.

Configuration Required On MS Teams

Create a new PSTN gateway on MS Teams

Create a gateway with a different FQDN and SBC listening port number.

Configuration Required on Ribbon Core SBC

 

Create a New Zone and SIP Signaling Port

The new zone can have the same IP address as the previous zone, but not the same port number. If required, change the port number.

Perform one of the following actions:

  • If using a wildcard certificate, attach the previous TLS profile to the SIP Signaling Port.
  • Generate a new certificate and attach it to the SIP Signaling Port.

Create a new Packet Service Profile (PSP)

Enable RTCP Mux for the PSP. This flag is required for the Media bypass.

Code Block
set profiles media packetServiceProfile TEAMS_PSP_MediaBypass
set profiles media packetServiceProfile TEAMS_PSP_MediaBypass codec codecEntry1 G711-default
set profiles media packetServiceProfile TEAMS_PSP_MediaBypass rtcpOptions rtcp enable

set profiles media packetServiceProfile TEAMS_PSP_MediaBypass rtcpOptions rtcpMux enable
commit


Create a new Trunk group

Configure fields for ICE-Lite. This is required for the Media Bypass.

Code Block

Create an IP-Peer for Media Bypass Zone

Enter a globally unique name for the IP Peer.

Code Block
