3. Configure the Avaya Media Server and Media Gateway
The configuration of the Avaya Media Server and Media Gateway should follow the standard
Avaya recommendations for IP Telephony [1]. In general a Quality of Service (QoS) policy
must be established across the entire IP network. The Differentiated Services (DiffServ) Code
Point (DSCP) values used by Avaya Communication Manager and by the FS726TP must be the
same.
From the System Access Terminal (SAT) enter the change ip-network-region command with
the appropriate region number specified to open an IP Network Region configuration screen. Set
the QoS DiffServ/TOS and 802.1P/Q parameters highlighted below. These are the defaults,
normally no changes will be needed.
