Configuring IP network regions
An IP address map can be used for network region assignment. The network region
assignment can be used to vary behaviors within and between regions. Typically, though this
can be varied, each location will match an IP region and vice versa.
The following screen illustrates a subset of the IP network map used for this example
configuration. Branch 811 has IP addresses in 192.168.42.0/24 assigned to network region
11.
The following screens illustrate important aspects of the settings for each IP Network Region.
The IP Network Region for each branch is mapped to the matching location . The values used
for Branch 812 in IP Network Region 12 are shown below.
• The Authoritative Domain matches the SIP domain configured in the Avaya
Aura
®
Session Manager and the B5800 Branch Gateway.
• The Codec Set for intra-region calls is set to the codec set created for SIP calls.
• The Intra region IP-IP Direct Audio and Inter region IP-IP Direct Audio parameters
are set to yes to allow direct media paths within and between regions. This minimizes the
use of media resources in the Media Gateway.
The connectivity between network regions is specified under the Inter Network Region
Connection Management heading, beginning on Page 3. Codec set 1 is specified for
connections between network region 11 and network region 1.
