Adaptive Network Bandwidth Management 77
Configuration rules
The configuration rules for Adaptive Network Bandwidth Management are
as follows:
• Each main office Call Server in a network must have a unique non-zero
VPNI.
• All branch offices(MG1000B or SRG) associated with a particular main
office must have the same VPNI as the main office Call Server.
• All IP Phones (other than specific IP SoftPhone 2050s) and DSP
endpoints on a Call Server must be configured for the same zone.
• IP SoftPhone 2050s being used remotely must be configured for Zone 0.
• Branch Office systems(MG 1000B or SRG) should tandem all calls
through the main office Call Server to allow bandwidth monitoring and
control. In this case, the media path is direct between the Branch Office
and any point in the network.
• Trunk Route Optimization (TRO) must be disabled between the main
office Call Server and the MG 1000B Core or SRG. In this case, the
media path is direct between the Branch Office and any point in the
network.
• Adaptive Network Bandwidth Management parameters are configured
on the main office only and must not be configured at the branch offices.

d. Configure the interzone and intrazone bandwidth limits at the main
office and MG 1000B Core or SRG.
e. Enable Adaptive Network Bandwidth Management for the zones
on the main office Call Server.
f. If required, alter the Adaptive Network Bandwidth Management
parameters in keeping with the information in "
"Advanced
Configuration Notes" (page 78) " below.
3. Tandem the outbound Branch Office calls by configuring the NRS.
