by a Call Server that is not responsible for the particular zone. Thus,
bandwidth management is not possible for these phones.
Feature packaging
The Adaptive Network Bandwidth Management feature requires the
following packages:
• QoS Enhanced Reporting (PVQM) package 401
Note: Package 401, QoS Enhanced Reporting (PVQM), is required if
the R value from the Phase II IP Phones is to be reported and used in the
calculations.
• Call Admission Control (CAC) package 407
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 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 must 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 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.
