Region Configuration
Use regions to specify the voice codec used for calls within a region and between existing regions. The voice codec determines the type of compression and maximum amount of bandwidth used per call.
Note
The default voice codec for all calls through Cisco CallManager is G.711. If you do not plan to use any other voice codec, you do not need to use regions.
Use the following procedures to add, update, or delete regions:
•
Refer to the "Regions" section in the Cisco CallManager System Guide for more information about configuring regions and selecting voice codecs.
Adding a Region
This section describes how to add a new region to the Cisco CallManager database.
Procedure
Step 1
Step 2
Step 3
See Table 7-1 for a summary of the available codec types and bandwidth usage.
Before saving the changes, you can click Cancel Changes to reset all fields to original values.
Step 4
Next Step
After adding a new region to the database, you can use it to configure device pools. Devices acquire a region setting from the device pool to which they are assigned. See the "Adding a Device Pool" section for information on configuring device pools.

Region Configuration Settings
Table 7-1 summarizes the available voice codecs that can be specified for regions. The total bandwidth used per call depends on the voice codec type as well as factors such as data packet size and overhead (packet header size). The bandwidth figures shown in Table 7-1 apply for 30-ms data packets and include IP headers.
