Region Configuration
Use regions to specify the bandwidth that is used for audio and video calls within a region and betw ee n
existing regions. Use the following procedures to add, update, or delete regions, and to synchronize
configuration changes with affected devices:
• Region Configuration Settings, page 8-1
• Finding a Region, page 8-4
• Configuring a Region, page 8-5
• Synchronizing a Region With Affected Devices, page 8-9
• Deleting a Region, page 8-9
• Related Topics, page 8-10
Refer to the “Regions” section in the Cisco Unified Communications Manager System Guide for more
information about configuring regions and selecting audio codecs.

Region Configuration Settings

Use regions to specify the bandwidth that is used for audio and video calls within a region and betw ee n
existing regions.
• The audio codec determines the type of compression and the maximum amount of bandwidth that is
used per audio call.
• The video call bandwidth comprises the sum of the audio bandwidth and video bandwidth but does
not include overhead.
Note The default audio codec for all calls through Cisco Unified Co mmunications Manager specifies G.711.
If you do not plan to use any other audio codec, you do not need to use regions. Se e the “Related Topics”
section on page 8-10 for more information.
Cisco Unified Communications Manager supports up to 2000 regions. The foll owing limi tati ons and
restrictions apply:
• Configure as many regions as possible to Use System Default for inter-/intra-region audio codecs
and video bandwidth.
• This enhancement requires an MCS 7845H1 or higher server.
