In Cisco Unified Communications Manager, where do you configure the default bit rate for audio and video devices?
A. Enterprise Parameters
B. Region under Region Information
C. Cisco CallManager service under Service Parameter Configuration
D. Enterprise Phone Configuration
The Answer is C.
Regions is where you configure preference list and the MAXIMUM bit rate.
You do not configure the default bit rate in regions.
That is as Ken has said, under the Service Parameters.
The answer is correct, it should be C. Go to Service Parameters>CUCM>Cisco Call Manager>Clusterwide Parameters (System – Location and Region).
Maybe option B
For each region that is specified in the Regions window pane, choose the value from the drop-down list box in this column to set the maximum bit rate to use for audio between this region and the specified region. This setting applies to both audio and video calls and serves as an upper limit for the audio bit rate, which means that audio codecs with higher bit rates than the one that you specify are not used for these calls.
For example, if you choose 64 kbps (G.722, G.711), G.722 or G.711 may get negotiated for the calls because both codecs use 64 kb/s. G.722 has better audio quality than G.711, so it is preferred for a call.
