Refer the exhibit. An engineer configured two Cisco Telepresence CTS 3000 endpoints to an existing environment using a Cisco Unified Communications Manager (CUCM) clustery CUVC and a CTMS for interoperability. The quality is assigned to be high-definition (720p), however, video quality is not as expected. The output trace shows an INVITE SDP coming from the CTS 3000. What is the root cause of the problem?
A. The level-asymmetry-allowed parameter is enabled in the CTS-3000
B. the CUVS interoperability maximum call rate is set to 12288 kbps
C. the region bandwidth that is configured in CUCM cannot support a 720p call
D. The CTMS static meeting interoperability resolution is set to CIF
