Users report that they do not see a high-quality picture on the high-definition endpoints when they call into Cisco Meeting Server. An engineer must extract the SDP that is offered by Cisco Meeting Server from the SIP traces to troubleshoot .
What is the cause of this issue?
A . Cisco Meeting Server is not configured for
B . 265 to support high-definition video calling.
C . The AES ciphers are not compatible with high-definition video calling.
D . The Content-Length value in the SDP does not support high-definition video calling.
E . The SIP call bandwidth is not at a value that supports high-definition video calling.
Answer: D
