Refer to the exhibit. Cisco Unified CM users report that they hear dead air during call transfer but bi- directional audio resumes after the transferees answer the call. The transferees are located across a SIP trunk. A collaboration engineer is checking the SIP trunk configuration on the Cisco Unified CM Which Two configuration changes fix this problem? (Choose two)
A. Assign a Media Resource Group List to the SIP Trunk
B. Place a check mark on Media Termination Point Required
C. Make sure there is an Annunciator Resource available on the MRGL
D. Modify the call Classification on the SIP trunk to OnNet
E. Change the "Send H225 User Info" service parameter to "Use ANN for Ringback"
MTP is needed to anchor the call to the “Call Center”, MRGL to have the MTP resource to use
I think B & C
not sure i agree here with A). the SIP trunk’s device pool “Texas” may or may not have an MRGL – the question doesn’t provide enough information on this. i would think C may also be part of the correct answer since we don’t know if any MRGL has an annunciator configured?
