Refer the exhibit. All region, MRG and MRGL configurations are set to default values. The service provider supports only the G.711 codec. Calls from the IP Phone 7965 to the SIP service provider fail due to a codec miss match. Which action should you take to make this call work?
A. Assign the transcoder to an MRG and MRGL but do not apply the MRGL anywhere
B. Assign the transcoder to an MRG and MRGL and apply the MRGL to the phone 7965
C. set early-offer support on CUCM to "Disabled"
D. Disable SIP eary offer on the CUBE
E. assign the transcoder to an MRG and MRGL and apply the MRGL to the SIP TRUNK
F. set early-offer support on CUCM to "Mandatory"
Why not E?
Early offer doesn’t help with codec mismatch. It only means the sdp is in sip invite. If the called party does not support the codec the caller offer, you need transcoder regardless.
Sorry, thought was F. I agree, E
