Hi there,
I have the following call flow set-up:
CUCM 10.5 <==> SIP <==> CUBE 15.3 <==> SIP <==> Telco
Incoming calls work fine.
Outgoing calls to mobile only are failing. When the call is made the mobile phone will ring but one's its answered the call is drop. To me this would suggest that this a codec issue
Below are the debugs but the only thing I see is "SIP/2.0 500 Internal Server Error"

Change your outbound dial peer to use codec-class that has both G711 and G729 listed, based on the SDP content in the original INVITE you are only sending G711.

Found the resolution to this. Change made under the SIP Profile for the SIP Trunk
