If you used MTP required, you'll need to ensure that a G711 MTP is in
the MRGL of the SIP Trunk and the trunk is reset. All IPVMS ("built
in") MTP's support G711. If that call's still not working, you'll need
to analyze CCM traces and potentially SIP message traces on the trunk.

Also ->
-Enable Early Offer (MTP if needed) on the SIP profile (CUCM 8.5+) or
Effort Early Offer (no MTP) on the SIP Profile (CUCM 10.5+)

-MTP Required (any version)
MTP Required limits you to a single codec in the outbound offer
and ties your max permitted calls to the number of MTP Resources in
your MRGL.
Sreekanth's suggestion is the simplest to fix your specific problem,
but early offer usually works better overall with most Service providers.

This happens when the CUBE receives the prompt from the ITSP over
RTP and is not aware of where it has to stream this prompt because
CUCM does Delayed Offer by default. So Cube doesnt have the
phone's IP address.
You can fix this by forcing CUCM to send provisional
acknowöedgement by:
1. putting voice-class sip rel1xx require "100rel" on the dial
peers facing CUCM, and
2. Under sip profile of sip trunk facing CUBE, change the Rel1xx
parameter to Send Prack for all 1xx messages.

Subject: [cisco-voip] No ring back Tone For Switched off Mobile
Hi
The issue is, when call out to a Switched off mobile phone, the IP
Phone can't hear the correct ringback tone either Busy Tone nor
Service Provider's Ringtone, it hears normal Ringback tone same as
when the mobile phone switched on instead
The call flow:
IP Phone -- CUCM -- SIP Trunk-- CUBE --SIP Trunk -- Service
Provider .
(CUCM 7.5, VGW (2921)
