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. <br>

Also -> <br>
-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+)<br>

<br>
-MTP Required (any version)<br>
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. <br>
<br>
Sreekanth's suggestion is the simplest to fix your specific
problem, but early offer usually works better overall with
most Service providers.<br>

<div>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.</div>
<div><br>
</div>
<div>You can fix this by forcing CUCM to send provisional
acknowöedgement by:</div>
<div>1. putting voice-class sip rel1xx require "100rel" on
the dial peers facing CUCM, and</div>
<div>2. Under sip profile of sip trunk facing CUBE, change
the Rel1xx parameter to Send Prack for all 1xx messages.</div>
