<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>
