I have a question regarding SIP Trunk configuration/capability. My SIP trunk is configured with Media Termination Point Required. When configuring the MTP Preferred Originating Codec if I choose 711alaw does that mean that G.728 will also work across this SIP Trunk?
Based on a TAC case I have open at the moment the answer appears to be no. Apparently, once the MTP is allocated a final codec selection is chosen between the MTP and the calling endpoint. The final called party must support that codec or a transcoder will be invoked.
