Hello all,
I have an ITSP provided SIP Trunk that will only allow the use of G711 codec.
I have some ip phones on remote sites that need to break out over this and the links are low bw so need to use G729 only
If I use Early Offer on the SIP trunk towards the CUBE via SIP Profile (mandatory insert MTP if required) then the call fails with a 488 media non-acceptable error because I offer G729 but the voice class codec on the Dial-peers facing CUCM only allow G711. Which is what you would expect.
So I need a transcoder and the only ways I can get the transcoder to invoke are:
Just wondering if anyone else has had this issue and has a better option ie where I can use Early Offer (mandatory insert MTP if required) but still have CUCM in charge of inserting the codec before the call fails?
Cheers

I will always go with Option 1. If you must use Early offer on CUCM, then use option 3.
