hmm I thought that it only was the codec_prefs_XXXX that was not implemented
could we then add a note in the config that it is not implemented or remove it as "codec_prefs_XXXX" has been in (ASTERISK-29109)

> when using the outgoing_call_offer_pref=remote the list in the 200/183 is not filtered to only contain what is the common denominator
> INVITE from A with G722,PCMA,PCMU
> INVITE to B the order is reversed PCMU,PCMA,G722
> 183 from B PCMA,PCMU (no G722)
> 183 to A PCMU,PCMA,G722 (G722 is not removed!)
> endpoint/allow=!all,alaw,g722,ulaw
> endpoint/incoming_call_offer_pref=remote
> endpoint/outgoing_call_offer_pref=remote
> ;remote - Include all codecs in the remote list that are also in the local list preserving the remote order.
