[asterisk-dev] Asterisk 18 Planning: Codec Negotiation

Over the years there have been numerous requests to improve the codec
negotiation process in Asterisk. Specifically, regarding what codecs are
offered, in what order, how Asterisk chooses which codec(s) to use, and of
course how transcoding is affected by that.

Well hopefully that wait will soon be over. Currently we have plans to work
on this for Asterisk 18. The bulk of that work will be around the addition
of new chan_pjsip options that will allow a user to better control codec
offerings, and order.

I've added a page to the wiki [1] beneath the Asterisk 18 roadmap page that
explains what those options are (along with a couple current codec related
ones), and how they will work. Please, if you have any interest in this
topic read through that page and let us know what you think, or how things
can be improved.
