Dynamic codec switching
I remember fairly well that there is dynamic codec negotiation in fs from a big thread here on the list. My question is can i use this to overcome transcoding difficulties for ringback. I have g729 licences on the box, but prefer amr for mobile connections. Can i send early media in g729 and then switch to amr for actual call?
Why not? You should try. During the voice communication, codecs switched well. At least with SIPUA that I tried to use.(not so much,btw) 2013/4/2 Daniel Ivanov <sertys@gmail.com>

Remember AMR only works in passthrough mode. Though that should be fine for a bridge. You're probably looking for this: http://wiki.freeswitch.org/wiki/Mod_commands#uuid_media_reneg On 1 April 2013 23:34, Daniel Ivanov <sertys@gmail.com> wrote:

Exactly the reneg. I revisited the thread and will try it as soon as i have time. Is there a call quality metric i can use to check periodically on socket api and change codec accordingly? On Apr 2, 2013 9:30 AM, "Steven Ayre" <steveayre@gmail.com> wrote:
