hello, I would like to know if it's possible to change the codec of a call in the middle of the call. I have an asterisk without g729 codecs and I recieve an incoming call. The codec is negotiated in ulaw althought who is calling have a g729 codec. My * plays and announcements and call and extension to pass the call to it. The extension have a g729 codec too. It is possible to change the codec of incoming call from ulaw to g729 and then asterisk bridge the calls? thanks for the help.
