<br>
Would like to ask you what we need to implement adaptive codec switching<br>
using SIP re-invites in the application.<br>
<br>
Adaptive codec switching is the codec parameters renegotiation (SIP<br>
re-invite) using network measurements of jitter and bandwidth between<br>
two legs. Would like to ask if we have a some docu defines this method.<br>
<br>
We have a lack of clients support it, but we may rely on open project to<br>
make it work. I suggest to use some kind of protocol extension to achive<br>
such behavior.<br>
