The module then alters the SDP appropriately and the opensips script continues on deciding where to send and sending the SIP message to the next server.<div>

Hi,<br>
<br>
as I already invested a lot of time, I try to be sure to check out all<br>
possibilities. I already know about PJSIP but that does not mean that<br>
OpenSIPS could not be the right project for me - I wanted to be sure.<br>
Anyway: Thanks A LOT for your very nice support and searching time!!!<br>

SDP is just signaling, OpenSIPS doesn't deal with RTP at all.<br>

IIRC, PJSIP does have stereo support to some degree. A quick search returned<br>
