<TITLE>Audio calls with ICE</TITLE>

<FONT FACE="Calibri, Verdana, Helvetica, Arial"><SPAN STYLE='font-size:11pt'>Hello,<BR>
<BR>
I’m using sipsimple for client code and the server is OpenSIPS. I’ve enabled ICE on the clients by setting account.nat_traversal.use_ice=True but with some machines I’m not able to start the audio call. However if I deactivate ice from the use_ice setting I’m able to start the call.<BR>
What happens is, I have a MSRP chat session with that user and I’m trying to send an INVITE to add an audio stream but the server apparently does not respond at all to that INVITE.<BR>
<BR>
Thank you, <BR>
