Using a fairly recent SVN version of pjsip, (it has been like since first version I tried in December) calling an Xlite phone does not work. I could provide a SIP Packet Capture if it might help... But, the issue seems so easy to reproduce that I think that is not needed. Basically, when calling from pjsip client (pjsua demo) to Xlite phone, it gets the INVITE message, and sends 200 OK - but with no media. Hence, there is a connected call, but for whatever reason, media negotiation broke. Happens always... which is why I wonder why no one else has mentioned this? It seems to me that something pjsip is sending is breaking xlite's ability to chose a codec (I tried enable all codecs and enabling just PCMU). However, when Xlite calls pjsip client, everything works as expected. I think Xlite is broken in someway, as the pjsip client (so far) has been able to place calls to any other SIP device. But, Xlite seems like it is fairly widely used, so I hope that the issue is a simple fix. It is possible that the issue is somehow caused from the SIP Proxy I am using to call through, but since everything else but Xlite phone is working great, I don't really see how.
