Hi, We have the JsSIP client that is webrtc based, and we have PJSIP client on other end. We are using reSIProcate for signaling between the JSSIP and PJSIP clients, for converting SIP over web socket to SIP. When the invite is going from JsSIP to PJSIP, PJSIP is throwing the following error message. "488 Not Acceptable Here for INVITE response" Does anybody faced this issue already? Thanks. -------------- next part -------------- An HTML attachment was scrubbed... URL: <http://lists.pjsip.org/pipermail/pjsip_lists.pjsip.org/attachments/20160204/7e791275/attachment.html>
