Hi! I'm developing an IM client based on the PJSIP stack and having some problems with the PUBLISH refresh packets being sent from it. Our server demands the User-Agent field to be present in the header, with a certain signature, but PJSIP doesn't add the UA field when it refreshes the presence. The UA field is only added when it sends a normal PUBLISH. This is not actually a big problem, but is there a way of adding the UA field when it refreshes its presence to get rid of the "501 Method Not Supported Here" message that the server answers with? By the way, thanks for a great piece of software with excellent documentation! Best regards, Andreas Backman SESCA ISW -------------- next part -------------- An HTML attachment was scrubbed...
