Hi, I currently have a soft phone that is based on pjsip, I am now looking at using RFC 4353 conferencing to turn the soft phone into a conference-aware UA. >From what I can see RFC 4353 is not supported within pjsip, but was hoping someone could confirm this? If its not supported, I would be grateful if someone could point me in the right direction on where to start on implementing this, eg some kind of module, or just a hack. Many Thanks
