Dear All, .May be I couldn't express my doubt properly ijn my earlier mails.Actually we were testing OfficeSIP server with SipML5 client for multiparty videoconferencing with presence enabled for showing buddy list and it is working properly.Now as we moved to kamailio with same client and configuring kamailio with Websocket and presence support, I have noticed that the presentity and xcap tables are not populated but location,watchers and active watchers tables are showing correct entries after a user logs in using sip over websocket from SIPML5. I have followed the steps as described in " http://kb.asipto.com/kamailio:presence:k31-made-simple"quot;. As Sipml5 sends PUBLISH/NOTIFY request in pidf format is this is the possible cause?As I am a person from java based web application technology it is really hard for me to detect the root cause.Please give me some idea regarding this issue.
