Hello,
If I make a HTML tab in jabber, and I call "SubscribePresence" as described here: http://www.cisco.com/c/en/us/td/docs/voice_ip_comm/jabber/11_6/cjab_b_feature-configuration-for-cisco-jabber/cjab_b_feature-configuration-for-cisco-jabber_chapter_01.html
This works, I can subscribe to the status of users and I get events in OnPresenceStateChanged. But I have no knowledge if I'm subscribed to something; If I subscribe and I refresh the page, I'll have to subscribe again because I don't know that I've already subscribed and I'll start receiving presence changes multiple times.
What I'm looking for is functions like UnsubscribePresence(), and GetSubscribedPresences(), but I can't find any kind of mention of this on the internet or in manuals. SubscribePresence isn't very useful without these functions, Am I doing something wrong?
