[Serusers] SER/Jabber question

Hi all! I'm new to SER, and already I have a question regarding the SER to Jabber: If I setup the jabber.so module to interface to a jabber server for IM, what's the recommended way to monitor the presence status of the SIP IM client? For example, if a user with MSN Messenger registers with SER, and I set a rule that at registration the jab_go_online call will be made so this user is available on the jabber server, how do I monitor the Messenger user's presence? I mean, they're not subscribed to, so the Messenger client doesn't send presence updates to SER, and hence to the jabber server. Then, of course, if I do subscribe from SER, who maintains the state? Hmmmm.... Any help or examples would be terrific! Thanks! - Chris Chris Dingman dingman(a)avaya.com
