Hi All,

When two useragents subscribed to peer-peer Presence.

For example:

 UserAgentA ----SUBSCRIBE-------> UserAgentB
 UserAgentA <----200OK------- UserAgentB
 UserAgentA <----NOTIFY(ONLINE)------- UserAgentB
 UserAgentA <----SUBSCRIBE------- UserAgentB
 UserAgentA ----200OK-------> UserAgentB
 UserAgentA ----NOTIFY(ONLINE)-------> UserAgentB

 After Sometime UserAgentB restarted, before it goes to reboot, it send
UnSubscribe to UserAgentA.

 UserAgentA <----SUBSCRIBE(Expires:0)------- UserAgentB
 UserAgentA ----200OK(Expires:0)-------> UserAgentB

 What would be expected behavior on UserAgentA?

   - should carry UserAgentB has a online/offline on UserAgentA ?
   - when UserAgentA receives subscribe(from UserAgentB) with expires 0,
UserAgentA should remove the status  of UserAgentB?

Any response is highly appreciated.

Thanks in advance

Regards
Sudhir
