I am integrating Zimbra UI with our backend server. I have enabled IM messages and I can see the roster but the UI is not sending the NoOpRequest as frequently as it should.
Do I need to send something more in the notify block of IMGetRosterResponse other than the elements given below?
// Asynchronous Roster Response
<n type="subscribed" to="TOADDR" name="NAME" groups="">
// Presence update for a specific user
<n type="presence" from="FROMADDR" [show="ONLINE"]/>
