In releases earlier than 7.0, for Lync integration, the administrator had to administer the Presence Services handle of an Avaya Aura® user twice as:
Avaya Presence/IM (formerly XMPP) handle
Avaya SIP handle
The duplicate administration was required for proper routing of the Lync originated subscription and IM requests.
Starting with Session Manager Release 7.0, the Presence Services handle is administered only once.
To support tighter integration with Microsoft Lync, Session Manager:
Supports routing rules, configured in System Manager, to deliver Lync Presence/IM traffic to Presence and Avaya Multimedia Messaging as appropriate.
Recognizes and routes on the Presence/IM handle type.
Inserts the media type (mtype) parameter in the Route header when routing to SIP entities.
Note:
The Lync server does not connect with a Branch Session Manager in branch locations.
