Note: The “OCS/Lync gateway” VCS that connects to the OCS/Lync Server must be the presence
server for the SIP domain that the “OCS/Lync gateway” VCS shares with OCS/Lync server. It should
also be the presence server for any other sip domains that OCS/Lync server might want to look at for
presence; this limits the number of VCSs that OCS/Lync server’s presence requests will travel
through.

presence; this limits the number of VCSs that OCS/Lync server’s presence requests will travel

Presence requests use up SIP resources and with OCS/Lync typically having thousands of
MOC/Lync clients connected that may be requesting presence, it is best to limit the range of where
the presence requests can go, especially not letting them reach VCSs that may already be heavily
used for taking calls.

The “OCS/Lync gateway” must also be the presence server for the domains of all devices that are
referenced in the FindMe users that register to OCS/Lync, as FindMe will only aggregate presence
data for devices where their presence state is known on the same VCS as the FindMe resides.

Log in to the OCS/Lync client
OCS/Lync Server will not provide presence for FindMe users to other MOC/Lync clients until the
MOC/Lync client associated with a FindMe has been logged into using a MOC/Lync client registered
to OCS/Lync server.
MOC/Lync client associated with a FindMe has been logged into using a MOC/Lync client registered
to OCS/Lync server.
For each FindMe user that has been created and not already been logged into:
1. Log into an OCS/Lync client as that user.
2. Log out.
3. Repeat for all users.
