Notes:
■
The Gateway VCS that connects to the Lync Server must be the presence server for any SIP domains that
Lync Server might want to look at for presence; this limits the number of VCSs that Lync server’s presence
requests will travel through.

Presence requests use up SIP resources and with Lync typically having thousands of 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.

Configure the Lync Clients
1.
Set up Sign-in address as required. This is the SIP URI of the Lync user.
If the Lync user also has video endpoints on the video network, the Sign-in address is the same URI you
entered as the B2BUA registered FindMe user ID, for example david.jones@example.com.
entered as the B2BUA registered FindMe user ID, for example david.jones@example.com.
2.
Log in to the Lync Client.
Lync Server will not provide presence for FindMe users to other Lync clients until the Lync client associated
with a FindMe has been signed into using a Lync client registered to Lync Server.
with a FindMe has been signed into using a Lync client registered to Lync Server.
3.
Repeat for each FindMe user that has not already signed into Lync
Test Calls and Presence with Lync Clients
Verify FindMe Registrations
After the FindMe accounts have been configured for at least 60 seconds:
1.
On the Gateway VCS, go to Status > Applications > Lync users.
2.
Verify the following for each FindMe user:
—
Registrations state is Registered
—
Presence state is Online (if Default published status for registered endpoints is set to Online, otherwise
expect to see Offline)
expect to see Offline)
—
Subscription state is Subscribed
3.
If the states are not as expected, check that the FindMe and Lync (Active Directory) registered names are
identical.
