if these items are not configured and the connection between OCS/Lync server and VCS is TLS,
then although the neighbor zone goes active and VCS can send messaging to OCS/Lync server,
OCS/Lync server will never open a TLS connection back to VCS, resulting in no calls from
OCS/Lync to VCS and other strange behavior.

“OCS/Lync gateway”: Ensure that cluster name is configured
This should be configured whether the Cisco VCS is part of a cluster or not; this value is used with
FindMe as well as clustering.
FindMe as well as clustering.
For each “OCS/Lync gateway” VCS peer, ensure that Cluster name is the same, and is set up to be
the FQDN of the cluster. Note that this should have been set up when the cluster was created – see
“Cisco TelePresence Video Communication Server Cluster Creation and Maintenance Deployment
Guide (X7.0)”. If the cluster name needs changing follow the procedure in that document.

“OCS/Lync gateway”: Configure an NTP server
On each “OCS/Lync gateway” VCS Control peer:
1. Go to the
Time
page (
System > Time
).
2. Set NTP server 1 to the IP address of an NTP server.
3. Optionally set NTP server 2 to the IP address of an additional NTP server.
4. Set Time zone as appropriate to the location of the Cisco VCS.
Note: you can find out which time server that the Windows server (the OCS/Lync server) is using by
typing ‘net time /querysntp’ from the windows command line. (For Windows 2008/2008 R2 use
‘w32tm /query /peers’ to get a list of time servers currently in use.)

“OCS/Lync gateway”: Switch on TLS in SIP configuration
1. Go to the
SIP
page (
VCS configuration > Protocols > SIP > Configuration
).
2. Ensure that TLS mode is On.
