8. If Lync Server is a single FEP then the “Lync Gateway” Cisco VCS(s) should be configured to
route calls for Lync Server to the single FEP directly, and receive calls from the FEP:

configure the single FEP as the Peer address in the neighbor zone

Prerequisites prior to configuring Cisco VCS and Lync Server
to interoperate
to interoperate
Before configuring the Video Network and the Lync system to interwork, make sure that the following

Lync Server is configured and operational and access is available to Active Directory for
managing users.

The FQDN of Lync Server (enterprisepool.test-customer.com in this example) is resolvable via the
DNS server that Cisco VCS Control is configured to use. DNS servers should be the same for
VCS Control and Lync Server.

The FQDNs of each of the “Lync gateway” Cisco VCSs and the FQDN of the “Lync gateway”

The video endpoints registered to the Video Network must support the H.263 video codec – this is
the only video codec which is common to Lync clients and standard video endpoints.

If TLS is to be used (recommended) ensure that the DNS server supports reverse DNS lookup
