Lync: Lync Server configuration
The configuration will vary depending upon the architecture of the Lync Server installation.
If a Lync Director is in use then configure the Lync Director (pool) to trust the “Lync Gateway”
Cisco VCS and to route traffic to Cisco VCS. Other FEPs receiving calls for the Video domain will
not know how to route them, so will pass the calls to the Director for routing (Except for statically
routed SIP domain traffic which will be sent directly from each FEP towards the OCS/Lync
gateway VCS).

not know how to route them, so will pass the calls to the Director for routing (Except for statically

If there is just a hardware load balancer in front of a set of FEP pools, configure each FEP pool.
If there is just a single FEP, configure it.
To allow the “Lync gateway” Cisco VCS to communicate with Lync Server:
1. For a TLS (encrypted signaling) connection between the “Lync gateway” Cisco VCS and Lync
Server (recommended):
•
•
TLS must be allowed on Lync Server
For a TCP connection (not recommended):
•
•
TCP must be allowed on Lync Server
2. Configure Lync Server to trust the “Lync gateway” Cisco VCS(s).
3. Configure Lync Server media encryption capabilities.
Lync: Trust an “OCS/Lync Gateway” VCS (cluster)
Lync trust can either be set up for a single “OCS/Lync Gateway” VCS or multiple VCSs (for example
when using a cluster for “OCS/Lync gateway” VCS.
when using a cluster for “OCS/Lync gateway” VCS.
On Lync Server:
1. Select
Start > All Programs > Microsoft Lync Server 2010 > Lync Server Management Shell
.
2. Set one or more Lync Gateway VCSs as a trusted application for Lync Server (VCS is treated as
an application by Lync Server).

Use the command “
New-CsTrustedApplicationPool
” with the following parameters:
-Identity
: specifies the Lync Gateway VCS
cluster
FQDN. Please note that this name must
match the one specified in the certificate.
-ComputerFqdn
: specifies the Lync Gateway VCS
peer
FQDN (Specify the master VCS
FQDN if running a cluster), e.g. vcs01.ciscotp.com. Please note that this name must match
the one specified in the certificate.
the one specified in the certificate.
-Registrar
: specifies the FQDN of the registrar for the Lync pool
-Site
: specifies the siteID on which this application pool is homed
Note: It is possible to use the command “
Get-CsSite
” to get the full list of sites (SiteID) and
related pools.
-RequiresReplication
: specifies that this trusted application must not be replicated
between Pools (must be $false)
-ThrottleAsServer
: Reduces the message throttling as it knows the trusted device is a
server, not a client (must be $true)
-TreatAsAuthenticated
: specifies that this application is authenticated by default (must be
$true)
For example:
C:\Users\administrator.CISCOTP>New-CsTrustedApplicationPool -Identity
ocsvcs.ciscotp.com -ComputerFqdn vcs01.ciscotp.com -Registrar
feppool.ciscotp.com -site 1 -RequiresReplication $false -ThrottleAsServer
$true -TreatAsAuthenticated $true
ocsvcs.ciscotp.com -ComputerFqdn vcs01.ciscotp.com -Registrar
feppool.ciscotp.com -site 1 -RequiresReplication $false -ThrottleAsServer
$true -TreatAsAuthenticated $true
