Multiple Lync Domains and Multiple Gateway VCSs
You can integrate Cisco collaboration infrastructure with more than one Lync domain if required. Wherever you put a
single VCS as a gateway, you could use a cluster instead.

Note:
If you are using the FindMe deployment, be aware that the B2BUA can only proxy registrations to one Lync
domain. If you want FindMe for multiple Lync Domains, you need to design your deployment with one gateway per
Lync domain.
Lync domain.
The diagram below shows the following different options:
1.
This option is used in this document; there is one gateway VCS (or cluster) into a single Lync domain.
2.
One gateway or gateway cluster serving multiple Lync domains. Requires multiple search rules to route the
calls to and from Lync correctly.
calls to and from Lync correctly.
3.
It is possible to configure multiple Lync domains with an independent gateway serving each. This option is not
exhaustively tested, nor is it described in this document.

4.
You should avoid configuring multiple gateways to serve one Lync domain.
With this deployment, calls from one video endpoint to another video endpoint that is called via its Lync
domain will get routed via Lync rather than directly through the collaboration infrastructure; users could lose
duo video, far end camera control, and possibly encryption and video quality.
