To Microsoft Lync Server via B2BUA

Click Save.

Repeat for all domains supported on Lync (that are not used in the video network).

Calls can now be made between SIP / H.323 endpoints registered on the video network to Lync clients registered on
Lync Server.

Test Calls from Internal Endpoint to Internal Lync Client

Test calls from endpoints registered on the video network to Lync clients registered on Lync Server.

For example, call david.jones@example.com or alice.parkes@example.com from both SIP and H.323 endpoints
registered on VCS Control.

Note that if Lync for Mac OS X is used and a Cisco AM GW is not installed, the call will result in an audio only call as
Lync for Mac does not support any video codecs supported by standards-based endpoints.
