SIP and H.323 endpoints making basic calls
SIP and H.323 endpoints can make calls via Cisco VCS Control to MOC/Lync clients registered to
OCS/Lync server.

Upspeeding from a voice call to a video call
If a voice call is made from a MOC/Lync client to a video endpoint registered to Cisco VCS Control
and then the video button is selected to enhance the call to a video call, the video endpoint will
correctly upspeed to video.

correctly upspeed to video.
Note that:
Interworking a MOC/Lync client to an H.323 endpoint, the call will only upspeed from voice to
video if the upspeed request occurs before the endpoint sends a BRQ lowering the connection
bandwidth.

Multiway generation of ad hoc conferences
Endpoints can join MOC/Lync clients into an ad hoc conference using the Multiway feature. When a
MOC/Lync client is transferred into a Multiway conference, the client will connect using audio only.
The MOC/Lync user will then manually have to enable video on the client after connecting to the
conference.

MOC/Lync client accessing OCS/Lync server through
Microsoft Edge Server
Microsoft Edge Server
When MOC/Lync registers to OCS/Lync through a Microsoft Edge Server, the sdp from MOC/Lync
client needs to be specially processed by the “OCS/Lync gateway” VCS. This processing is available
in the B2BUA available from VCS X7.0 when the Enhanced OCS Collaboration option key is loaded
on the VCS.

in the B2BUA available from VCS X7.0 when the Enhanced OCS Collaboration option key is loaded
on the VCS.
Prior to X7.0, and without the B2BUA enabled and the Enhanced OCS Collaboration option key
loaded, calls made from an endpoint registered to Cisco VCS to MOC/Lync client should work, but
calls made from MOC/Lync client to an endpoint registered to VCS are likely to result in audio and
video on the endpoint registered to VCS, but no video or audio at the MOC/Lync client.
