Cisco Cisco TelePresence Video Communication Server Expressway

Introduction 

 

Cisco VCS can be in: 
 

the same domain as OCS 

 

a separate domain from OCS 

 

the same and separate domains from OCS 

 

Same domain is used by FindMe™ entries on Cisco VCS, which register as MOC devices on 
OCS (using OCS Relay): 
 

domain static route(s) are set up on OCS to route calls to Cisco VCS’s separate domain(s) 

 

Presence is only supported Cisco VCS to OCS: 
 

“Off-line” and “Available” and “In-call” are supported for “same domain” OCS Relay FindMe™ 
users 

 

“Off-line” and “Available” (not “In-call”) are reported for “separate domain” users 

 

Passing MOC presence to devices registered to Cisco VCS is not supported. 

 

OCS does not accept call hold request - this means that MOC devices cannot be joined into a 
Multiway conference. 

 

MOC devices registering through a Microsoft Edge Server and then calling Cisco VCS registered 
endpoints is not supported: 
 

Cisco VCS registered devices calling OCS registered devices will work, but MOC devices 
registering through an Edge server get no video if they call a Cisco VCS registered endpoint 

 

Calls to Microsoft Mediation Servers from endpoints in the Cisco VCS video network is not 
supported. 

 

In H.323 / SIP interworking, Cisco VCS X4.2 and later code requests full picture updates to work 
around a “lack of video on MOC” problem. 

 

OCS can be connected to a cluster of Cisco VCS peers. 

 

Cisco VCS forces SIP encryption off on the OCS zone so that video endpoints do not need to 
have encryption turned off. 

 

Subzones are no longer needed on the Cisco VCS control for locally registered endpoints. 

 

Cisco VCS can be in: 
 

the same domain as OCS 

 

a separate domain from OCS 

 

the same and separate domains from OCS 

 

Same domain is used by FindMe™ entries on Cisco VCS, which register as MOC devices on 
OCS (using OCS Relay): 
 

domain static route(s) are set up on OCS to route calls to Cisco VCS’s separate domain(s) 

 

a domain static route is set up on OCS to route calls to Cisco VCS’s same domain devices 
(that are not OCS Relay FindMe™ entries) 

 

Presence is only supported Cisco VCS to OCS: 
 

“Off-line” and “Available” are “In-call” are supported for “same domain” OCS Relay FindMe™ 
users 

 

“Off-line” and “Available” (not “In-call”) are reported for “separate domain” users 

 

“Off-line” and “Available” (not “In-call”) are reported for “same domain” users which are not 
OCS Relay FindMe™ users 

 

Passing MOC presence to devices registered to Cisco VCS is not supported.
