If endpoints are registered to Cisco VCS Control, it must be configured as the SIP Registrar/H.323
gatekeeper.
In order for CMR Hybrid to work with endpoints registered to Cisco VCS Control, it is required to set up a
Cisco VCS Control as a SIP registrar, enabling it to register SIP devices and route calls to them. Cisco
VCS Control has the capability to be both an H.323 gatekeeper and a SIP registrar.
Configuring Cisco VCS Control as a SIP registrar is done by configuring one or more SIP domains. The
Cisco VCS Control will act as a SIP Registrar and Presence Server for these domains, and will accept
registration requests for any SIP endpoints attempting to register with an alias that includes these
domains.
For details on how to configure SIP domains in Cisco VCS Control, refer to the "Cisco TelePresence
Video Communication Server Basic Configuration (Control with Expressway) Deployment Guide" at:

Intercompany TelePresence participants: If you want to allow participants from another company to be able
to join via TelePresence, you must have a valid SIP SRV (secure SIP), non-secure SIP SRV or multiple
SIP and H323 SRV records in place that resolve to the Cisco VCS Expressway for your configured SIP
Domain so TelePresence participants can route to your Cisco VCS Expressway.
