3. For each domain, turn On the services for that domain that VCS is to support. The available services are:
l
SIP registrations and provisioning on VCS: the VCS is authoritative for this SIP domain. The VCS
acts as a SIP registrar and Presence Server for the domain, and accepts registration requests for any
SIP endpoints attempting to register with an alias that includes this domain.

SIP registrations and provisioning on Unified CM: endpoint registration, call control and

Turn On all of the applicable services for each domain. For example, the same domain may be used by
endpoints such as Jabber or EX Series devices that require line-side Unified Communications support,
and by other endpoints such as third-party SIP or H.323 devices that require VCS support. (In this
scenario, the signaling messages sent from the endpoint indicate whether line-side unified
communications or VCS support is required.)

Discovering IM&P and Unified CM servers
The VCS Control must be configured with the address details of the IM&P servers and Unified CM servers
that are to provide registration, call control, provisioning, messaging and presence services.
that are to provide registration, call control, provisioning, messaging and presence services.
Note that IM&P server configuration is not required in the hybrid deployment model.
Uploading the IM&P / Unified CM tomcat certificate to the VCS Control trusted CA list
If you intend to have TLS verify mode set to On (the default and recommended setting) when discovering
the IM&P and Unified CM servers, the VCS Control must be configured to trust the tomcat certificate
presented by those IM&P and Unified CM servers.

1. Determine the relevant CA certificates to upload:
l
If the servers are using self-signed certificates, the VCS Control's trusted CA list must include a copy
of the tomcat certificate from every IM&P / Unified CM server.

If the servers are using CA-signed certificates, the VCS Control's trusted CA list must include the root
CA of the issuer of the tomcat certificates.
