Configuring the domains to route to Unified CM
You must configure the domains for which registration, call control, provisioning, messaging and presence
services are to be routed to Unified CM.

1. On Expressway-C, go to
Configuration > Domains
.
2. Select the domains (or create a new domain, if not already configured) for which services are to be routed
to Unified CM.
3. For each domain, turn On the services for that domain that Expressway is to support. The available
services are:
l
SIP registrations and provisioning on Unified CM: Endpoint registration, call control and
provisioning for this SIP domain is serviced by Unified CM. The Expressway acts as a Unified
Communications gateway to provide secure firewall traversal and line-side support for Unified CM
registrations.

by the Unified CM IM and Presence service.
l
XMPP federation: Enables XMPP federation between this domain and partner domains.
l
Deployment: Associates the domain with the selected deployment, if there are multiple deployments.

Turn On all of the applicable services for each domain.
Note that these settings are not entirely independent. You cannot disable SIP registration and
provisioning while using IM and Presence. You can disable IM and Presence while SIP registrations
and provisioning on Unified CM is On, but the reverse is not true. So, if you switch IM and Presence
Service On, then your setting for SIP registrations and provisioning is ignored and the Expressway-C
behaves as though it was On.
