Configuring domains
The
Domains
page (
Configuration > Domains
) lists the domains managed by this Expressway for Unified
Communications services.
A domain name can comprise multiple levels. Each level's name can only contain letters, digits and hyphens,
with each level separated by a period (dot). A level name cannot start or end with a hyphen, and the final level
name must start with a letter. An example valid domain name is 100.example-name.com.
with each level separated by a period (dot). A level name cannot start or end with a hyphen, and the final level
name must start with a letter. An example valid domain name is 100.example-name.com.
Note that values shown in the Index column correspond to the numeric elements of the %localdomain1%,
%localdomain2%, . . . %localdomain200%
%localdomain2%, . . . %localdomain200%
You can configure up to 200 domains. (Note that you cannot configure domains on an Expressway-E.)

Communications
must select the services that each domain will support. The options are:
n
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. The default
is On.

setting is absent if there is only one deployment (there is always at least one).
setting is absent if there is only one deployment (there is always at least one).
Any domain configuration changes, when one or more existing domains are configured for IM and Presence
services on Unified CM or XMPP Federation will result in an automatic restart of the XCP router on both
Expressway-C and Expressway-E.
services on Unified CM or XMPP Federation will result in an automatic restart of the XCP router on both
Expressway-C and Expressway-E.
The end-user impact is temporary loss of federation and any Jabber clients using mobile and remote access
will be temporarily disconnected. The clients will automatically reconnect after a short period.
