External XMPP federation
This section describes how to configure your VCS to support external XMPP federation.
Deploying VCS for external XMPP federation
External XMPP federation enables users registered to Unified CM IM & Presence to communicate via the
VCS Expressway with users from a different XMPP deployment.
VCS Expressway with users from a different XMPP deployment.
The following diagram shows how XMPP messages are routed from your on-premises IM & Presence server
via the VCS Control and VCS Expressway Collaboration Edge solution to the federated XMPP server. It also
shows the ports and connections that are used as the messages traverse DMZ firewalls.

VCS Expressway does not support XMPP address translation (of email addresses, for example). External
systems must federate with the Jabber IDs that are native to Unified CM IM & Presence.
You can make the user's Unified CM IM&P Jabber ID resemble the user's email address, so that the
federated partner can use email addresses for federation, by:

setting the Unified CM LDAP attribute for User ID to be the user's sAMAccountName
l
setting the Unified CM IM&P presence domain to be the same as the email domain

Simultaneous internal federation managed by Unified CM IM&P and external federation managed by VCS
is not supported. If only internal federation is required then you must use Interdomain Federation on Unified
CM IM&P. The available federation deployment configuration options are:
