How it works
Cisco Jabber determines whether it is inside the organization's network before it requests a Unified
Communications service. If it is outside the network, then it requests the service from the VCS Expressway
on the edge of the network. If single sign-on is enabled at the edge, the VCS Expressway redirects Jabber to
the IdP with a signed request to authenticate the user.

The IdP challenges the client to identify itself. When this identity is authenticated, the IdP redirects Jabber's
service request back to the VCS Expressway with a signed assertion that the identity is authentic.

The VCS Expressway trusts the IdP, so it passes the request to the appropriate service inside the network.
The Unified Communications service trusts the IdP and the VCS Expressway, so it provides the service to
the Jabber client.

Improved line-side capabilities
The line-side SIP capabilities of the VCS have been extended to improve the support that MRA offers for
endpoints registering to Unified CM. The improvements are:
endpoints registering to Unified CM. The improvements are:
Early Media support over MRA
Support for this feature means that endpoint users can hear media from the far end before the call is fully
established, to indicate call progress (eg. busy tone) or play interactive voice responder messages.
established, to indicate call progress (eg. busy tone) or play interactive voice responder messages.
The MRA deployment now supports passing through the 183 provisional response to enable early media, but
the feature is dependent on endpoint support. Early media is supported in recent software for TC series
endpoints but is not supported in Jabber 10.6.
