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 Expressway-E on
the edge of the network. If single sign-on is enabled at the edge, the Expressway-E 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

Unified Communications service trusts the IdP and the Expressway-E, so it provides the service to the
Jabber client.
