Edge
Edge
Use this feature to enable single sign-on for endpoints accessing Unified Communications services from
outside the network. Single sign-on over the edge relies on the secure traversal capabilities of the VCS pair at
the edge, and trust relationships between the internal service providers and the externally resolvable identity
provider (IdP).
outside the network. Single sign-on over the edge relies on the secure traversal capabilities of the VCS pair at
the edge, and trust relationships between the internal service providers and the externally resolvable identity
provider (IdP).
The endpoints do not need to connect via VPN; they use one identity and one authentication mechanism to
access multiple Unified Communications services. Authentication is owned by the IdP, and there is no
authentication at the VCS, nor at the internal Unified CM services.

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.
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 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.
