Connecting To The Collaboration Server In Ice Environment; Dialing Methods - Polycom RealPresence 800s Administrator's Manual

Connecting to the Collaboration Server in ICE Environment

The dialing methods that can be used by an endpoint to connect to another endpoint
depends on the ICE environment: Local, Remote or Federation.
Figure I-1
Local connection - a connection between the Collaboration Server and endpoints that reside
within the same organization. For example, an endpoint in Zone A calls the Collaboration
Server in Zone A.
Branch Office - a connection between an endpoint that is behind a firewall and the
Collaboration Server that reside in the same zone. The user in the Branch Office can also
place and receive calls from other enterprises and remote users. For example, Enterprise A
also contains a branch office, which in this example is a Polycom HDX user who is behind
more than one firewall.
Remote - a connection between Collaboration Server that resides within the organization and
an endpoint that resides outside of the organization (on a WAN). For example, an endpoint
on the internet that calls the Collaboration Server in Zone A. In such a case, the call has to
traverse at least one firewall.
Federation - a connection between Collaboration Server that resides within one organization
and an endpoint that resides within another organization. For example, an endpoint in Zone
A calls the Collaboration Server in Zone B. The call has to traverse two or more firewalls.

Dialing Methods

The ICE protocol enables remote and federation connections using the registered user name
for dialing. The endpoint connects to the Collaboration Server by entering the Collaboration
Server registered user name in the following format:
[Collaboration Server registered user name]@[Lync server domain name]
For example: rmx111@ilsnd.vsg.local
The call reaches the Transit Entry Queue of the Collaboration Server and via IVR is routed to
the destination conference.
This method is added to the local connections and the Numerical Dialing method available in
the Lync server environment.
The following table summarizes the dialing methods and its availability in the various
configurations.
