Dialing Methods - Polycom RealPresence 800s Administrator's Manual

RealPresence Collaboration Server (RMX) 800s/Virtual Edition Administrator's Guide
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]@[OCS/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 Matched URI and Numerical Dialing methods available
in Microsoft Office Communication environment 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.

Federation
* To enable the Matched URI dialing in the federated environment to be able to connect to the Collaboration
Server SIP signaling domain, you must also configure the Office Communications Server/Lync Server.
When federating an Office Communications Server/Lync Edge server with another Office Communications
Server/Lync server environment, you need to include the FQDN of the Office Communications Server/Lync
Edge server as well as the SIP signaling domain for federated environment. The SIP signaling domain is
the FQDN of the Polycom DMA system or a Polycom Collaboration Server system (when your deployment
does not include a DMA system).
For example, if company B wants to set up federation with company A and receive and send SIP calls that
will be handled by the Polycom SIP signaling domain in company A, you need to add the FQDN of the
company A Office Communications Server domain as well as the SIP signaling domain of company A to the
list of internal SIP Server domains supported by the company B Office Communications Server/Lync Server
environment.
For more information, see the Microsoft documentation and the
Deployment Guide for Microsoft® Environments.
