Supporting ISDN Connectivity

About this task
The Scopia XT Endpoint for IP Office supports ISDN connectivity, allowing calls from endpoints to be
routed to the relevant videoconference via the Scopia Gateway for ISDN.
For deployments without a gatekeeper, you can dial ISDN endpoints by simply dialing the ISDN number.
To do so, you must first configure the endpoint with your Scopia Gateway for ISDN, as described below.
The system then automatically and transparently takes care of setting the bit rate and call routing
through the Scopia Gateway.
A single gateway can serve multiple endpoints. For example, if your organization needs to enable 5
Scopia XT Endpoint for IP Office endpoints with ISDN connectivity (at a speed of 256bps), you can use
one the Scopia Gateway for ISDN, which supports 5 concurrent calls of 256bps each.
