Figure 4: Using XT Endpoint for NAT and Firewall Traversal

Regarding GLAN1 and GLAN2 configuration, the XT Endpoint communicates simultaneously with

the public and private network endpoints using IP addresses (see Figure 4: Using XT Endpoint for

NAT and Firewall Traversal on page 18).

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.
