This section provides sample scenarios for using the SCOPIA Gateway with
configuration details and dialing examples, including the following:
About Dialing Out to the ISDN Network via the Gateway
About Dialing In to the IP Network via the Gateway
This section describes how to dial between IP and ISDN networks using the
Gateway.
Note
References to the ISDN network refer also to the serial side of the Serial
Gateway. The references to B-channels refer also to the equivalent bandwidth for
the Serial Gateway. To obtain the actual serial call rate, multiply the number of
channels by 64 Kbps (56 Kbps for restricted calls).
When you dial out from an IP network to an ISDN network, you dial a service
prefix followed by a string that usually includes the destination area code, the
destination phone number and any required extra characters such as an asterisk
(*), pound sign (#) or delimiter. The service prefix indicates that the call is to go
through the Gateway, and also indicates the properties of the call such as the call
type or bandwidth requirements.
