ABOUT DIALING

UT TO THE ISDN

ETWORK 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.
