The outgoing phone list and incoming phone list contain the phone numbers of

remote routers. The router places outgoing calls using numbers in the outgoing

phone list and verifies incoming calls using numbers in the incoming phone list.

Each remote router may have one or more phone numbers. The router dials the

phone numbers in the order in which they occur in the list.

The local phone list contains the local router’s phone numbers. It uses these

numbers to identify itself when it places an outgoing call.

The following sections describe how the router uses phone lists for ISDN and

modem calls.

How ISDN Calls Use Phone Lists

For ISDN calls, the router uses the outgoing, incoming, and local phone lists. The

instructions to configure each phone list begin on page 15-4

Outgoing and Incoming Phone Lists

The router uses the outgoing phone list to place calls to remote routers on an

ISDN network.

The router uses the incoming phone list to implement incoming call filtering.

Incoming call filtering is a security feature that lets you identify a remote caller.

To operate this feature, you must purchase caller ID service from your ISDN

provider.

If you enable incoming call filtering, the router matches the caller’s phone number

with a number in the incoming phone list. The list contains the phone numbers of

only authorized callers. If the number is not in the list, the router rejects the call.

Note:

Outgoing phone lists are associated with a specific circuit, not with the

line, which the router uses for many different circuits. Consequently, the phone

numbers are part of each circuit’s configuration, not the line’s configuration.
