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

remote routers. The router places 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 a 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 13-4

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. The

list contains the phone numbers of only authorized callers. You use incoming call

filtering with caller ID service, which lets you identify a remote caller. If you

enable incoming call filtering, the router matches the caller’s phone number with a

number in the incoming phone list. If the number is not in the list, the router

rejects the call.Features such as callback for demand circuits rely on incoming call

filtering for certain callback modes. For more information about the callback

feature, see “Callback” on page 6-8.

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.

Caution:

To use incoming call filtering, you must purchase caller ID service.

If you enable incoming call filtering without having caller ID service, the

router rejects all incoming calls.
