Conﬁguring Phone Lists

If any of the lines in your demand, backup, or bandwidth pool are ISDN lines or

synchronous lines using V.25bis signaling, you must provide the router with the

list of telephone numbers that it uses for calls to and from remote routers. When

you conﬁgure a line for Raise DTR signaling, the router ignores the phone lists.

Phone Lists for ISDN and V.25bis Dialing

You may deﬁne two phone lists for the router: the outgoing phone list and the

incoming phone list (only for ISDN). Each telephone number in these lists is the

phone number of a remote router, which may have one or more phone numbers.

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

lines in the pool may be used by many different circuits, which is why the

telephone numbers are part of each circuit’s conﬁguration and not the line’s

conﬁguration.

Using a Phone List for Placing ISDN Calls

The router uses the outgoing phone list to place a call to a remote router on an

ISDN network.

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

screening. If incoming ﬁltering is set to Enable, the router will match the calling

party’s phone number with a number on its incoming phone list. The router must

be able to identify the calling party and verify that the party is an authorized caller.

To create outgoing and incoming phone lists, follow the instructions in the

sections that follow.
