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 6-5.

Local Phone Lists

For BRI connections, the router uses the local phone list for the following

purposes:

• To identify itself when it places a call to a remote router. The local router

includes its own phone number in the ISDN outgoing call setup message.

• To identify itself to the ISDN switch so that the switch can activate the circuit.

In the United States and Canada, the Service Provider ID (SPID) is also

required.

• To ensure that an incoming call was received at the intended destination.

When the local router receives a call, it checks that the phone number in the

incoming call setup message is the same as its own local phone number.

• To facilitate BAP negotiations for bandwidth-on-demand service. The

non-monitor router passes a local phone number to the monitor router when

the monitor router requests additional bandwidth. When the monitor router

receives the phone number, it uses that number to call back the non-monitor

router, which then activates another line.

How V.25bis and Hayes Calls Use the Outgoing Phone List

For V.25bis and Hayes calls, the router uses only the outgoing phone list. The

router passes the remote router’s phone number to the modem to establish a

connection.

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.
