Command

Purpose

Step 3

Router(config-voiceport)# station-id number number

Configure the station number on FXS voice ports

connected to user telephone sets. This sets the

caller-ID information for on-net calls originated by

the FXS port.

You can also configure the station number on an FXO

port of a router for which incoming caller ID from the

PSTN subscriber line is expected. In this case, if no

caller-ID information is included on the incoming

PSTN call, the call recipient receives the information

configured on the FXO port instead. If the PSTN

subscriber line does provide caller-ID information,

this information is used and the configured station

name is ignored.

If the caller-ID station number is not provided by

either the incoming PSTN caller ID or by the station

number configuration, the calling number included

with the on-net routed call is determined by Cisco

IOS software by using a reverse dial-peer search. In

this case, the number is obtained by searching for a

POTS dial-peer that refers to the voice-port and the

destination-pattern number from that dial-peer is

used.

number is a string of 1 to 15 characters identifying the

station telephone or extension number.

Step 4

Router(config-voiceport)# caller-id block

(FXS ports only) When this command is configured at

the originating end of a call, it requests that the

originating calling party information not be displayed

at the called party's telephone.

Note The calling party information is included in

the routed on-net call, as this is often required

for other purposes, such as billing and call

blocking. The request to block display of the

calling party information on terminating FXS

ports will normally be accepted by Cisco

routers, but no guarantee can be made

regarding the treatment by other equipment.

This command affects all calls sent to an FXO station

from the configured FXS station. The central office

(CO) may supply a feature code that a user can dial in

order to block caller-ID transmission on a call-by-call

basis.

When a blocked-information call passes through an

FXO interface on the way to its destination, the

blocking is passed on to the receiving party.
