Cisco Systems 2600 appendix Configuring FXS and FXO Voice Ports to Support Caller ID, VC-818

Command

Purpose

Step 1

Router(config)# caller-id enable

Enables caller ID. This command applies to FXS

voice ports that send caller-ID information and to

FXO ports that receive it. By default caller ID is

disabled.

Note If the station-id or a caller-id alerting

command is configured on the voice port,

these automatically enable caller ID, and the

caller-id enable command is not necessary.

Step 2

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

Configures the station name 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 name

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.

The name argument is a character string of 1 to 15

characters identifying the station.

Note This command applies only to caller-ID calls,

not Automatic Number Identification (ANI)

calls. ANI supplies calling number

identification only.
