Caller ID on Cisco 2600 and 3600 Series Routers and Cisco MC3810 Multiservice Concentrators

Caller ID Configuration Task List

	Command	Purpose
Step 3
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
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.
