Step 3
Router(config-voiceport)# station
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 either by 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, using a reverse dial-peer search. 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.
The 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 is normally
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.
