Voice-port configuration is the only special configuration required to support caller ID. To configure 
your voice network fully, use the reference information in the section 

 to perform the following tasks on your routers:

Configure your IP, ATM, or Frame Relay network to support real-time voice traffic.

Configure voice cards for codec settings.

Configure voice dial peers. Each dial peer defines the characteristics associated with a call leg.

The remainder of this section describes the steps required to configure caller ID on FXS and FXO voice 
ports.

To configure voice ports to support caller ID, use the following commands beginning in global 
configuration mode:

Router(config)# voice-port slot/port

or

Router(config)# voice-port 

slot-number/subunit-number/port

Enters voice-port configuration mode on a 
Cisco MC3810 multiservice concentrator. The slot 
number for analog voice ports on the Cisco 
MC3810 multiservice concentrator is always 1. 
There is no port 0 for voice ports.

Enters voice-port configuration mode on a 
Cisco 2600 or 3600 series router.

Router(config-voiceport)# connection {plar | tie-line 

| plar-opx} digits {trunk digits [answer-mode]}

Specifies the voice-port connection type and the 
destination telephone number. The keywords and 
arguments are as follows:

plar—Specifies private line automatic 
ringdown.

tie-line—Specifies a tie-line connection to a 
PBX.

plar-opx—Specifies a PLAR off-premises 
extension (the local voice port provides a local 
response before the remote voice port receives 
an answer).

trunk—Specifies a straight tie-line 
connection to a PBX.

answer-mode—Indicates whether a trunk 
connection is specified. The router should not 
attempt to initiate a trunk connection, but 
should wait for an incoming call before 
establishing the trunk.

digits—Specifies the destination telephone 
number.
