Hi Guys,
Our customer wants to see the status (if it is busy or not ) of the fxo lines on the phone and that line is sharing with hunt-group .Actually they have four fxo's tide with trunk group FXO.
According to cisco
SCCP: Configuring an Advanced Key System Phone Trunk Line Configuration
Perform the steps in this section to:
•
Create directory numbers corresponding to each FXO line that allows phones to have shared or private lines connected directly to the PSTN.
•Enable direct status monitoring of the FXO port on the line button of the IP phone. The line button indicator, either a lamp or an icon depending on the phone, shows the in-use status of the FXO port during the duration of the call.
•Allow transferred PSTN FXO line calls to be automatically recalled if the transfer target does not answer after the specified number of seconds. The call is withdrawn from the transfer-to phone and the call resumes ringing on the phone that initiated the transfer.
Prerequisites
•FXO port for a private line automatic ringdown (PLAR) off-premises extension (OPX) connection must be configured; for example:
voice-port 1/0/0
connection plar-opx 801 <<----Private number
•Dial peers for FXO port must be configured; for example:
dial-peer voice 111 pots
destination-pattern 811 <<----Trunk-tag
port 1/0/0
this is telling to configure new dial-peer with the trunk-tag for the monitoring. or i can use my previously configured dial-peers with trunk-group?
dial-peer voice 101 pots
trunkgroup FXO (this one)
corlist outgoing National-PT
destination-pattern 905........
forward-digits 10
no sip-register
sorry for long question
