Re: FXS port

Balamurugan,

              Yes it is possible for a PSTN line that is connected in a cisco voice gateway to directly ring an internal ip phones extension. A PSTN line that connects to a cisco voice gateway(2800 router for example) must use an FXO port, not FXS.  FXS is for end stations such as phones.  FXO ports connect to the PSTN.  You can use the plar command on the FXO voice-port, such as this.  The plar command sends any incomming call recieved on that voice-port to the extension in the connection plar command.

voice-port 0/0/0
connection plar 2000 ------> if someone calls the PSTN line connected to voice-port 0/0/0, then the voice gateway will send the call to extension 2000.
