Incoming PSTN UK BT (POTS) dial problem

Hi

I have 2 IP phones 7940's connected to a C1760 router configured with 2xFXS ports and 2x FXO ports running CME v4.1

The 2 phones can each complete a successful outgoing call over the pstn line. When an INCOMING call is being received the caller hears one ring and nothing else?

Looks like you are missing dial-peers on the POTS lines to accept inbound calls.  Example:

dial-peer voice pots 100

direct-inward-dial

incoming called-number .T

port 1/0

!

dial-peer voice pots 100

direct-inward-dial

incoming  called-number .T

port 1/1

!

This assumes you don't require translations to get to extension 1000 and 1001.

HTH.

Hi

I was being a bit dim and not reading the CCNA Voice guide

Page 271 of the Cisco Press guide:-

When an incoming signal is detected CME doesn't know what to do with it unless you specify a PLAR (Private Line Automatic Ringdown)

config:-

voice-port 1/0

cp-tone GB

connection plar 1000

voice-port 1/1

cp-tone GB

connection plar 1000

With this config any of the 2 ports connected with a standard PSTN phone line will be forwarded instantly to x1000 i.e a receptionist if you can afford one!

Another important note is the cp-tone to the correct country otherwise the incoming caller knows they have dropped on a call system.

All I have to work out now is a timeout, if the incoming call is closed x1000 keeps ringing for approx 2 minutes

thanks

Steven
