2801 Router With CME, CUE & BT (PSTN) network

I have a 2801 Router With CME and CUE installed on it.  CUE will work as an IVR. I want to connect it to BT (PSTN, ordinary telephony network, UK) network and receive call from BT

Is there any one who can guide through step by what hardware do I need, and how to configure it.

Hi,What sort of a connection


What sort of a connection will you be using ? Is it gonna be a PRI or a SIP trunk or analog (FXO line) ?

Dial-peers would be needed anyhow to route the calls inbound and outbound. However, if you can update me a bit about the type of connection, we can take a look at the hardware etc.

Ok. Interesting. I find

Ok. Interesting. I find analog a bit finicky but they are fun to play with.

Now, for inbound calls, you would need to configure "connection plar" under the fxo voice ports and an inconming pots dial-peer. 


Eg- voice-port 0/0/0 

          connection plar <destination>

now the destination can be any number or extension that you want the calls to go. Just remember, analog lines do not have a called party/destination number. Plar command sort of populates thar field. 

You need to configure this command under all the fxo ports. The destination can be same or it can be different.

An incoming dial-peer would be something like -

dial-peer 1 pots 

   incoming called-number .


   no vad


For outbound, lets take an example of a local 10 digit call. The dial-peer would look something like -

dial-peer 10 pots

    destination-pattern 9[2-9]..[2-9]......

    port <fxo port number>

    forward-digit 10 


The above dial-peer would attempt to send a call for a 10 digit number using 9 to get outside dial-tone.

Likewise you can configure other dial-peers for different destinations.
