What to add in extensions.conf for isdn30 communication

In the testenvironment:

I have a system with 2 ISDN30 ports and Asterisk 1.2.8 running on it.
I use port 1 of the ISDN30 card.
There is an internal SIP phone with number 46004
In the PSTN there is a number 201

I want to call from 46004 to 201 and vice versa.

Question:

What must be added in the extensions.conf file to realize this ?

THX!!!

nothing special, but you need to show us your zapata.conf file as a minimum. something like

[code][outgoing]
exten => 201,1,Dial(ZAP/G0/201|60|)

[incoming]
exten => 46004,1,Dial(SIP/201|60|)[/code] would do.

Thanks a lot !

This is just what I needed.
I looked in my zapata.conf and saw directly the relation to the extensions.conf file.

I insert the lines with some slight modifications and it works !!!

THX again !
