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