Hello,
I’m trying to extend our infrastructure with Asterisk VoiP.
'Till now we only use an Auerswald COMmander to establish phone calls via ISDN.
The images shows what I would like to build:

- Calls from Phone 1 to Phone 2 should be handeld by Auerswald
- Calls from Phone 3 to Phone 4 should be handeld by Asterisk
Is it possible to make call from Phone 3 to Phone 1 or
call from Phone 3 to the World
and the other way round?
So as I dial a 4 digit number like 1XXX I can make internal office calls via VoiP
and as I dial 2 digit numbers (sth btw 10 and 99) internal office calls to “normal” isdn phones
no matter which phone I use.
Can someone please help me?
Thanks,
Lono
