Beginner here. After failing to compile/install an Asterisk server trying multiple linux distros, versions of dahdi, and versions of Asterisk, 10.13.66-21 of FreePBX installed, ran, and recognized my Atcom AXE400P-20 with two FXSs the first time! Yay!
Now my problem is no dial tone. Do I need an FXO for Asterisk to generate one, or can I configure the system for internal use only generating a dial tone without an outgoing line? Where in the documentation should I start? I just want two vintage pots modems (think Winmodem/ USR Sportsters) hooked up to vintage computers to dial each other using extensions.
