Need assistance or advice…
I would like to interface my old 56k dial up modem and a USB soundcard with RasPBX.
Will it be possible to use DAHDI or AGI to setup serial RS232 comms in order send AT commands to my dial up modem for PSTN call answering and number dailing.
The USB soundcard will obviously be used for audio.
Can anyone assist me with setup for RS232 and USB soundcard?
