I want to establish a voice call between softphone application and analogue phone, through asterisk and ProSLIC interface. I have Asterisk running on Raspberry PI zero which is connected to ProSLIC custom board through PCM interface. Telephone is connected to ProSLIC with an analogue phone connector.
In these set up, I am not able to get any information on how to interface Asterisk to ProSLIC API s. I would be grateful for any suggestions. Or any other references related to this issue.
Hi Michael, this isn’t a direct answer to your question, still you might be interested to look at https://switchpi.com/ for an FXO/FXS interfaced to Raspberry Pi? I got this running on an RPi4B recently. It uses DAHDI as the glue layer between Asterisk and the RPi GPIOs.
