I have an analog phone which connected to an FXS Digium card.
Follow the tutorial of Hotline Dial, I can see the Asterisk detect off-hook action from the analog phone through Asterisk CLI.
But then nothing happens.
I’m using FreePBX 14 (SNG7-PBX-64bit-1805-1).
Not sure if I missing something or the analog phone is not supportable.
IIRC, the tutorial assumes your hotline phone is going to dial. If you don’t have a dialer or want to override the dialer, you should use a custom context to send to call to some other destination. For example, I set up emergency phones in waiting rooms that are tied to a custom context that just dials a ring group, which then answers the phone.
