We would like to have Raspberry Pi function as an analog phone and create a system that automatically makes phone calls.
Could someone please let me know if there are any related documents or URLs that might be helpful?
Of course, we are thinking of acquiring the technology as soon as it is realized.
Thank you for your cooperation.
Why don't you tap the contact point of the button part of the analog phone (pushphone, etc.) on the market from Raspberry Pi?
I think it's easy to use a relay.
If you want to communicate, I think you can do AD and DA, so I think you should check the circuits of the phones on the market first.
You can connect a voice modem to a raspie.
Well, the point might be whether you can get a driver for that raspy.
Asterisk allows you to build a free digital private telephone exchange (PBX) and other hardware requires VoIP adapters around Grandstream, but the current HT802 will cost less than 10,000 yen.
Domestic information is available in VoIP-Info.jp Wiki, as well as commentary, summary site and Raspberry Pi examples.
I think you can still get an interface called an analog modem (modem terminal adapter).
You can make a call with the AT command.
