The Countdown to Maker Faire Bay Area is On!


Outbound calling with Arduino + Asterisk


Dan Wagoner is playing around with connecting an Arduino to his Asterisk system.

I’ve been able to get Asterisk grab info about sensors connected to an ethernet-enabled Arduino, but how about the other way around? What if you could allow your Arduino to make outbound calls through your Asterisk system to make a make-shift alarm system, or over-powered doorbell? Well, wait no longer! Here’s how it works:

Asterisk: A php script lives on your Asterisk server (hosted up by apache) that, when it’s accessed, checks to make sure the client accessing it matches a pre-defined IP of your Arduino. If so, it creates a call file with the criteria that you configure to call a number of your choice and drops it in the Asterisk outgoing queue directory, triggering Asterisk to make a call.

    What about Audio okay you can send commands from phone to arduino but what about voice like audio calls from one arduino to another that is on the same network or different network i understand you need a server as the back bone but what about the Audio?

      Hey @Joseph, Did you managed to send audio?

    The volume is very low on your video, even at max volume.
