I guess I was a little confused about what this actually does. This does not do any calling, right? It just issues a command to Plivo to call Mom's number and then, when she answers, call a second number (assuming this to be the house where this device is located). At that point the RasPi is totally out of picture as the conversation happens phone-to-phone (possibly getting Plivo out of the picture too?). So you've created an external one-touch speed dial. Is that accurate? Side note: Is there something that prevents me from building this and putting in two numbers I am not associated with? Push button. Two random strangers get calls from each other. Hilarity ensues. That type of thing is kind of scary.

I haven't used Plivo, but IIRC, with Twilio, you had to verify you owned the number you used in the Caller ID field, either by buying a DID from them or by entering a confirmation code sent to that number via a call and/or SMS.

  Hi chhl. With Plivo, you also need to get legitimate numbers to send SMS messages. (numbers purchased on Plivo or numbers ported to Plivo) As you know, this is a preventive measure against spoofing; however there are some edge cases where allowing custom caller IDs might make sense. (e.g. when you want to have people you called get back to a certain number—custom phone line numbers at a large organization.)

    That all makes sense. I assumed there would be some safe guards for that very reason.

      True, I think that's fair concern.

Hi, you're correct that the RasPi functions as a quick dialer and is out of picture once the call is answered, as the original set-up doesn't have the ability to receive a call. *this could be virtually any connected device; mobile, fixed phone or SIP phones. Also you could do a lot more fun stuff using conferencing or anything that's on our xml page: http://plivo.com/docs/xml/ http://plivo.com/docs/xml/
