I'm wondering if there is a way I can make phone calls (not over the internet) from a Raspberry Pi product I'm developing (only make them, not receive them).

I thought on the following approaches, however couldn't find much information about them:

  • Some kind of paid service, that given a specific peripheral, I can make real phone calls.
  • Contact local communication companies to provide custom solutions.

Does anyone has any experience with the cellular networks and the Raspberry Pi?

From your post I deduct that you are looking for a cellular-based solution, not VoIP ( (not over the internet) ) nor land-line based ( Does anyone has any experience with thecellular networksand the Raspberry Pi?). If you did want to consider these you could look at using web.skype.com for Skype calls, or setting up PBX software on your rPi (Google for Asterisk PBX).

If you really want to do cellular, things are a bit tricky - but this stackexchange post might be of help. It is a bit old (2 years), however, it mentions that certain Huawei dongles might be able to do what you are looking for. The component it uses (chan_dongle) is located here, but is also 2 years old - so you would have to do some experimenting to check if it still works. Alternatively, as user ppumkin mentions in his accepted answer, you can run Asterisk PBX on the Pi and use a hardware GSM gateway to handle the cellular traffic for you. From what I can see those gateways are pretty expensive though (>$200).
