Build a VoIP/SMPP/PBX SMS Gateway

I am looking to create a SMS Gateway service that utilizes either PBX, SMPP, or VoIP - the platform must be able to run stand-alone meaning it can not use any 3rd party services such as a 3rd party sip provider, a 3rd party SMS service such as Twilio or Plivo. It must not need SIM Cards or modems.

It must be able to create VoIP numbers (on it's own) ex; not using Google Voice or anything like that.

It must be able to send and receive SMS messages from a standard cell phone.

The overall price is negotiable as long as the system you build works on it's own and is proven to work.

If you are serious about taking on this project and completely understand what I am looking for, in your initial message please type "I understand, No Twilio No Plivo" - otherwise your message / application will be rejected. I am NOT looking for any sort of automated bidders on this project and please only bid if you understand what I am looking for.
