We need a developer specialized in Telecommunication and experienced in GSM termination.
We need to develop a software linked to a softswitch linked to real mobile phones (like Nokia or anything else) instead of GSM termination devices.
So when VoIP traffic is sent to the softswitch, it will find which phone is not busy and send the call to it.
We need to be able to completely control the phone through the system, from checking balance, to adding vouchers, and checking ussd and so on. Also the system should be having a CDR to know how many minutes were sent.
Please contact us only if you understand well the idea and able to it and ready to improve it, and you already have experience in the VOIP and Telecom field.
