We are looking to develop an auto VOIP dialer for phone numbers verification purpose. The dialer should make a call to each phone number and if the call status was ringing or busy then this number is valid ( Dialer should hang up before call is answered ). If the call did not go through then the number is not valid.
- Import list of phone numbers.
- Rotate VOIP accounts from different providers.
- Export report ( CSV file that contains 2 columns phone number and status )
It is not required to build the solution from scratch up, we do not mind using an open source framework and build our solution on top of that. Also the programming language is not an issue. What is really important for us is the performance.
