I am building an applicaiton that needs to answer an incoming phone call, play a .wav file to the caller, capture the caller id, generate an event for a vb app and then send a text message back to the user.
We are currently using a TAPI interface with a regular phone line, but I assume there is a better way uisng VOIP and a soft PBX. Can you suggest some good solutions for;
- Windows based free soft PBX (I assume this is what i need to answer the calls)
- I assume I need a IP phone service that gives me a phone number, routes the calls to my app and sends me the caller id. Can you suggest a good and low cost solution?
- Any other good sample applicaitons that would show me the ropes would be helpful.
