Call managing application

Dear All, We are in need of a web application which captures incoming sms and retrieves the phone number within it to dial a call immediately. We have a city taxi office and we receive lead sms from JustDial. SMS we receive will contain the name and phone number of the customer to whom we should call immediately and provide them taxi service. Once we receive SMS fro JustDial, it should be received from our system and should immediately call the customer. First telephone operator will be speaking to the customer and he should be provided with a form to enter Name of the customer manually and submit it to store it in a database so that if the same number is dialed again, the corresponding customer name should be displayed on the screen. If we receive multiple sms at a time, the call should be made from the different phones managed by different teli callers. The caller will only speak to the customer and enters very few details like name, area of the customer and submits it. Rest of the things should be automated. I have attached a document containing a diagram to help you better understand the scenario. Remember, if the software is good and economical, t will be a continuous job for the programmer/company. Thank you
