Click to call

I WANT TO DEVELOP A CLICK TO CALL SERVER Functionality: Caller will see a website which has " contact Us" button and caller will press the button. As soon as he presses the button, Caller receives the call from our server. If the caller picks up the call, the server attempts the receivers number ( It can be mobile number or a land line number) and as soon as the receiver pick up the call, the caller and receiver gets connected. now they can chat. Requirement( basic) a> API through which i will send the two phone no.s and the avialable balance of the caller along with the callers login id. and on disconnection of the call my database will be updated with the new caller balance. and talked duration b> Details of the call logs c> check the monthly minutes consumption with a area wise consumption search. d> Panel to change the details of the VOIP provider, if i want to change the voip provider. e> Need Real time info about the initiation of the calls from the server f> Need real time info about call Connection/disconnection g> need button to disconnect the ongoing calls. To be more precise: 1. Caller's Call INITIATE time and date 2. If CONNECTED: connection date and time 3. if NOT CONNECTED: reason for not connection, date,time( optional) 4.. Callee's Call INITIATE time and date 5. If CONNECTED: connection date and time 6. if NOT CONNECTED: reason for not connection, date,time( optional) 7. if connected, After CALL TERMINATED , termination date and time. Database: We will do the database design with your inputs and suggestions Click to call server will be one but the quiery could come from different websites with different balances. There should be a option for unlimited balance also, if I want to assign to any client or website.
