Conference Call System - Using Pilvo

Conference Call System (Plivo) The system needs to do the following When the participant calls, they are required to enter a 6 digit pin number (from a MYSQL Database) this pin should also become the conference call ID. Along side this pin should be chairpersons pin. So… I need … Caller connects … Enters Pin… If the are the chairperson they are asked to press * if not they are then asked to record their name. This recording will need to played back later. They should then enter the conference call and be placed on hold until the chairperson arrives. If * was pressed they are asked to enter the chairperson pin, This will then connect to chair to the conference call and open the call for everyone. As soon as the chair enters I need the above recordings for each caller to be played so the chair knows who is on the call. If anyone arrives after the chairperson it must also play there recording that they made when they dialled in. If someone hangs up or leaves the conference their recorded name must again be played so the chair knows they have left. The conference must also be recorded. However I need a variable in the php code to allow me to turn recording on or off at my leisure. Call details need to be saved into a simple call detail database. Should be a simple job for a Plivo coder please give me your best quote. The budget i have is very small. Regards Martin
