Hey, We need a symbian app developed that works the following way: 1. App runs in background 2. When a call is made the call is stopped 3. A screen is displayed to the user including buttons ( 1,2,3,4 and #) 4. An mp3 is played to the user 5. After the mp3, an IVR is started with the user allowing them to press 1,2,3,4 or # 6. The call is connected 7. After the call; the call duration, number dialled and ivr data entered is sent to the server (in an xml packet) and mp3’s are downloaded onto the device based on the servers response. The details of the next mp3 to be played are also saved including mp3 filename and IVR details. 8. Once an hour, a server request that is almost identical to the after call server request is made to refresh the data on the device. all the interface design, server API, XML packet examples and IVR mp3s have been done and will be provided please give me a time and cost estimate on this. thank you
