I need a custom app designed for both Android and iPhone. iPhone version should also be scalable for use on iPad with VOIP app (like Talkatone) installed. Android version should also be scalable for use on Android tablets with VOIP app (like GrooveIP)
App must launch when an incoming phone call is detected from specified telephone number(s).
When incoming call is detected from specified telephone number, it will launch an expandable overlay to the native phone app (similar to the Android app "Current Caller ID". The overlay will display a designated line of text, as well as a small image in the upper left corner. .
Once the call is answered, the overlay should expand automatically to full screen. The expanded area will include an iframed/embedded live IP camera feed, as well as two control buttons. One button will end the call and close the app window, and a second button will be configured to send a specified DTMF (touch tone code) after two presses (FIRST PRESS to launch a "Are you sure? Press again to confirm" message. SECOND PRESS to actually send the DTMF (touch tone code).
The app should also have some logging features, such as logging the date/time of each incoming call from the specified number. The app will pull 4 pieces of data from an admin website/database: 1) The incoming telephone number that will launch the app 2) The IP address of the IP cam to be displayed in the overlay 3) A text string for the top of the overlay 4) The URL for a small image to be displayed in the overlay.
Lastly, I understand the iOS has an API limitation that an app cannot sleep and be launched upon action of an incoming phone call. If this API limitation cannot be worked around, then the iPhone version of this app may need to use a push notification (with user acceptance) to launch an inbound VOIP call. I will rely on the expertise of the selected developer to determine the best course of implementing this functionality on the iPhone platform.
