Development of a call-through dialer App (Android & iOS)

We are a European Cloud Telephony Service Provider based in Belgium.

We would like to provide our customers having smartphones with a simple-to-use App that would allow them to choose a mode (private, business etc.). Depending on the mode, the App will then do nothing or overwrite the dialed number to place GSM outgoing calls through our platform.
