About RingCode
If the normal ringtones are silenced, the application will notify incoming calls
with a Morse code associated with the calling number.
The user assigns codes to phone numbers (either directly or based on contact
info). The list of assignments can be modified (entry activated, deactivated or
deleted).
The user can specify parameters like volume and Morse speed.
