on my note 4, i set the ringtone to beep once. now when i get a call it keeps beeping like beep ...... beep ..... beep ...... beep ...... i only want it to beep once and stop.
The factory beep ring tone just works that way. It's set to repeat for the duration of the phone call. You may want to look at Zedge or similar for a ring tone that only beeps once. Good luck mate.
