Don't want voicemail just want to limit rings it rings like 20 times

[AC Question]

I can't set up voicemail cause I work public where it would be full 24/7 just want to limit the amount of times my s4 rings it's like 20 times before it stops!

Hi, the only way I know to do this is to set a custom ringtone that only lasts about 10 seconds - once the ringtone is done the call is done.
