What is active station ringing set to on the station form/page 2?

 

[expack]

Active ringing option is set to "Single".

But as per my knowledge, making continuous it will ring continuously for second call on second call apperance while one is already in active state[inservice/offhook].

All the phones have similar settings on floor. But few agents facing this issue.
