Phone keeps ringing if unanswered in call queue

[Reflexsystems]

Hello,

I've configured a call queue whicht contains 6 phones.
If a call comes in, all 6 phones are ringing = ok

But, if the call is answered by one of the phones, there is still one phone who keeps ringing ?

I have the same problem when I use a ring group.

3CX Version 8.0.101.116.583
