Hunt group ring timeout

[impiantitel]

I set the timeout time /System/Maximum ring duration → 30 seconds
and it's perfect for hair extensions.
The problem is that the above timeout is also used in the Hunt Groups.
30 seconds of ringing is too little, how do I increase the timeout time of the Hunt Group to more than 30 seconds and instead keep the timeout indicated above for the Extensions at 30 seconds?

You can add the same extensions again and again inside the Hunt Group to make it ring twice if not picked.

Unfortunately it is not so I tried, but still at 30 seconds the extension stops ringing even if I put the extension in more "stage".

Then set it to 25 secs twice then.

I've tried them out in every color. After 30 seconds, they stop ringing.

Alright, then the system won't allow the calls to go more than for 30 secs. You will have to set it to higher in that case.

[impiantitel]

ok but if I set it higher for example 90 seconds (I imagine the setting that shows me is that of the photo I set to 120 seconds), no longer used is the lack of response to an internal as it is very long.
Now I do some tests and I update you
