Parking Lot

Good day,

I have a set of phones that use the Parking lot. It work fine.

If the call is not answered in 60 seconds, it ring back to the original phone who parked it…

But… if nobody answer, after 3 ring, the line terminate…

But, if I call to that extension, it will ring forever… what can I change for the parked call to ring indefinitely when coming back to the original extension ?
