Sip member ring and stop ring in queue

Dear
I have a problem with my queue.
When there is a caller in queue all sip member start to ring, but only for one minutes, then it stops to ring for few seconds and after it starts to ring again, and on my phone i see for example “one missing call”.
How i can set it ring until one sip member pick up the call?
thank you

Set timeout, for the queue, to be a very large number. Note that this will mean that a member coming free, after the start, will never be eligible to answer the call, unless all the others actively reject it.

The time it rings is timeout, and the quiet time is retry.
