Is it possible to keep the caller in line until he is answered?

Question

Asterisk

Good day! The question is, is it possible to somehow keep the caller even if, when calling, everyone in the queue hung up. I began to notice that a lot of calls with the status are busy, I suspect that 2 operators in the queue beat off the call and it goes to busy. Is it possible to somehow keep the caller in the queue until he is answered, even if the operators reject him,

Answer 1

To remove a call from the queue, the operator must accept it. While no one has accepted the call, it will hang in the queue until the timeout.
