We are having issue with calls being sent to the queue and it doesn't ring any available agents.

Initially, I had it to ring all simultaneously and occasionally (5-6 times a day), you will see call sits in the queue for more than 10 minutes and then eventually become abandoned.

I then have it set up queue as rotating and setup to transfer calls waited over 3 minutes to send to voice mail (rather than losing the call) but I can still find calls sits in the queue for over 3 minutes and then changed to abandoned after 4-5 minutes.

I have re-created the queue as support suggested and it doesn't help.

Does anyone have experience with losing calls in the call queue?
