Leave the Overflow destination blank. You only need one apology greeting during a 60 second call. A 5 to 10 second greeting repeated every 15 seconds is more than a little obnoxious.

The Recall destination needs to be a CRA that times out to a mailbox. If you recall to the VM application, your caller will hear “Welcome to the Inter-Tel voice processing system. Please enter a mailbox number”.

I would never program a hunt group as you describe; it’s just plain crappy workflow. The phone rings twice, then the call disappears just as the agent is reaching for the phone. That is repeated amongst several agents, then the calls dumps into voice mail after only a minute.

Someone now has to be tasked to listen to the message, and then play phone tag with the caller. Instead of properly routing the call and servicing the customer the first time, you waste time and money chasing them. But hey, what do I know?
