<div>Your Dialplan there will dial the first line for a maximum of 2 seconds. I'm not even sure if they'll hear it ring. I'd rather call all lines for something like 30 seconds but stagger the calls a few seconds apart to make sure the people who should be answering the calls have a better oportunity to do so.

<div>But your dialplan isn't horribe. It's what I want, but without hanging up and dialing again. If just it would keep SIP/1 in your example active the entire time. Also, for me this is a PSTN non-local network so it requires the long wait time between the 10 digit phone number being dialed and the agent picking up the phone.
