Should be dialing as:
I thought about using:
... in the trunks dialling rules (I have 1234. going to one specific trunk in a defined outbound route). But I was unsure as to whether I could have a wildcard "." before the pipe "|".
My trunks are defined in Asterisk, but not all connected yet, and I need this one to work on one of the as-yet unconnected ones, so cant really test it right now.
Have I got it right?
