At the moment I'm not using voxalot, mainly because my requirements aren't
sophisticated enough to warrant it. I think I did settle on the following dialplan:
(>#|*x.T|xx.T)
Maybe give that a try... I don't think the AC-211 was liking the [*x] syntax.
My NAT IP field is blank. I'm running the latest firmware, 4.6.22, from this page:
