Crash was resolved this weekend by a code update via jira case - no more crashes after the update - some more dial plan edits and a little more testing I will be ready to head over to pay the Wiki tax
Thanks guys for adding this feature it seems to be working as expected and my 491 issues on the B-Leg / A-Leg have pretty much disappeared
