Hi Grant,
I think that you have spotted a genuine firmware design error. I have just checked my OBi1032 and have the same default BT digitmap:
(1xxxxxxxxxx|011xx.|[1-9]11S2|[1-9]xx)
The final rule makes no sense without the "."
Personally, I would have preferred to see this as the default:
(1xxxxxxxxxx|011xx.|[1-9]11S2|xx.)
This would enable users outside of North America to get some sort of service using the BT Voice Service while they were thinking about a digit map more suited to their needs.
Edit: Looking at Lavarock7's post, this seems to only be a problem with the OBi1032 and not for the OBi1062.
