OBi Call Button Question

[azrobert]

The OBi Call Button only allows 11 digit numbers starting with "1", 10 digit numbers and 9 digit OBi numbers for single stage calling. Anything else I get error message "Did not recognize number".

An Example:
I have the OBiTalk InboundCallRoute setup to add an area code to a 7 digit number, but I still get the above error if I dial 7 digits.

Does anybody know how the OBi Call Button validates the dialed number?
