Many support questions arise about Digit Maps.
The Obi devices themselves don't give a lot of help with diagnosing / testing these.
How about an online debugger?
This would allow you to load your backup configuration, edit the various maps, and run through a saved set of test cases to see what is routed where with what caller information etc.
Example test cases and digit maps could be provided for various scenarios.
The test cases should be able to specify the number dialled on the PHONE port, and what corresponding number should be dialled on LINE/SP1/SP2/.... , or whether the number should be rejected.
Ideally it would be possible to download the edited configuration file (perhaps with the user having to re-enter usernames and passwords to prevent security problems from storing this information at the Obi end). (Possibly the Obi device allows loading of a partial configuration, in which case only the DigitMap/OutboundCallRoute etc. need be stored / included.
Alternatively it could just be made simple to copy/paste the Digit Maps into an Obi setup, although this would increase the risk of user error.
