Over the past year, I have cobbled together a set of personal notes on how DigitMaps are used to route outgoing calls. While trying to coalesce them into one document recently, I decided to expand on it a bit and offer the results to all OBi owners in the hopes it might assist them in understanding this part of their OBi's operations.
This is not a first-read document. It presumes you have at least read the OBi Device Admin Guide chapter on "Digit Map Configuration" and know what the various DigitMaps represent. It mainly walks you through the details of how outbound validation and routing is done on the modern OBi devices.
If you find it helpful, well, great. That was the intent. And, if you find errors in the document, let me know so that we can get them corrected.
The document can be found here:

Enjoy,
Rob
