Copied a rule from my regex edit into Company_Phone_Number_Normalization_Rules.txt and it dit not work.
ABServer.exe -testphonenorm could not find any match even tho it told me it was using my rules (according to abserver.exe -dumprules).
Turned out there was one or more spaces at the end of the line. ARG!!!
“^(\d{8})$ ” <—— NO!
