I have been testing a customers configuration on V11, the original was done in V9 and then updated to V10. In the setup a few ring groups have been set up to provide a number users can dial to call a number of extensions, these are four digit numbers. However in V11 you are prevented from using more digits than a standard extension, in this case three. If I try to change the extensions in the ring group now I am forced to either change the ring group number to a three digit number or abandon the changes. So long as I don't adjust the group the four digit numbers still work fine. I can see why the change has been introduced, for me its a real pain in arse. Does anyone know work round I might use, editing the ring group outside the standard 3CX interface in a settings file or the registry may be.
