God, I LOVE things like this - Awesome! I have done 3 boxes this morning!
Glad you like it!
This is the kind of beautiful utility-programming that I always aspire to emulate - Yes, you can convert the extensions manually through the GUI, but that is TEDIOUS!
Being that I have “Drunk The Kool-Aid” and am in the process of switching all my boxes over to pure PJSIP, you can not imagine how much time this saves - or maybe you can which is why you wrote it!
Either way, Bravo!
