This past holiday weekend has resulted in some real groaners when it comes to bugs in our dialplan, making obvious the need for some changes in our procedures.
First, our hours of operation for Christmas Eve, Christmas, Boxing Day and New Year’s Eve had changed with little to no notice. Okay, fine, whatever, I fix.
Our Christmas Eve hours (made worse by being Monday this year) dialplan was broken by me misspelling the correct dialplan to go to. Then our Boxing Day dialplan was broken when I copied and pasted the correct dialplan from one similar extension number to the other, like this:
; exten =>
then failed to notice the problem until it was too late. Of course, that only applied on Boxing day and couldn’t be noticed earlier, either.
I suppose the first problem where I misspelt the dialplan can be solved by testing the dialplan in another extension and modifying the time to
“now + 2 minutes”. But how can I avoid stupid errors in the extension number, when testing by definition requires that I change the extension number to and fro?
This appears to boil down to “always remember to test it at the time that it becomes relevant”. But if I was the kind of person who always remembered to do things at the right time, then there would never be a need for computers to do jobs like this in the first place.
