I'm finding that http://www.3cx.com/blog/docs/bulk-extension-import/ shows VMNoPin with incorrect values.. the results are backwards. I ran "0" for these extensions.. tested "999" on a newly provisioned Yealink.. wasn't greeted with a PIN but instead was informed I had no voicemails. Looked at the registered extension.. the option do disable vm PIN auth was checked. So.. I killed all the extensions I had not yet provisioned the handsets to (passwords..), updated that setting for the three our four handsets I spot-provisioned.. changed VMNoPin to "1" down the column.. imported again. It skipped the existing extensions as expected.. all the replacements imported now have that option unchecked. Can somebody update that page.. and perhaps update the field name and/or values for v13? I'm doing 50 extensions.. would suck to see it after the fact and have to work things over manually after a rollout.
