All of the suddent FreePBX (2.7.0.1) won’t let me create any new extensions.
I go to the Extensions tab, click to create a new extension. Step thru the “Add SIP Extension” form and at the bottom I click “Submit”. It takes me right back to the “Add an Extension” screen (as expected) and shows the list of extensions (about 50) on the right side…but the new one isn’t there. No “Apply configuration changes” prompt at the top either.
It’s as if the “Submit” button was just a “cancel” button. No errors, nothing.
I checked sip_additional.conf and sure enough my new extension doesn’t appear there either. Checked the permissions on sip_additional.conf. It’s owned by Asterisk and has 666 permissions.
We’ve rebooted the server (not always by choice - power outage) a couple of times in the last few days but the problem has persisted for at least a week.
Never mind…a little investigation revealed that we had a Ring Group with the same extension. Would be nice if FreePBX would have thrown some kind of error like “Extension Conflict” or “Extension already in use” rather than just silently failing. Would have set us about looking for that issue sooner.
Thanks for posting the solution! As blanchae predicted above, I just made the same mistake – 18 months after you did – and your post surely saved me some aggravation!
