Well, that is good news. Would you mind posting what your freepbx page for that extension looks like in 7.10?
I'm starting to think it is a freepbx problem because when I go in and try to add an extension manually, on submit, I get:
"Error: Trying to write null voicemail file! I refuse to contiune!"
Googling this suggests that this is a bug in one of the updates:http://www.trixbox.org/forums/trixbox-forums/help/problems-creating-extension
This would suggest that when the script tries to add the 7970 as an asterisk extension it hits an error that is undetected on the UI and just dies.
I am using:
FreePBX 2.2.0beta3 on 192.168.80.1
Which freepbx are you/should I be using in 710? Perhaps I upgraded freepbx when I shouldn't have? I remember there were alerts to upgrade some time ago within the interface. If so, is there any way to roll back to the version I should be using from within the files in linuxmce or elsewhere?
If this is the problem, it would be good to share it with the other unsuspecting upgraders out there.
Again, many thanks to everyone for their input.
