Hello,
I have the full version of fop2 installed and working however I wanted to display the DND status on my fop so I installed fop2beta. The installation went well and everything works except I am still not getting DND status to transfer. I have added the extensions_override to the ./etc/asterisk however alhough I can see the phone dialing *78 once that is done nothing gets updated. Below are my configs, any help is appreciated
/etc/asterisk/extensons_override_freepbx.conf

I am using the sample FOP2Callbacks.pm

Anything else I need to do?

I am running Debian
With asterisk 1.6 with FreePBX
I am not sure what you mean by the user's permission. But I gave the manager account full rights, and the buttons are auto-generated along with the users from the FreePBX script.

This is what my manger.conf looks like

[administrator]
secret = *************************
deny=0.0.0.0/0.0.0.0
permit=127.0.0.1/255.255.255.0
;read = system,call,log,verbose,command,agent,user
;write = system,call,log,verbose,command,agent,user
read =all
write=all

That's the same account I use in fop2.cfg

I am using the latest beta with the extension override.
