[asterisk-users] how to activate DND on 1.6.0.9

[Oguzhan Kayhan]

Hi,
I want to activate DND on ast 1.6.0.9 with asterisk-gui.

Is there special commands that i need to use during such script
or simply writing a code in extensions.conf that checks if the user has a
DND=yes value on ast. database and act according to that like forwarding
call to voicemail or sending back a busy tone or playing a DND msg.

And is there a way to notify a GPX_2000 for example for a DND status of
another client??
