WE have some users that turns off their phones when they are not at home.
We see the warning message:
Unable to create channel of type 'SIP' (cause 20 - Subscriber absent)
just after the Dial() command and a
Everyone is busy/congested at this time
Where is this "unable - cause 20" status available in the dialplan?
Which variable holds this?
We'd like to play something to the caller in case the user is absent.
