Hi all
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
message.
Where is this unable - cause 20 status available in the dialplan?
This means the SIP endpoint is defined in sip.conf, but no device is
registered; which is consistent with phones being turned off.
Which variable holds this?
We'd like to play something to the caller in case the user is absent.
It should be ${HANGUPCAUSE} . So you can use something like
Gotoif($[${HANGUPCAUSE}=20]?subs_absent)
in your dialplan, and it will go to the label (subs_absent) if the Dial()
fails for cause 20 - Subscriber Absent. Then you can play a recorded
announcement, or send them to voicemail.
