Busy tone when ringing internal extensions


This is normally a problem with analogue extensions as there is no display message that has DND status like a MLT handset, where the status is quite obvious.  This is mostly caused by users forgetting to dial 0 for an outside line & setting a DND / Call forwarding to an invalid destination.


Without going to system programming, you can tell just by going off hook on the analogue port & listening to the dial tone.

Instead of Dial tone:

Beeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeep…..


You get:

Beep , Beep , Beeeeeeeeeeeeeeeeeeeeeeep…..


System programming ( especially if you are remote ) can view handset status in 93-03, unfortunately this is READ ONLY. The example shows both a Call forward to an invalid number ( incomplete ) & a DND ALL set on extension 109.
