4.5 Answer-back (ANSWR)
With the answer-back feature you can reply to incoming calls from sources not assigned
to keys on your I-Series panel. You can also call out to destinations not assigned to keys
on your panel.
Tip: The answer-back feature is known as the Reply key on V-Series panels.
If a second unassigned source calls you while you are speaking to the first unassigned
source, the second call is placed in the answer-back stack, a group of up to eight waiting
calls that are answered in sequence.
All incoming calls can be answered at the answer-back keys, whether from sources with
assigned keys on the intercom panel or from sources without assigned keys. Typically,
however, only calls from sources without assigned keys are answered there.
The following sections describe how to use the answer-back feature.
