Step by step
Picking up out-of-hours calls
If your switchboard is no longer attended after a certain
time, an out-of-hours call function can be configured on
one or more phones for this period.
For example, if you hear one of the phones that has an
out-of-hours call function configured ringing when the
office is closed, you can pick up the call early from your
phone.
You can also forward your phone to the phone with the
out-of-hours call function before leaving the office so
that colleagues who have not yet left can pick up calls
for you.

hours calls.
