Picking up a call during ring delay (Call Pickup)
You can pick up a call despite a ring delay (page 78) being set.
Requirements:
◆ The subscriber who picks up the call must have at least Incoming only authorisa-
tion (page 65).
◆ Both subscribers must be assigned the same receive MSN (page 72).

is signalled acoustically as well as being shown on the display on all handsets in this
MSN group. You can reject this external call.

Depending on the setting (page 74) the call is either only rejected on your own handset
(handsets with the same receive MSN continue to ring) or is rejected for the entire MSN
group (the caller hears the busy tone).
