Note: Only one function or call number can be programmed for
each call key.
The following keys can be used:
z Trunk key: Calls (for the programmed call number, e.g. 11)
are signalled to this key, and you can make internal and
external calls via this number. A trunk key can be programmed
with a substitute function (with another team member acting
as the substitute). Calls for you are then signalled to the
terminal of another team member. A trunk key also provides
functions for managing calls. For example, you can configure
call protection if you do not want to be disturbed, or call
diversion to another telephone.
z Team key: As with a trunk key, a team key can be used to
receive or make calls. However, this key cannot be used to
change the settings for managing calls; it is not possible, for
example, to configure call diversion to another telephone. Calls
made via a team key are signalled to all terminals with a trunk
key that has been programmed with the same number. For
example, the team key with the number 11 calls all trunk keys
with the number 11.
z Direct call key: Only outgoing calls can be made with a direct
call key; they are signalled to all terminals with the same
number programmed to a trunk key. Calls via a direct call key
are signalled to the destination terminal even if that terminal
