The trunk key 1 is occupied by your internal call number. Your internal call
number is assigned to an external call number where you can be reached
when being called from an external number. If you wish to make a call, lifting
the handset seizes the key (and the trunk line); you can immediately dial an
internal or external number (depending on the system setting). To call via a
certain trunk key (e. g.

It is possible to assign several external call numbers to a trunk key. A system
setting makes it also possible to have your internal number assigned to other
telephones as well. Calls will then be signalled to other telephones
simultaneously.
