COLP (Connected Line Identification Presentation)
User A calls User B. B's phone number is displayed on A's telephone. If, for example,
B has programmed call forwarding to C, and the dialled number and transmitted
number are not the same, then C's phone number is displayed if C permits this
phone number to be displayed.
COLR (Connected Line Identification Restriction)
If C has set up COLR, then C's phone number is not displayed on A's phone.

Direct call
Block the telephone for all phone numbers except for an individually entered
number. After picking up the handset and pressing any key, the connection to the
saved phone number is established. Ideal for children who cannot yet dial phone
numbers (baby call). Calling an emergency number is always possible. This function
is available on the Gigaset 3000/2000 Comfort handsets.

Electronic code lock
Personal code (=> PIN), used, for example, to protect a phone against unauthorised
use – only calls to emergency numbers may still be made. Incoming calls may be
answered.
Enquiry call
You are making a call. Using the "Enquiry call" function, you interrupt the
conversation briefly to establish a second internal or external connection to another
user. If you terminate the connection to this user immediately, then this was an
enquiry call. If you switch to and fro between the first and second user, it is called
toggling.
Exchange
Nodal point in the public telephone network. A distinction is made, for example,
between local exchanges and long-distance or trunk exchanges.
