Call Toggling
You can switch back and forth between different telephone conversations by using the R key. The inactive telephone conversation is maintained in the interim, and the other party cannot listen in. This additional service must be ena- bled for your telephone line (see Call Waiting, see Flash Key).
Call Waiting
If another caller places a call to you while you are having a telephone conversation, you will hear a tone. If additional services are enabled for your telephone connection, you can toggle back and forth between different telephone calls (see Flash Key; see Call Toggling).
Call-by-Call
Selection of the telephone service provider for each tele- phone call. It is possible to place telephone calls through different private service providers. By placing prefixes in front of the actual telephone number, one can choose a dif- ferent service provider for each telephone call without entering into a firm contract relationship.
Caller List
The numbers of the last callers are stored in the caller list. This function requires that the caller identification func- tion be enabled for your PTT line and that the caller not suppress the transmission of his or her telephone number (see Calling Line Identification).
Calling Line Identification (CLIP)
There are two types of Calling Line Identification Presen- tation (CLIP). If someone calls you, your device will show the caller’s telephone number on the display. If another caller places a call to you while you are having a telephone conversation, you will hear a tone. Your telephone com- pany must offer both services and must enable them for your PTT line. The transmission of your telephone number can be turned on and off temporarily or it can be turned off permanently (Calling Line Identification Restriction, CLIR).
