FRITZ!Box 7390 – Service - Knowledge Base
Transmitting own telephone number (outgoing caller ID)
Your telephone number can be automatically transmitted when making calls. It is then shown in the telephone display of the person you are calling.
- Your telephony provider must have enabled Calling Line Identification Restriction (CLIR) on a call-by-call basis for your telephone line.
Note:The configuration procedure and notes on functions given in this guide refer to the latest FRITZ!OS for your FRITZ!Box.
- Enter #514*0*#91** on your telephone and press the call key (lift the receiver).
- Hang up again after about 3 seconds.
2 Transmitting outgoing caller ID when using call through
If you have configured "call through" in the FRITZ!Box and then use this function to make a call, your caller ID will not be transmitted automatically. However, you can transmit the telephone number of the telephone line that your FRITZ!Box is connected to on a call-by-call basis (only for one call):
- Dial the prefix #31# before entering the telephone number you would like to be routed to.
Important:The number of the telephone line you are calling the FRITZ!Box from cannot be transmitted.
