Maximum number of calls over the FRITZ!Box

The interface (for example DECT, LAN, FON 1, FON S0) and type of connection (Internet, analog, ISDN) limit the maximum number of calls that can be conducted over the FRITZ!Box. As a rule, you can conduct five calls over the Internet, an additional call over your analog landline, and two more calls over an ISDN line. Below you will find the exact number of calls possible with each type of interface. To find out how many calls you can conduct with your devices, you will have to calculate a little. We have given you a couple of calculation examples.

1 IP telephones

Two connections are established when you conduct an Internet call with an IP telephone configured for the "LAN/WAN" port: The internal connection between the IP telephone and the FRITZ!Box, and the connection to the external party. You can therefore conduct a maximum of two simultaneous Internet calls with IP telephones, and the number of possible calls is reduced.

Example:
If you conduct an Internet call with an IP telephone, three additional Internet calls can be made using the other interfaces.
If you conduct an Internet call with an IP telephone, and an IP telephone is being used to conduct a landline call, two additional Internet calls can be conducted with the other interfaces.
If two IP telephones are being used to conduct Internet calls, one additional Internet call can be conducted using the other interfaces.

2 DECT devices

You can conduct a maximum of three calls over your landline and/or the Internet at the same time using cordless telephones that are registered with the FRITZ!Box's DECT base station.

Example:
If Internet calls are being conducted with three cordless telephones and an IP telephone, you cannot conduct an additional Internet call using the other interfaces.

3 Analog devices

One call can be conducted with each of the analog devices connected to the "FON 1" or "FON 2" port.

4 ISDN devices

A maximum of two calls can be conducted over the landline and/or the Internet at the same time with ISDN devices connected to the "FON S0" port.

5 Integrated answering machine and fax function

The answering machine and the fax can each accept one call. All other callers hear a busy signal, even if you set up more than one answering machine. You cannot send a fax while receiving a fax, and you cannot receiving a fax while sending one.
