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. You can conduct six calls over the internet, an additional call from an analog landline, and two more calls from an ISDN line. Below you will find the 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 three simultaneous internet calls with IP telephones, and the number of possible calls is reduced.
If you conduct an internet call with an IP telephone, and an IP telephone is being used to conduct a landline call, three additional internet calls can be conducted with the other interfaces.
If two IP telephones are being used to conduct internet calls, two additional internet calls can be conducted using the other interfaces.
If three IP telephones are being used to conduct internet calls, no additional internet call can be conducted using the other interfaces.
2 DECT devices
You can conduct a maximum of three calls from your landline and/or over the internet at the same time using cordless telephones that are registered with the FRITZ!Box's DECT base station.
If internet calls are being conducted with three cordless telephones and an IP telephone, you can conduct an additional internet call using the other interfaces. You cannot conduct an additional call with an IP telephone.
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 from 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.
