Maximum number of calls over the FRITZ!Box
The maximum number of calls that can be conducted over the FRITZ!Box is limited by the interface (for example DECT, LAN, FON 1) and respective type of connection (internet, analog). You can conduct five calls over the internet and an additional call from your analog landline. 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 must do a little calculating. We have given you a couple of calculation examples.
1 IP telephones
Two connections are established when making internet calls with an IP telephone that is configured for the "LAN/WAN" port. Therefore, you can conduct a maximum of two internet calls at the same time with IP telephones, and the number of possible calls is reduced.
If you conduct an internet call with an IP telephone, three additional internet calls can be made using the other interfaces.
If an IP telephone is being used to conduct an internet call and another IP telephone is used for 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 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 cannot conduct an additional internet call using the other interfaces.
3 Analog devices
You can conduct one call with an analog device connected to the socket "FON".
4 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.
