Functions and features that can be used with cordless telephones
The FRITZ!Box supports the DECT standard and the DECT-GAP profile. The DECT-GAP profile allows DECT devices from different manufacturers to communicate with each other. The FRITZ!Box allows you to use all of the functions defined in this profile, as well as additional ones. Which functions can be used in addition to the ones covered by DECT-GAP depends on the telephone's manufacturer.
Gigaset compiled a compatibility list; you can use it to check which functions can be used with different Gigaset devices.

2 Functions you may be able to use
CLIP can often be used
CLIP is a function for incoming calls. If callers transmit their telephone numbers, their numbers are shown on the telephone's display when they call. CLIP can be used with all FRITZ!Fons and many Gigaset devices. However, AVM cannot guarantee that CLIP will work with telephones from other manufacturers.
DECT Eco is rarely available
With DECT Eco, the DECT field is switched off completely as soon as all of the cordless telephones are in standby mode. DECT Eco can only be used if all of the cordless telephones registered with the FRITZ!Box support DECT Eco. Besides the FRITZ!Fon, some telephones from other manufacturers also support this function. However, AVM cannot guarantee that DECT Eco will work with telephones from other manufacturers.
3 Additional functions that can be used in combination with FRITZ!Fon

- The telephone indicates missed calls.

- Calls can be establish directly from the call list or the FRITZ!Box's telephone book.

- In the "Telephony > Own telephone no." menu, you can specify a different number for the next outgoing call.
