Our HX-series of handsets support CAT-iq 2.0 some even CAT-iq 2.1 for registering to Routers that are compatible to CAT-iq standard.
The CAT-iq standard offers high compatibility between devices from different manufacturers.
Synchronisation of date and time, Call lists and usage of the central router phonebook are just some of these comfort features.
For Fritzbox the minium firmware should bei higher than 7.0 to get best compatibility.
Mobile handsets with only an "H" in their name are generally only partially compatible with direct connection to a router. This may result in functional limitations such as no date and time synchronisation, no access to the router phone book or no call list. The name of your handset can be found on the back of the handset. If you have a belt clip installed, please remove it so that you can read the name.
