Why? I would immediately switch to another manufacturer:
1. The FB 7270 is not half as fast as a Netgear modem - it also comes nowhere near to its Geschwindignkeitsbereiche.
2. In spite of regular disruptions - and the need to maximum reset (off for 20 seconds) every 2 days - the unit runs fairly - you can not just rely on ...
I have partly filled with the latest software updates - everything works very well.
The Fritz-fax-Beta is a recommendation - never was FAXES Forwarding easier.
Voice mail and fax reception with transmission by e-mail are great solved and easy to install - well of the adjustment aids.
A big minus is the text meeting the answering machine: It's actually only directly by phone. The seemingly simple way to install a file, for example, music and text, extreme hobbyist pages supplies online: Using special programs, the file must be converted and adapted - to be uploaded to a hard-to-find location with special programs! Since AVM must urgently rework.
With the DECT Drahnlos phone reception can be satisfied - even the coverage is not too bad (compared with Siemens appliances).
If you have the expert mode finally discovered yet, you can also make special settings - for example, easily change the IP addresses, which are denied to the normal user.
Lovely, too, that all the settings of the device software can be easily made via the Internet Explorer. And after call come via email - a super comfort.
So: There are many reasons for a recommendation - but with a bad sense of reliability and speed.
