There is a German and an international (English) version, and there are three hardware 
versions with slightly different features. In Germany ISDN is typically Annex B, but 
supposedly it is not so difficult to modify the box for Annex A.

The built-in SIP proxy is made for "inside LAN" usage, although there are ways to make the 
box also accept SIP UAs on the Internet as local "phones". Do not expect too many features 
for these IP phones, for example AVM only very recently added transfer capability. Telnet 
access can be enabled by DTMF (Linux inside), and there is an unsupported mod system 
called "Freetz" that permits to install Asterisk and other tools.

BTW, the successor to the very popular 7270 is the 7390 (VDSL, Gigabit switch).
