my router, my phones, ...

My router is not just a router. To the inside world it lets me also attach phones and esp. also DECT wireless phones. To the outside world it connect also to my SIP (VoIP) account and the telephone network. I registered all my DECT wireless phones to my router, and I got rid of all the wired phones. Just my fax stays connected to my router, so I can send out faxes once in a while. Incoming faxes get converted to PDF by some provider. My current router, that can do all that and much more, is a FRITZ!Box 7270.
