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.
