Update:
So I've played around a little bit, and got my SplitInfinity VoIP with dedicated number now working with this baby:
Link to the Box
It's an all in one Box for: VoIP, DSL, WLAN, Phone-management.
Basicly I have one wireless phone and a fax attached to this box and 4 numbers routed to the phone, 1 to the fax... 3 of those numbers are VoIP, 1 is my landline.
Comes in quite handy cause I don't need another phone or the soft-phone either.
Pretty cool to if you ask me
P.S.: Thanx to Chris again for taking time and monitoring as I was playing around with the setup of the SplitInfinity VoIP number in the Fritz.Box
