I'm using a Fritz 7490 currently on 2D UFB with landline (over VOIP). Settling into a new home soon which is all wired up in each room, but the router sits in the garage and so the WiFi doesn't reach everywhere for mobiles etc.

Just reading around, thinking of upgrading to the GWN7000 and 1 (or 2 if needed) GWN7610 AP's for the internet. What to do about the phone line? Is it possible to get it working on 2D with this setup?

I don't actually use the landline but family loves the phone number and doesn't wanna lose it hence keeping it -_-

I know the common suggestion is to go with 2Talk but is this the only option? Also what other hardware would be required to get 2Talk working? Just an ATA adapter or would I need to change phones? We've only got Panasonic KXTG2723 phones right now with the fritz.
Cheers in advance for any help.
