Using second Fritzbox for Fon

[Sam Wardill]

My main router is a FRITZ!Box 7530 AX provided by Zen. I have a wired phone, a DECT phone and a FRITZ!App Fon registered with the box. I want to have a wired extension in my home office at the bottom of the garden. I have LAN to the home office and I have a phone there at the moment using a Linksys PAP with a sipgate number. I want to be able to call the home office phone from the house using the internal Fritzbox numbers.

I have a second FRITZ!Box 7530 KA from a legacy Zen connection. I was wondering if I could use that instead of the Linksys PAP and then get an internal FRITZ!Box number for the home office phone. Would that work? If not, is there another way?

Easy to do if you mesh your 7530 better per LAN (WLAN would be possible too) with your 7530-AX.

Then you get to option (under mesh) to provide phonebook and telephony to the other box.

When done you may register an DECT phone on the other box or use its fon-connector.

Just configuration to do so.

I use it since years like that for my parents nearby.

You can configure on each which number shall ring on which clients or connector.
Only there is no DECT-roaming, so your DECT phone may be registered to either one or the other box.
You probably (depending on phone) can register it to both boxes, but only one is active and you have to change it to the other one if you leave the supply range of the DECT.

All used phone numbers have to be registred on the master box and are available on mesh-client too.

BTW: There is no 7530-KA, its an 7530, KA is only an identification code not part of the model number whereas 7590-AX is a different model (with AX-Wifi).

Thanks. Will give this a shot. I’m not actually using my Fritzbox for wifi. I have a Deco for wifi. However, I guess this doesn’t stop me meshing the Fritzbox for telephony.

You can use it without wifi too, but than you need to use LAN backhaul between boxes.
