xs4all voip with Fritz!Box equipment: do not combine Fritz!Box “With prefix” number formats with xs4all “Block international numbers”: it will block non-international numbers too.

Posted by jpluimers on 2021/03/22

If you use xs4all VoIP from any Fritz!Box device, then keep the “Telephone Number Format” for “Country code” on “No”, and “Area code” to “None”:

If you have changed these to “With prefix” like I did:

combined with VoIP settings to block international numbers on the right, then when you dial a number outside your area, you will get a friendly voice telling you “this number is blocked”

On my research list: connecting Fritz!Box devices together into a virtual PBX

Posted by jpluimers on 2017/09/29

I’ve some Fritz!Box devices on various locations that each provide VoIP access and either ISDN or PSTN lines.

Wouldn’t it be cool to be able to join them together into a virtual PBX?

I’m not sure how it’s possible and what you need for it, so here are some links that should make my future research on this easier:
