VoIP: passing on a phone number from one Fritz!Box to another Fritz!Box

Posted by jpluimers on 2024/03/11

Most Fritz!Box VoIP configurations have a phone number configured to only work on telephony devices (i.e. handsets) on the same Fritz!Box.

But it is possible to define a telephony device that itself is another VoIP end-point.

This way you can hook a second (or more) Fritz!Box up to the phone number(s) of the first Fritz!Box.

I am using this for two reasons:

Below is how to get this going, assuming the first Fritz!Box is a 7490 running firmware 7.29 and the second is a a 7360 with firmware 6.33 (other versions and firmware versions vary slightly).

But first the related post: Many links about free modem/router choice and their configurations for the Dutch KPN internet/VoIP provider where I figured out that just using a 7360 won’t cut it any more.

Many links about free modem/router choice and their configurations for the Dutch KPN internet/VoIP provider

Posted by jpluimers on 2024/02/19

I wrote this post because the xs4all->KPN transition was messy, especially on the VoIP side.

Emails and letters were incomplete lacking some essential information for manual configuration; 2nd line help desk did not return calls; pointers to where to find correct information were lacking.

This kind of is a catch all post with most of the links I found without much of their content so I can refer to them later when writing a more detailed post on how I did get VoIP to work.

So: for my link archive, almost all posts in Dutch.

Na migratie van XS4ALL naar KPN zijn al je telefoon-doorschakelingen weg: hoe dit te herstellen (spoiler: de on-line aanwijzingen kloppen niet)

Posted by jpluimers on 2022/09/02

In het kader van “kunnen dingen bij ons nooit eens normaal gaan?” het korte antwoord: nee.

Voorbeeld:

Voor de migratie van XS4ALL naar KPN hadden diverse telefoondoorschakelingen in gebruik (met name vertraagd doorschakelen: individuele nummers in ons huishouden gingen vertraagd door naar de bijbehorende mobiele nummers).

Na de migratie waren die allemaal weg. Het duurde even voor we daarachter waren omdat sinds de corona-periode vrijwel altijd iemand thuis is.

Kort en goed: we kamen er dus achter toen er niemand thuis was en we een opmerking kregen onbereikbaar te zijn (door iemand die ons mobiele nummer niet had).

Herstellen was ingewikkelder dan bedacht, want als je deze voor de hand liggende stappen van XS4ALL en KPN volgt kom je met een kluitje in het riet terecht:

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:
