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:

Siemens GigaSet DX600A TCP port 650 protocol looks like old-school AT commands…

Posted by jpluimers on 2017/09/29

While playing around with nmap to view some of my IoT^w LoT devices, I found out my Siemens GigaSet DX600A ISDN (yes: ISDN; I’m an old fart) has these two ports open:

PORT    STATE SERVICE VERSION
80/tcp  open  http    Siemens Gigaset A580, DX800A, or S450 VoIP phone http config
| http-methods: 
|_  Supported Methods: GET POST
|_http-server-header: 
| http-title: Site doesn't have a title (text/html).
|_Requested resource was http://dx600a-isdn.pso71.local/login.html
650/tcp open  telnet  Gigaset telnetd
MAC Address: 7C:2F:80:15:D6:10 (Gigaset Communications GmbH)
Device type: general purpose
Running: Linux 2.6.X
OS CPE: cpe:/o:linux:linux_kernel:2.6
OS details: Linux 2.6.13 - 2.6.32

I’m going to play with port 650 later as it looks like it supports an AT command protocol(on Windows the GigaSet QuickSync TAPI driver translates TAPI to AT commands) so it should be possible to do all kinds of cool stuff with it.

These links should help ans it should work with the DX800A as well:
