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:

KPN CPS (carrier pre select) code is 1655

Posted by jpluimers on 2017/09/26

Since the CPS I used was increasing the subscription cost to above zero, the the price difference to KPN was too large, so I wanted to switch back and needed the KPN CPS code.

From [WayBackHet verschil tussen WLR en CPS I found out the CPS code for KPN is 1655.

Then I called 0800-1273 to set it back and then verified it was set back for all destinations on all ISDN numbers.

It’s time to research how to move away from ISDN anyway, but that’s a different story.

GSM/3G/4G/LTE/… enable or disable caller ID when calling

Posted by jpluimers on 2017/02/13

When testing the setup of a Fritz!Box 7490 with fiber connection, routing anonymous/withheld ISDN calls to a new answering machine I needed to test if only Caller ID calls were getting through.

The easiest was to do this from my mobile phone.

Izzy explained how to in callerid – How can I make anonymous calls for everyone but contact list? – Android Enthusiasts Stack Exchange.

Basically all cellular networks based on GSM or derived technologies allow you to prefix any phone numbers with:
