A while ago, I documented some links for In case I ever need to record calls on my Fritz!Box devices.
By now, I’ve done a bit more investigation: I’ve enabled the call monitor, did some port scans, installed domoticz and got deeper into fritzcap.
Oh and I got packet capturing to work too: Fritz!Box – capture network packets in Wireshark format or ISDN in dtrace format.
A small recap so I don’t forget what I did and what the effects were.
[WayBack] Fritzbox – Domoticz showed how to enable the CallMonitor option in your Fritz!Box

You can capture network packets on a Fritz!Box for any interface by:
dtrace parameters in the edit boxExample URL: 192.168.178.1/html/capture.html
Note it’s ISDN [WayBack] Dtrace – Fritz!Box, not nx kernel [WayBack] DTrace – Wikipedia
I’ve seen this on these devices:
Note there are tons of tools allowing to capture from various scripting languages:

A while back, Thomas Mueller assumed that Satellite internet could be an alternative for rural areas in Germany: [WayBack] > Auch der Internet-Anschluss über Satellit funktioniere allenfalls quälend langsam <Das kommt mir aber ziemlich seltsam vor… – Thomas Mueller (dummzeuch) – Google+ as a response to [Archive.is] Telekom-Posse: Wirt soll eine Million Euro für schnelles Internet zahlen – WELT.
So I summed up what throttling to 600 (optimistic) or 1000 millisecond (realistic) latency on a 10 megabit connection means: awfully slow for interactive use.
The problem with satellite based internet is latency times: 500 milliseconds is the physical minimum for a geostationary connection. It can easily double with overbooked connections (default with consumer DSL/Cable/Fiber).
The latency combined with the very chatty nature of most applications, is the real killer for your experience.
Compare that to my speeds 2 years ago: https://wiert.me/2015/10/05/fiber-to-fiber-speed-beats-cable-to-fiber-speed-by-a-factor-2-all-three-internet-connections-are-in-the-same-house/
I just did a comparison with the fiber connection at my brother (who lives some 20 miles away) and work too and re-checked the fiber connections in the article (they stayed the same).
- fiber 1 = home
- fiber 2 = home
- fiber 3 = brother
- fiber 4 = work
Traceroute results:
- fiber 1 to fiber 2: 5 milliseconds
- fiber 3 to fiber 2: 8 milliseconds
- fiber 4 to fiber 2: 4 milliseconds
- cable to fiber 2: 10 millseconds
- ADSL to fiber 2: 15 millseconds
With these, you can have > 50 connections per second.
Satellite gives you 2 connections per second if you are lucky.
The blog page takes ~160 web requests.
- DOM content load ~ 1.0 seconds
- Full load finished ~2.2 seconds
- Render finished ~5.0 seconds
I throttled it down to Satellite speed:
- 10 megabit downstream
- 2 megabit upstream
- 600 millisecond latency
Now this is the load:
- DOM content load ~ 2.9 seconds
- Full load finished ~9.9 seconds
- Render finished ~10.0 seconds
Increasing the latency to 1000 milliseconds brings this:
- DOM content load ~ 4.2 seconds
- Full load finished ~11.8 seconds
- Render finished ~14.9 seconds
Fully loading gmail.com or booking .com with 1000 millisecond latency takes over 30 seconds.

When you want to download actual known amounts of bytes, then use the [Archive.is] XS4ALL Software download site which has plenty of files in both sizes that are powers of 1024 and powers of 1000, so you can use the units that fits you best:
I usually run commands like these:
traceroute download.xs4all.nl & wget -O /dev/null http://download.xs4all.nl/test/2GiB.bin
traceroute download.xs4all.nl & wget -O /dev/null http://download.xs4all.nl/test/10GiB.bin
The first is for speeds up to ~100 megabit/second, the latter for speeds up to ~1 gigabits/second; wget examples based on [WayBack] linux – How do I request a file but not save it with Wget? – Stack Overflow.
From the xs4all shell servers, you have about 1 gigabit speed. At home it is about 80 gigabit.
Since the download is over a longer period of time, you get a better estimate of average speeds than regular speedtest varieties do.

Not sure why Privacy Badger blocked both fsdn.com and a.fsdn.com (if someone knows how to find that out: please let me know), but these are CDN domains are used by Slashdot and sf.net, so I have put a.fsdn.com from red to yellow (no cookies).
I have not unblocked s.fsdn.com, which redirects to sourceforge.net over TLS.

A while back, I needed to show the Teamup Calendar for my marching band at a specific date.
Luckily I found [Wayback/Archive] Calendar Link ParametersTeamup Calendar allowing me to assemble such link:

Which shows at the end of the month, we are going to perform on Tattoo on Stage in Luzern (Lucerne), Switzerland in the famous KKL concert hall:

We’ve been there before and it’s great fun! The [Wayback/Archive] New Zealand Army Band even did a haka challenge with us.

I need to dig a bit deeper into these links to see how easy it is to record calls made on a Fritz!Box then playing back the captured calls.
Note that in various countries you have to indicate to the calling parties that their calls can be recorded.
