I don't have any FritzBox.
I have a little BananaPI with Debian 9 configured as Router and
connected to a DSL-Modem.
On the BananaPI I installed Asterisk, to have it directly connected to
the Internet.

I can try it...
Now it's too late for the test. I'll try tomorrow.

Bwahahahahahah!!!! The technician of DT, at least the people answering
the Hotline, don't have any idea _WHAT_ is VoIP and so on...
They only can say "you have to power off your FritzBox, wait 30 seconds
and power it on again".
If I say, that I don't have any FritzBox they give a Brain core dumped...

Really a pity... :(

As I said, I have a BananaPI with a Debian 9, minimal installed from me
with some scripts to manage the DSL.
Asterisk was installed from Debian Repositories.
