After a system reboot, I get some advances. (systemd includes too much
sorcery for me)

Now I can execute jack_evmon in another terminal and see activity of the
jackd server:
$ jack_evmon

Client SIP/6007-00000000 registered

Port 5 registered
Port 6 registered

Unfortunately there are still (other) errors in the asterisk console:
    -- Executing [6000 at default:5] JACK("SIP/6007-00000000", "") in new stack

Indeed, I have no audio in the phone.
There are probably other issues elsewhere in my system...
The adventure goes on!
