Via VoIP...

Deutsche Telekom uses since years just VoIP. No ISDN, PSTN, and so on... :(
I'm connecting to the VoIP-Server of Deutsche Telekom via DSL (50Mbps
down, 10Mbps up).
The other party use VoIP, too, since they are in Germany (and Italy) and
here there are just VoIP... Sigh!

Now I disabled the jitter (jbenable = no), and I called my father in
law. He sayd me, the quality is really better, but I hear sometimes
little noises...

Any other suggestion?
