You should rule out your net connection first.

Run a tracert to sipgate's server just to check if your traffic is
taking an overly funky route. Post your results back here.

Also, visit here - http://testmyvoip.com/

Check preserve speech quality
Pick London in the drop down list (no German test point im afraid)

Let me know what results come back. It should give you some idea of any
packet loss you are having on your line.
