DSL ping spikes

[Dmitrek]

We have a Vodafone Business DSL in the office with a Fritzbox 7590. It is almost impossible to use any online meetings - each minute ping spikes for one second to 1000ms+, breaking and freezing all the calls. It was said on the forum here and other forums that Fritzbox might be the issue (with some "packet acceleration" setting), but it seems I can't fix it.

Any help? Ideas?
