I've modified the test slightly to simulate a typical high-quality VOIP connection - 100pps, 80B payload size. On your connection:
Packets: sent=1000, rcvd=1000, error=0, lost=0 (0.0% loss) in 10.029377 sec
RTTs of replies in ms: min/avg/max/dev: 20.327 / 32.502 / 53.147 / 5.985
Bandwidth in kb/sec: sent=10.768, rcvd=10.768
Out of sequence packets: 21

Note the Std. Dev figures don't tell the whole story, as packet to packet jitter on VM in my area is quite low, with occasional "gaps" of 20ms+ e.g.:
Yet on yours it's constantly variable but most jumps are <10ms:
And despite st.dev. being less than 2x as high in your area, out of sequence packets are over 10x higher, the latter being, as mentioned, quite disruptive to VOIP communications
