Internet link and troubled VoIP

Hi

A client has a hosted Asterisk server in a data center that connects to a remote Centrex

Conversations are frequently (and heavily) disrupted with static and parasite noises

We were told by the Asterisk maintainer that there were a lot of lost packets between the datacenter and the Centrex

No one seems to admit or recognize the clients issues.

The Centrex support sent us the following MTR output :

Open in new window

I'm not sure how to interpret this result; I would assume that one reads it like a traceroute output
So the two "No responses" before reaching the host 217.242.120.250 don't seem normal to me

What are your thoughts ?
