asterisk users - Feb 2006 - Re: Opinions needed on call quality vs

You cant go by pings.  ICMP traffic is given lowest priority on internet
routers, where voip rtp or iax might be given much higher priority.  Plus I
have 2 providers, the provider with the 90ms ICMP ping time is way better
than the provider with the 15ms ping time.  It depends on so many factors,
including their equipment.  I have a continuing problem with the voice
dropping out for 1 second or less during a call and both providers have this
problem but I haven't been able to figure out where the problem is coming
from, inside my network they are on their own lan and the sound is great but
using IAX or SIP to connect to teliax or voicepulse has these damn audio
dropouts, and I even tried jitter buffer, 2 asterisk boxes, 2 different
internet connections one DSL and one cable, and various codecs and a mix and
match of all this.  Anyways your best bet is to get a pay as you go account
and test....

Thanks Mike.  I am surprised there isn't a basic "call quality
tool"
available that tests RTP traffic between two points. But I get your point
about the ICMP packets.  I just figured it was a good way to test traffic
between two points, at least the portion what doesn't belong to that
provider (I am assuming the people in the middle don't prioritize RTP
traffic, which might be a wrong assumption)
