As the subject line says: Is PING a good indicator of network
latency?
If
not, how can I measure latency?
Using Asterisk is a good way. If you define a phone in sip.conf and
turn
on "qualify=", we will measure the latency for the network between the
phone and Asterisk.

Qualify= runs one SIP OPTIONS per 60 second interval, right? And then
only the latest response is shown.
Not really enough sample points to determine if the network will support
RTP and no provision for jitter measurements and packet loss.
I really like the statistics on the cheap Linksys ATAs! - latency,
jitter, packet loss during an actual call.
For a newbie, it's a start, but you are absolutely right. The work we
are doing with RTCP support will help in this, measuring quality per
call. Those of you that wants to test, please go to the bug tracker for
more information! We need input on what to do with the data, how to
publish it.
