I am trying to trouble shoot one of my ISP's network and compare to my
other ISPs offering. Although network 1 is reasonably fast and has low
enough latency, voice quality is not good and the reason for this is
not readily apparent using standard network tools.
What tools can be used to assess the quality of the network in terms
of it's suitability for voice? I am using ping, mtr, smokeping for
general network reliability and using visualroute to give me info, but
I need some voice specific quality metrics. Any ideas?
IPERF is definitely our tool of choice. We can measure UDP packet loss
and jitter. We setup the packet sizes identical to the respective codec
we want to compare to and for all intents and purposes the stream will
be just like an RTP stream.
