hi,
I am working on a project to perform the voip call quality.
i want to get some statistics about the call quality with asterisk.
I used the following command: iax2 show netstats
and the result changes depending on the configuration of iax.conf.
When i enable jitterbuffer=yes and forcejitterbuffer=yes, i get the following
result:
voip*CLI> iax2 show netstats
-------- LOCAL --------------------- --------
REMOTE --------------------
Channel RTT Jit Del Lost % Drop OOO Kpkts Jit Del Lost % Drop OOO Kpkts
IAX2/i55333-6207 1500 2 42 0 0 0 0 0 0 0 0 0 0 0 0
1 active IAX channel
voip*CLI> iax2 show netstats
-------- LOCAL --------------------- --------
REMOTE --------------------

IAX2/i55333-6207 22 2 43 1 0 0 0 1 0 40 0 0 0 0 0

and when i disable it i get:
voip*CLI> iax2 show netstats
-------- LOCAL --------------------- --------
REMOTE --------------------
Channel RTT Jit Del Lost % Drop OOO Kpkts Jit Del Lost % Drop OOO Kpkts
IAX2/i55333-11724 1500 -1 0 -1 -1 0 -1 0 0 0 0 0 0 0 0

Should i enable it or not?
Is there any threshold for the field "lost" and "%" for
which we can say that
the call quality is bad?
Thank you
