Description:hi,

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

and when i disable it i get:

voip*CLI> iax2 show netstats
                               -------- LOCAL ---------------------  -------- REMOTE --------------------

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
