[App_rpt-users] Distorted audio - no explanation

[(KP4TR)Ramon Gonzalez]

I am almost 98% sure my problem is related to the IAX jitterbuffer feature

The reason I say this is because it happened suddenly, and it was 
occurring on 2 separate servers within the same network. Also the 
Remoterig device that allows me to remote control/use a radio uses SIP 
and has similar features as Allstar/Asterisk that I adjust based on 
bandwidth.

Now I need to understand why this has changed and how to solve it. My 
Allstar node(s) are currently unusable because I sound with lots of 
packet loss. But I can hear everyone well, and the echolink connection 
via Allstar sounds fine.
