[OpenSIPS-Users] Packet Loss and its Solution

[Max Mühlbronner]

Hi,


20% might be true for general network usage, but not for Voice traffic. 
Also it depends on the codecs used, 10% packetloss at VoIP means quality 
will be degraded (codec could only compensate up to 5%).

g711 at 10% packetloss:

pre-sip / h323, but also example files at different packetloss rates, 
tune in to the 20%  g711 wav file...  :)
