Hi Sammy,
Sure I will paste the stats here but will you please tell me some important
steps to be performed on software side. Here I am talking about the OS, kernel
upgrade & advanced system administration level stuff that can reduce the packet
loss immediately. Through the final conclusions I have become to know that its
not the OpenSIPS problem but it regards with physical, software & network
upgrades.
Regards,
Faisal Rehman

Subject: Re: [OpenSIPS-Users] Packet Loss and its Solution
Hi Faisal,
Can you copy/paste the stats of "ifconfig ethN" on which traffic is
terminating. I just wanted to see the error and dropped packets on physical
interface.
Hardware and physical connectivity plays major role in packet losses.OnAsterisk
server Jitter options might help you but this is media-proxy, I assume from the
interface you are viewing, the packets are shown as lost. So could it be heavy
media traffic flowing through the interface and media proxy is unable to use
much CPU processing power to process all the RTPs ?
Before troubleshooting the software application I suggest start digging the
networking interfaces and tweak the ethN and related properties of kernel to
maximize the throughput.
This would be just how I'd go with this kind of problem.
Regards.
Sammy
