Hi All,
I'm contacting you because I've a strange issue with PCAP and RTP packets.
I'm sending a PCAP file to be reproduced when I run sipp.
Unfortunately, sometime I can heard noise and tones but sometimes not.
I don't understand very well this problem and I don't know if my script is
wrong or I am missing something.
Because it works sometimes as I said.
I copied my script below and the command line I execute to run it.
If anybody can help me I will appreciate that.
