Summary: Pcap Play packets have a UDP source port of Zero (0)
Initial Comment:
I am trying to use the PcapPlay feature to perform IVR tests against a Convedia
CMS-6000 media server, but the media server doesn’t hear/detect the DTMF tones.
When I use tcpdump or Ethereal to look at the injected RTP packets they all
have a UDP Src Port of zero (0), while the rtp echo’d packets all have valid
source and destination ports.
Running a “tcpdump -vv src port 0” at the same time as the following sipp
command line will capture the 50 packets sent.
