RTP player voice playback problem



I would like to ask a question about RTP streams playback. When I finished rtp packet capture and perform voice packet playback, I can not hear any sound. I found Sample Rate (Hz) field shows zero, instead of 8000 (as shown below). How do I resolve this issue ?Is there a correlation between this issue and the Sample Rate(Hz)?

Thank you in advance.

One Answer:


Wireshark does not embed a G.729 decoder because it's not patent free.

You can follow the procedure described on this wiki page to manually decode the stream.
