AMR codec payload missing



I am trying to capture an AMR codec generated using Navtel. When I decode it to RTP, the trace shows "RTP EVENT" instead of "RTP" and the payload is missing in all of those packets.

I have used the same setup for various other codecs like PCMU, PCMA, AMR-WB, etc which are captured fine. What could be the cause and a possible solution?

P.S.: I have just started off as an intern, so I am quite new to Wireshark!

One Answer:


If you want RTP event out of the way you should look at the preference settings for the RTP Event protocol. There's probably a payload type set that the Navtel uses.
