Hi,
In RTP streams "Wrong timestamp" means that the timestamp received in the packet isn't what was expected. Of course expectations need to be based on something, in this case the RTP profile, codec, packet size, etc. Wireshark is good in detecting these for straight forward PCM A/u-law streams, but other profiles are not supported. This shows when there's Silence Suppression, RTP events or other codecs involved. With video streams again you'll run into the same issues. This story applies to "Out of seq" as well. 

Thanks,
Jaap

Hello,

Can anyone tell me what does "Wrong timestamp" and "Out of seq" mean. Its related to Voip calls and media stream. Also it would be useful to know what could be the reason having high value regarding these two.

Thanks in advance!
