I am pretty sure that Wireshark just uses missing RTP sequence numbers (rtp.seq) to calculate loss. I just took a G729 RTP stream and manually deleted a few frames, reloaded, and the Telephony:RTP:Show All Streams statistics definitely showed the appropriate loss.

Hi,all: I'm using wireshark to capture a VOIP-alike telephony call. The packets are RTP, which carry audio payload encoded with G729 codec, I use dummynet to impose packet loss. Previously, when the codec is G711, wireshark can show the exact packet loss, Now the codec is G729, the wireshark always shows 0 packet loss when I set packet loss to 2%, is it because that the wireshark is not able to analyse G729 audio stream and thus just show 0% loss?
