I want to have a look at the make up of IP/UDP/RTP packets in “real conversation”, i.e. what exactly does the IP packet look like, field values etc.
So if i set up a Netmeeting or MSN IM audio call and get a packet sniffer, i should see this make up?
Does anyone know any good free packet sniffers that support RTP? Or anyone know anything about packet sniffers?
I’ve downloaded a few such as “Ethereal” and a shareware version of “Commview”, which claim to support RTP, but when i run Netmeet or MSN IM, they only record the ethernet/ip/udp headers, with the udp header carrying “protocol data” instead of showing me the RTP header.
Any help on this is appreciated,
