What RFC's are you referring to in the text below ? Thanx, Jaap On Tue, 3 Nov 2009 17:19:51 +0530, shruti singh <shruti.is.singh () gmail com> wrote:

can
decode only Non -Multiplexed RTP streams in wireshark. A multiplexed voice packet is composed by concatenating RTP
encapsulated
voice packets and IP and UDP headers. Below is the Multiplex Packet format IP UDP Multiplex Header Compressed RTP Header RTP Payload Multiplex Header Compressed RTP Header RTP Payload This Multiplex header is repeated in beginning of each RTP packet. So
I was thinking of way to extract this multiplex header & use it to decode
each
RTP packet following this Multiplex header. I supose we need to make a dissector packet-rtpmultiplex.c regestring
to
a UDP port as a starting point. Dissect the multiplex header, decompress the rtp header and have the
RTP
dissector dissecting the resulting "RTP packet" - decompressed header+data. Could you help me in dissecting the multiplex header and make this
work.
Also I need to know the steps to write our own filters in wireshark It would be great help. Kindly reply as soon as possible Regards Shruti
