Hi, Is this dissector code for "RTP multiplexed streams" submitted to Wireshark ? What is the bug number ?

At present it only handles the uncompressed RTP header case, but should provide a starting point for further development. BTW we have called the protocol nb_rtpmux, as the 29.414 spec is originally for the Nb interface.

Presently we 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.
