Wireshark-dev: Re: [Wireshark-dev] Query regarding RTP dissector in Wireshark

Specifications (for RTP multiplexing and header compression) are:
- 3GPP TS 29.414
- 3GPP TR 43.903

Interface is GSM A-interface over IP (BSC <-> MSC), BSSMAP controlled.

Munish

No, RTP MUxing is not yet supported, neither does header compression AFAIK.

In order to implement suppiort for that we need two things:
pointers to the specs and capture files to test it.

MUXing implementation cuold be prety complex as it might step way outside our framework for maintaining conversation info.

I guess you have Iu-Over-IP and/or GSM-over-Iu (is that a RANAP controlled BSC?) that no-one of the Wireshark developers have ever seen.
