Jaap,

What I mean is for example; when you
capture T.38 frames which are rtp.version=0, you can see on the ethereal
capture display for packet details the udptl portion and this breaks down
to show error recovery(prior pkt data).  RFC 2198 is for RTP frames
for encoding redundant audio data.  So what I would like to see is
that ethereal display can break these down within the display as well to
show the primary data and the redundant data separate.  I do not have
an example capture, but this is specifically concerning V.152.  Can
ethereal do this?

Thanks,

Debra

Subject	Re: [Ethereal-users] Ethereal support of RFC 2198 RTP Payload for        Redundant Audio Data:

Hi,

Ethereal is capable of dumping the RTP stream in a rtpplay file. It is
capable of decoding simple u-law and A-law audio streams into an audio
file. It is also capable to analyzing the RTP packet stream (for said
audio streams specifically).

I'm not sure what you mean by "displaying FEC per RFC 2198?".

Thanx,
Jaap
