[Serusers] decoding g729 encoded rtp streams

[İlker Aktuna (Koç.net)]

Hi,

Thanks for the information.
Actually, I downloaded it but couldn't find how to export rtp payload.
Does rtpdump read capture files recorded with Ethereal/tcpdump ?
(in which format should I save the file?)

Btw, there is a Windows sniffer named "Cain & Abel" this one decodes g729.

Thanks,
ilker

You can download the decoder from: http://www.voiceage.com/openinit_g729.php

Then capture the RTP Stream with Ethereal and export the Payload (using rtpdump from http://www.cs.columbia.edu/IRT/software/rtptools/).

You can then decode it with the above software.
