Re: [Serusers] decoding g729 encoded rtp streams

Hi, Thanks for the detailed explanation. It's really useful. I'm trying to automate this whole process. All tools except Ethereal (tcpdump, rtpdump, voiceage decoder) are command line tools that can be used in a batch/shell script. How can I export rtp stream without using Ethereal, or from command line ? is there a way ?

Open Capture 2. Click on Analyze->Statistics->RTP Streams->Show All 3. Select the stream you want to export 4. Click 'Save As' 5. Then feed that file into rtpdump like the below example 'trace.rtp'. Here is the command line: rtpdump -F payload -f trace.rtp -o file.out file.out will contain just the payload which can then be decoded. _____________________________________________________________________________________________________________________________________________ Bu e-posta mesaji kisiye ozel olup, gizli bilgiler iceriyor olabilir.
