Google around again, you will find something.
From wireshark gui interface, you must save the rtp streams and then convert. You will probanly find a script to do exactly that.
You muat pay attention that your pcap file contains the rtp streams too (not only sip signaling).
Anyway, this is a question you would better asks to the wireshark mailing list, is not a quewtion related to FreeSWITCH.

Hello ,
Please i need to convert pcap file to wav file with comman linux in freeswitch to play back this file .wav
i found this : 1 step : write a script to convert pcap to wav wich is : ssrc=$(tshark -n -r /home/amani/projet/PFE/test.pcap -R rtp -T fields -e rtp.ssrc -Eseparator=, | sort -u | awk 'FNR ==1 {print}')
echo $ssrc
sudo tshark -n -r /home/amani/projet/PFE/test.pcap -R rtp -R "rtp.ssrc == $ssrc" -T fields -e rtp.payload | tee payloads
for payload in `cat payloads`; do IFS=:; for byte in $payload; do printf "\\x$byte" >> /home/amani/projet/PFE/test.raw; done; done
echo ‘sox has converted pcap to wav file’
sox -t raw -r 8000 -v 4 -c 1 -e mu-law /home/amani/projet/PFE/test.raw /home/amani/projet/PFE/test.wav
==> but when i run this script the error is : tshark: -R without -2 is deprecated. For single-pass filtering use -Y. ‘sox has converted pcap to wav file’ sox FAIL formats: can't open input file `/home/amani/projet/PFE/test.raw': No such file or directory
Rq: paylods file is empty :(
please can you help me ???
thanks with regards amani
