Here you go!1. Enter RTP in the display filter in Wireshark when the capture is open.2. Now select an RTP packet in any stream and click on the menu option Telephony.3. Go to RTP Stream Analysis and click on Save Payload button.4. Change the format to.au and choose a name (lets say test.au) and location for your file.5. Play it using your favorite audio player.OR5.

Run the following command to convert the.au file to.wav if you like.wav files better: sox test.au -V -t wav -b 16 -c 2 test.wavHope that helps!
I have a UDP packet capture which was streamed from Port1 on IP1 to Port2 on IP2 on network N1. I need to replay these packets on another network N2 from Port3 on IP3 to Port4 on IP4.I need to know what software to use in order to do this and how I would go about replaying these packets so that I can detect/capture them again in N2.So far, I've tried strictly replaying these packets using a program called Colasoft Packet Player, with little luck.I'd appreciate any help on this.Thank you in advance. Tcpreplay would also appear be able to do what you want, maybe in a single step using the tcprelat-edit program, but I haven't personally run this software.From the tcpreplay-edit:tcpreplay has evolved quite a bit over the years. In the 1.x days, it merely read packets and sent then back on the wire. In 2.x, tcpreplay was enhanced significantly to add various rewriting functionality but at the cost of complexity, performance and bloat. Now in 3.x, tcpreplay has returned to its roots to be a lean packet sending machine and the editing functions have moved to tcprewrite and a powerful tcpreplay-edit which combines the two.Since tcpreplay-edit includes all the functionality of both tcpreplay and tcprewrite please see those wiki pages for how to use tcpreplay-edit.

BitTwist should be able to do what you want.With Bit-Twist, you can now regenerate your captured traffic onto a live network! Packets are generated from tcpdump trace file (.pcap file). Bit-Twist also comes with a comprehensive trace file editor to allow you to change the contents of a trace file.The 'trace file editor' part is what you are most interested in here.I think you need to transform in two passes: one to change the IP addresses, another to change the UDP port numbers. I believe you can do this in either order.
