If you are like me, you use Wireshark every day. For me that means troubleshooting many different network situations, including Voice traffic - VoIP. Wireshark announced some significant changes coming to the Voice capabilities set within Wireshark, and I hope you are like me - extremely excited to see these.
If you want to learn how to analyze/troubleshoot voice with Wireshark, check out my video:
According to the Wireshark Web Site:
First: significant RTP Player redesign and improvements (see Wireshark User Documentation, Playing VoIP Calls and RTP Player Window)
- RTP Player can play many streams in row
- UI is more responsive
- RTP Player maintains playlist, other tools can add/remove streams to it
- Every stream can be muted or routed to L/R channel for replay
- Save audio is moved from RTP Analysis to RTP Player. RTP Player saves what was played. RTP Player can save in multichannel .au or .wav.
- RTP Player added to menu Telephony>RTP>RTP Player
Second: VoIP dialogs (VoIP Calls, RTP Streams, RTP Analysis, RTP Player, SIP Flows) are non-modal, can stay opened on background. This also means the same tools are provided across all dialogs (Prepare Filter, Analyze, RTP Player …)
Lastly, follow stream is now able to follow SIP calls based on their Call-ID value.
These are all very positive changes and I thank the development team at Wireshark for sprucing up the voice support! Also - be sure to grab the voice profiles as mentioned in the video. You can find those right here: https://www.cellstream.com/resources/wireshark-profiles-repository
