I'm involved in a small VoIP operation and every now and then I find myself taking captures of VoIP (SIP / H323) communication to analyze and solve problems. However time to time I bump into voice quality issues and I would like to capture and listed to the RTP streams to listen to whats wrong.
If the call is on G711 codec, there is no problem as Wireshark allows to Decode and Play the RTP steam or save it to play later. However, most of my calls are on G723 or G729, or sometimes even on iLBC.
I would like to find a way to enable Wireshark to decode and play G723 / G729 codecs. I understand these are licensed codecs and there might not be a straightforward way, however even if there is a plugin / decoder which I can purchase and pay the codec royalty fee, I wouldn't mind that either.
Please let me know if there is any product / solution out there which can do what I'm looking for.
