RTP stream is empty or codec is unsupported

I'm trying to analyze a VoIP call (RingCentral) but cannot get any audio playback. The stream can be found under Telephony > VoIP Calls as well as Telephony > RTP > RTP Streams but attempting to "Play Stream" just results in "RTP stream is empty or codec is unsupported". The codec is detected as Opus. I'm unsure how to troubleshoot this further.

Only a few codecs are supported for playback due to licensing. Opus is not one of the supported ones.

So is there any way to play these files, or convert them to something that is supported?

Export the RTP payload as raw file and feed that into a decoder. That's the procedure in short. Additional problems arise when the packet boundaries are also relevant for the decoder as well, that information cannot be contained in a raw file. That would require a container format, something that is not supported.
