Decrypt SRTP

0

Hi, I have a SIP Call with SRTP (G711 PCMU). The SDP is in ICE. Is it possible to listen the voice stream via Wireshark? If yes, what is to do? If no, what can i do about to listen the SRTP streams?

You can download the trace here: https://dev.c4b.de/downloads/hau/Whireshark/Call_ICE.zip

Thanks a lot!

No, because there's no SRTP decryption support build into Wireshark at this moment. Saving raw data from RTP stream analysis would be the first step at getting at the data, then you'll have to feed it through a decryptor.
