tool: D114: analyze

tool: D186: decrypt

tool: D250: info

tool: D274: 


tool: D57: To decrypt an SRTP audio stream you need the key material that was used to encrypt it. 

tool: D163: Get it from a SIP trace or from a log file. 

tool: D100: The key material is a 40 byte character string, for example CXL0YTLiYrsKYDAsxAJKTWqQaBg1PQhUH9iFwPAp.

tool: D121: You also need the SSRC value of the SRTP audio stream. One way of doing this is by running %s analyze.






tool: D30: For a G.711 RTP stream (PCMU or PCMA) %s creates a .wav file that can be played directly.




tool: D195: For a G.722 RTP stream %s creates a RAW file with .g722 extension. Use ffmpeg to convert:


tool: D91: ffmpeg -i file.g722 file.wav



tool: D38: For a SILK 8KHz RTP stream %s creates a SILK SDK file with .bin extension. To convert use:


tool: D213: decoder.exe file-SILK8000.bin help.pcm -Fs_API 8000

tool: D14: ffmpeg.exe -f s16le -ar 8000 -i help.pcm out.wav



tool: D168: For a SILK 16KHz RTP stream %s creates a SILK SDK file with .bin extension. To convert use:


tool: D143: decoder.exe file-SILK16000.bin help.pcm -Fs_API 16000

tool: D253: ffmpeg.exe -f s16le -ar 16000 -i help.pcm out.wav




tool: D109: Codecs other than G.711, G.722, SILK/8000 and SILK/16000 are not supported.

tool: D251: Provide a pcap file as second argument.

tool: D34: %s will try to find RTP media streams in the pcap file and display some info including the SSRC value.


tool: D236: Example:
%s analyze file.pcap


tool: D83: Provide the SSRC value of the SRTP stream to decrypt as second argument in Hex notation with leading 0x.

tool: D62: Provide the key material to be used for decryption as third argument as 40 character base64 value.

tool: D286: Provide the pcap file that contains the SRTP stream as fourth argument.


tool: D188: %s will create an output file that contains the decrypted audio data.


tool: D184: For further information run %s help info.



tool: D283: Example:
%s decrypt 0x72c4827b CXL0YTLiYrsKYDAsxAJKTWqQaBg1PQhUH9iFwPAp file.pcap
