Challenge description:

Extract a voice.
The flag format is SECCON{[A-Z0-9]}.

A straightforward challenge. It is clearly mentioned that  we need to extract the voice message. Also, you can see the RTP streams when you open the PCAP file in Wireshark.


Get the flag by playing the voice message after extracting the VoIP call from the menu (Telephony -> VoIP calls)

The Flag was : SECCON{{9001IVR}
