PCAP to Audio File Converter
Budget: $30 – $250 USD
We will provide a .pcap file captured with tcpdump. The file captures VOIP calls made on our network.
You will write a command-line utility program that reads the pcap file and outputs the RDP audio streams into .au files. The audio is in 8000hz PCU format generated by SIP telephone calls.
For each SIP telephone call you will provide THREE audio files. One file will contain the RDP audio for each separate side of the conversation. The third audio file will contain BOTH sides of the conversation.
In addition, for each SIP conversation, you will provide a data file containing JSON text, showing the TIME and DATE of the call for the PACIFIC timezone; also TO and FROM fields showing the names of the caller and person called, if these are available in the packets.
The program will be written in PYTHON, and you will provide the python code, and also assign ownership of the code to us. The code should be runnable as a LINUX service under Ubuntu.
A typical pcap file is attached.
