libfindrtp

libfindrtp is a specialized library package designed for use with various Voice over IP (VoIP) tools within the Kali Linux ecosystem. This package contains the core library that enables multiple VoIP analysis and manipulation tools to function properly.

The library is particularly useful in network security testing scenarios involving VoIP protocols, where tools need to detect, capture, or analyze RTP streams and related VoIP traffic. By providing a standardized library interface, libfindrtp ensures consistency across different VoIP tools that depend on its capabilities.

As a dependency package, libfindrtp supports the broader Kali Linux toolkit for network reconnaissance, traffic analysis, and protocol testing in VoIP environments. It is lightweight with an installed size of just 35 KB, making it efficient for deployment in security testing environments.

libfindrtp operates as a shared library (libfindrtp.so) that VoIP tools link against to access RTP stream detection and manipulation functions. It leverages underlying networking libraries like libpcap0.8t64 for packet capture and libc6 for core system interfaces. The library implements algorithms to identify RTP packets within network captures based on RTP protocol characteristics (UDP ports, payload types, sequence numbers), enabling VoIP tools to locate, extract, and process multimedia streams from captured traffic.
