SIP Workbench is a graphical SIP, RTP, STUN, and TURN protocol analyzer and viewer designed to help illustrate and correlate VoIP and IM network interactions. SIP Workbench is a versatile tool designed for protocol developers, system integrators, and end-users to use to visualize, diagnose, and debug complex multi-protocol interactions.
SIP Workbench reads Ethereal/Wiresharp libpcap files and can perform live captures itself. Additionally, it can export SIP, RTP, and STUN information in text-based ladder diagram.
Users can quickly review packet interactions, filter on a particular flow, and identify retransmissions, timing inconsistencies, failed requests, dropped responses, and routing issues. These features allow for quicker diagnosis and resolution of problems.
While a troubleshooting a problem, users can export ASCII representations of an interaction, annotate it, and share it with a vendor, system administrator, or developer. Users can export an entire packet capture or a particular flow or the contents of a single message.
SIP Workbench includes visual indicators representing negative responses, missing responses, media start events, and timing characteristics. Different messages and message types are color coded to highlight and separate potential problems from expected interactions.
Those unfamiliar with SIP, STUN, TURN and RTP benefit from SIP Workbench's intuitive graphical interface that allows users to visualize interactions and compare message flows. Sample captures are also included.
