"The Codenomicon tools are amazing. Using them is like being attacked by the most relentless adversary who uses every possible method to find flaws in your code

We fixed subtle crash bugs in Samba that had been in the code for over ten years. We would never have found those bugs without the Codenomicon tools.

If you're serious about implementing protocols correctly, you need the Codenomicon tools."

   Co Creator of Samba

Codenomicon SigComp Test Tool Data Sheet

  • Test tool: Codenomicon SigComp Test Tool
  • Direction: Server and Client
  • Tagline: Ensuring Robust Signal Compression

With Codenomicon SigComp Test Tool, you can proactively eliminate robustness flaws from your critical next-generation VoIP devices and infrastructure. This saves development and maintenance costs, produces more stable systems, and enhances your product and corporate image. Codenomicon SigComp Test Tool is essential for anyone who develops SigComp implementations or depends on the robust functioning of next-generation VoIP services.

SigComp (Signaling Compression) is a solution for compressing messages generated by application protocols such as the Session Initiation Protocol (SIP) (RFC3261) and the Real Time Streaming Protocol (RTSP) (RFC 2326). The decompression functionality is provided by a decompression virtual machine (UDVM) which provides an instruction set optimised for decompression algorithms. The bytecode for decompressing the compressed message is transmitted with the message. Codenomicon SigComp Test Tool can be used to test any SigComp implementations.
