"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 H.248 MGC Test Tool Data Sheet

  • Test tool: Codenomicon H.248 MGC Test Tool
  • Direction: Media Gateway Controller

The Media Gateway Control Protocol (MEGACO, H.248) is a protocol user in physically decomposed Multimedia Gateways. Since the proper functioning of the H.248 protocol is vital to multimedia networks, the dependability of H.248 implementations must be verified. This test application can be used to test H.248 MGC implementations for security flaws and robustness problems.
