ilty is an interception phone system for VoIP network, started in 2005 as a proof of concept on how easy it was to listen to conversations. ilty's main features are :

• Listing, in Live, of a conversation
• Recording of multiple call in background
• A "history" mode, to see what happened
• More evil features in an unreleased/private version in switched environnement (theses features are easy to code with scapy if you want them)

ilty is a Python application, not really suitable for an micro-embedded plateform, and is only available on Linux. The port to another platform shouldn't be that hard. Some experimental features are still under development like a module of automatic network discovery (passively or not), rogue DHCP, etc.
