After looking around the web without success for a secure VoIP application, I decided to build one: OmilyX. For the sake of brevity, the key features of OmilyX are: - Perfect forward secrecy (Diffie-Hellman key exchange for every call) - Anonymity (contact details, e.g. email address etc., not required) - NAT traversal (UDP hole punching) - Low bandwidth (6kb/s total including all overheads) - Great sound quality (Speex) - Works with PocketPC and Windows To try the beta release and for more details visit http://www.omilyx.com Prakash
