Iaxclient Project. A project to create a cross-platform IAX-protocol IP telephony client.

IAX is the native protocol used by The Asterisk PBX Although asterisk supports other IP protocols (including SIP, and with patches, H.323), IAX2's simple, lightweight nature gives it several advantages, particularly in that it can operate easily through NAT and packet firewalls, and it is easily extensible and simple to understand.
