The Milkfish is an Embedded Communications Software Project. Main objective is to provide a basic NAT traversal solution for cheap hardware enabling a practical setup of multiple SIP phones in a LAN sharing a WAN connection with one public IP address.
SIPatHome was based on the SIP Express Router (SER) which is a well-tested, configurable, free and RFC3261-compliant SIP proxy. The project was providing VoIP server software for the embedded Linux distribution OpenWRT on affordable Linksys WRT hardware.
