Ever wished for your own VoIP PBX at home?
SIPatH is an Open Source Project aiming on making your Broadcom based hardware router a fully qualified VoIP Router.
This is tried to be accomplished by an approach consisting of three steps:
1. Flashing the Router with OpenWrt Linux
2. Configuring OpenWrt and installing the SIPatH packages
3. Setting the SIPatH Router IP as the Outbound Proxy in your IP Phones Config Interface

Additionally SIPatHome is powered by SER (Sip Express Router) the best and most flexible Open Source VoIP Server, and supports Asterisk for the PSTNGW stuff.
