Asus RT-N12 with Tomato ND USB mod with kernel 2.6, beta11. With my Linksys PAP2, I have an issue in which there is no incoming SIP audio when I'm using Tomato. But it works fine when I use DD-WRT or stock Asus firmware. What settings difference could there be between Tomato and DD-WRT to cause this? The only settings I've altered are the wireless settings (e.g. to N-only with WPA2-AES).
