Linksys 3102 - PSTN wont pass to asterisk

[batrams]

I have a Linksys 3102 which I want to connect to my asterisk 1.2.17 server. I can get the Line1 to work - I can dial an extension and get an analog phone connected to the 3102 to ring.

I can't however get incoming calls to the PSTN to get passed thru to asterisk. The calls do appear on the 3102's admin gui, but I see no errors or other activity on the asterisk command line.

I've upgraded the firmware, used voxilla's 3102/asterisk wizard as well as many other things I've found from Google. I have the 3102 on a static IP on the same subnet as the asterisk server. I don't even see the any attempted traffic when I watch iptraf during a call. Does anyone have any advice?

Here is a sip debug output when I try a call:
