SIP/2.0 404 Not Found Inbound call help

I am unable to recieve a call inbound from my SIP trunk;

PrePBX 2.9 and Asterisks 1.6

outbound works fine.

my inbound route is any did / any cid
destation is my one and only extension.

Below is the sip debug from my full log during the failed call…BLUE SKY CLOUD is the inbound caller.

Can you tell from the log below why I am unable to get an inbound call to ring my ext?

You have no/wrong context defined for peer sul9024829689, you need to put context=from-trunk.
BTW, congrats on finding a provider who will authenticate their INVITE requests to you. It is rare.
