Okay, I set:
CLI> sip set debug peer inbound-VoIP-Innovations
SIP Debugging Enabled for IP: 64.136.173.31
There was no response on the CLI>
I then exited the cli and ran tshark on eth0 and captured udp packets and saw the data from the provider. Somehow asterisk does not appear to be listening on eth0?
I'll post a link for you to look at the dump from tshark if you like. I just sent you a link via email.
