Guys,
I'm having some issue setting up my home UC520W. I factory reset the device. Now I set up my SIP Trunk Provider. I can make outgoing calls just fine. but the Incoming calls is what is not working. I'm not sure why! I need some help. Here's a snippet of the debug message I get.

Matches your called SIP number, translates it to x101, and sends it to my phone.
Hope it helps.
Since my UC system was using a Private address I passed through the DHCP straight so it can get a public address. Then there was an ACL and the allow incoming calls from the provider. God It was such a big headache.
