Verizon SIP Trunks, No ring on inbound and OOS channels 1

[andynetcon]

So I'm able to see the calls come in. Here's the trace

That 10.81.1.5 address is the WAN port. That 172.30.215.17 address is what Verizon gave me as my proxy. I've got another site that's set up identically save for the difference in the IP schemes and it's working just fine. Over here I get no ringing on the inbound and all of my SIP channels show as out of service. Any ideas? This is an 8.1.63 box.

On the SIP Line Tab, uncheck "Check OOS".

I'm not that fried. Problem was actually that I had to set NAT Type to Open Internet in Network Topology. Thanks!
