Was this issue ever resolved? I am experiencing the same problem at a Customer Site.

Do you have CME behind NAT? If yes, what type of device is doing NAT ?

Always include relevant traces when reporting problems.

Yes, uc500 behind nat. nat is running off a simple netgear box supplied by ISP. I have got it working by adding a loopback with the outside ip on the uc500 (an ip spoof) but it doesnt feel like the best thing to do. What really had me tearing my hair out is that an older configuration worked without the loopback...but I can't find a difference that would account for that.
