I concur with you. Either that or the phones have STUN enabled. Does x-lite work properly when you put it in the same private network as your polycoms? If it does then this is a clue that Polycom is doing something like STUN. If it doesn't then it points to your router. One more thing. You say that your x-lite registration looks like: <sip:[email protected]:28436;rinstance=b83c40108342c5fb;x-sipX-privcontact=74.2.3.4%3A28436> This does not appear normal to me. Basically, the contact should show the public IP address of the x-lite whereas the x-sipX-privcontact should show the private IP addresss. In your case, they are the same thing - this is indicative of some sort of misconfiguration but not sure where. Please review http://wiki.sipfoundry.org/display/xecsuserV4r0/Remote+User+NAT+Traversal to make sure your setup is sound.
