Just a quick FYI..

ALL VOIP Adapters & Phones, Do not like Double Natting....

A lot of ATA's are "routers" as well, which means that they go thru NAT, 
and will not work behind another NAT router.

Most of these devices will get across a NAT router by registering to a 
SIP Proxy Server, which keeps track of the NAT Translations(Ports) 
(sometimes on some routers you have to adjust the NAT timeouts, for 
longer calls..) Sip Proxy Servers are not designed to keep track of NAT 
ports when the end device is going thru multiple NAT translations.
