Sorry, I wasn't talking about running the sipXecs server without putting it behind a firewall - I was just talking about putting the sipXecs server on a DMZ without NAT. The firewall will still limit inbound connections so that they are only allowed from our ITSP.

Given that sipXecs cannot be dual-homed, if the sipXecs server is given a public IP address, does it create issues to have the phones behind NAT? Yes, they need to be behind a firewall that does not have an ALG turned on. Your are well-adviced to run a firewall in front of sipx though. Why would you do such a thing? If so, then do the phones need non-NAT access to the ITSP, or just non-NAT access to the sipXecs server? Neither. They will traverse NAT through their local firewall. Remote users need to be configured in sipx but not server behind nat.
