    The log is receiving a number of entries like the following that I do not know how to reconcile. The extension does not "appear" to register and currently no out bound calls are made.

    How should I interpret these entries.

    it says about NAT.
    The NAT is (at least) "port restricted" which is not suitable for PBX...
    For PBX, the "full cone NAT" is mandatory. Otherwise - PBX will have intermittent problems with remote devices
