Cisco 7940/7960 and NAT using SIP

    Anyone know of a way to get the Cisco phones to communicate with the
    TFTP server or register through a NAT, like any regular broadband
    router? All the Polycoms I've tested seem to work perfectly even through
    multiple NATs with no special configuration of any kind but I'll be
    damned if I can even get port forwarding to work for the Cisco phones.
    They won't even show up in Sylantro ComManager for registration.

    Any suggestions are greatly appreciated.

    Thanks,
    Brandonb
