Is that correct that Asterisk was sending to a RFC1918 address? From
your description of your setup, it seemed that the backend Asterisk
servers themselves had 1918 addresses, and your Polycoms would have
public addresses.

In that case, the Asterisk instances might be using their 1918
addresses in packets to the Polycoms. To correct that, the Asterisk
instances would need to use something like STUN or a preset public IP
address in its SIP configuration.
