Does the router not use network address translation (NAT/NAPT)?
If the router uses address translation techniques (e.g., NAT/NAPT) to convert between global and local IP
addresses, VoIP communications between the IP-EXT card and IP-PT cannot be carried out effectively.
Therefore, the
routers used to access the IP network must not use NAT/NAPT. Generally, NAT and NAPT are
features that are available with routers.
