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 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.
