NOTE:
If the Off-Premises extension uses virtual IP, on remote NAT equipment,
you will have to open the Signal and Media Ports as well as setup their Port
Mapping.
NOTE:
If the Blaze/Savanna Server is also under NAT, please activate
Blaze/Savanna Server’s NAT setting then open the NAT router’s UDP port
6046. Please refer to Chapter 3 System Configuration/General
