When various functions such as VoIP signal processing and gateway executed through IP

network in OfficeServ 7100 are executed in the Network Address Translation (NAT)

network, the conversion between the private IP address and public IP address may be

the information converted between the private IP and public IP and automatically convert

addresses for the smooth service. This function is only provided to OfficeServ 7100 MP11.
