Public IP
A Proxy/NAT device is sometimes used in a Client/Registrar SPP voip system where the registrar voip is in a private network but serves client voips on a public network. The Proxy/NAT device isolates (protects) the registrar voip from the public network.
In such cases, you must check the “Enable SPP Proxy/NAT device” checkbox in the Phonebook Configuration screen of the Registrar voip. The private registrar voip can then function with the client voips using the public IP address of the Proxy/NAT device. You must enter this address in the Public IP Address field.
