Proxy Server Realm: This is used for gateway SIP account authentication in a SIP server. In most cases, the gateway can automatically detect your SIP server realm. So you can leave this option as blank. However, if your SIP server requires you to use a specific realm you can manually type it in here. If you fail to make a call, please contact your VoIP service provider.

TTL: Enter the desired time interval at which the gateway will report to your Proxy Server.

SIP Domain/Use Domain to Register: Enter the correct SIP domain to avoid registration failure (it is not necessary to set this with some Proxy Servers). If you enable “Uses Domain to Register” the VoIP Gateway will register to Proxy with the domain name you filed. Alternatively, the VoIP Gateway will register to a Proxy with the IP it resolves. If you fail to make a call, please contact your VoIP service provider.

Bind Proxy Interval for NAT: This function is able to keep the binding is existed when VoIP Gateway is behind NAT and SIP Proxy is not able to keep the binding.

Initial Unregister: After rebooting, it is unregistered first and then do the general register process.
