Setting the public IP address

If you are setting up an external IP extension, or the SIP server of a TalkSwitch VoIP network, you must configure a public IP address for the TalkSwitch system. Some service provider VoIP networks also require the TalkSwitch system to have a public IP address.

1.Set the Type of public address. Choices are:

•Dynamic public IP address — This is the default setting. Your ISP (Internet Service Provider) will assign different public IP addresses to your location. The TalkSwitch system will check its public IP address every few minutes. When the public IP address changes, the TalkSwitch system will automatically use the new one, in order to manage VoIP

calls properly.

If Dynamic public IP address is selected, the window completes the Current public IP address, and sets Public IP address-checker server name to checkip.talkswitch.com. This server runs an IP checker application that provides public IP addresses to TalkSwitch systems.

•Static public IP address — A static IP address is fixed. Your Internet Service Provider assigns the static IP address. If this location will have the SIP server for a TalkSwitch VoIP network, we recommend using a static IP address.

If Static public IP address is selected, the window allows you to enter the Current public IP address, and disables the Public IP address-checker server name box.
