Talkswitch Proxy; Public Ip Address - Talkswitch CT.TS005.003904 User Manual

TalkSwitch proxy

If your TalkSwitch system has multiple TalkSwitch units, the TalkSwitch Proxy area displays and
allows you to change the unit acting as local proxy. The local proxy handles Internet
communications for the TalkSwitch system. It establishes connections across the Internet, and
then routes Internet data to and from each TalkSwitch unit. The lowest numbered TalkSwitch
unit acts as local proxy by default.
The router must map the SIP, TFTP and HTTP ports to the local proxy. See Router port forwarding
on page 36.
1. If necessary, click the Change Proxy button. The Change Proxy window appears.
2. Select the TalkSwitch unit.

Public IP address

The Public IP address section allows you to set up Internet parameters so the TalkSwitch system
can communicate with other locations over the Internet.
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 five minutes. When the public IP address
changes, the TalkSwitch system will automatically use the new one. This allows it 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. You cannot change these items.
• Static public IP address — A static IP address is fixed. Your ISP 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.
2. If you selected Dynamic public IP address, enter the Fully qualified domain name (FQDN). Get
the FQDN from your ISP. The FQDN is only required if this location is the SIP server for a
TalkSwitch VoIP network, or has external IP extensions.
A DDNS (Dynamic Domain Name Service) provider such as www.dyndns.com matches your
dynamic IP addresses to your FQDN, so your TalkSwitch VoIP network or external IP phones
will continue to work when the IP address changes.
If you are using DDNS, ensure your router supports your DDNS service, and configure it to
update the DNS servers.
