2 TALKSWITCH VOIP NETWORK CONFIGURATION GUIDE
CONNECTING TO A NETWORK
Each location requires a high-speed connection to the Internet or private IP network that is sufficient
for VoIP calls.
Connecting to local and IP networks
Set up a LAN (local area network) with an Ethernet switch, router, and modem or gateway. The
Ethernet switch can be integrated into the router. Connect a computer to the LAN for configuring the
phone system and other equipment. Use the provided RJ-45 Ethernet cable to connect the phone
system to the LAN. To ensure reliability, all equipment should be connected to a UPS (uninterrupted
power supply).
Figure 1: Local and IP network setup
Confirming network capacity
Ensure the LAN in each location has a reliable high-speed broadband connection to the Internet or
private IP network. The quality of VoIP calls, especially on mixed voice and data networks, depends
on high data-transfer rates across the network. The limiting factor is the upstream bandwidth to the
ISP (Internet Service Provider). ‘Lite’ broadband connections (128 Kbps or less) are not suitable for
simultaneous voice and data traffic.
To test the VoIP call capacity based on your Internet connection speed, perform the test found in the
support section at http://global.talkswitch.com.

CONFIGURING IP ADDRESSES
Setting the system IP settings
Each unit must be configured with a local IP address. These addresses are used to direct VoIP calls to
the appropriate location.
1. In the Management Software, select the IP Configuration page. By default, Obtain IP and DNS
information automatically is selected and the area shows IP addresses from the router.
2. Change Obtain IP and DNS information automatically to Use configured IP and DNS information in
order to lock in the IP addresses.
3. In some cases, the System IP Settings area may be blank because your router has not delivered
the IP addresses. If so, enter the following IP addresses from your LAN administrator:
a) Enter a static IP address for each unit in the Unit IP address boxes.
b) Enter the Subnet mask for the LAN. This address determines the subnet that the unit IP
addresses belong to.
c) Enter the IP address of the Default gateway on your network. A gateway is a hardware device
that connects the office network to the Internet. The router may act as default gateway.
d) Enter the IP address of the Preferred DNS server. DNS is a service that is used to resolve a
domain name to an IP address. The router may act as DNS server.
e) If applicable, enter the IP address of the Alternate DNS server.

Setting the public IP address
If you are setting up an external IP extension, or the SIP server of a multi-branch VoIP network, you
must configure a public IP address for the system. Some service provider VoIP networks also require
the 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 system will check its public IP
address every few minutes. When the public IP address changes, the system will automatically
use the new one, in order to manage VoIP calls properly.
• 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 multi-branch 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.

2. If you selected Dynamic public IP address, enter the Public domain name. Get the public domain
name from your ISP.
A DDNS (Dynamic Domain Name Service) provider such as www.dyndns.com matches your
dynamic IP addresses to your public domain name, so your multi-branch VoIP network or external
IP phones will continue to work when the IP address changes.
If your router supports DDNS, ensure it supports your DDNS provider, and configure it to update
the DNS servers.
If your router does not support DDNS, download one of the applications specified on
www.dyndns.com. To update the DNS servers, the application needs to run on a PC connected to
the same LAN as the phone system.
3. If you selected Static public IP address, enter the Current public IP address from your Internet
Service Provider. Leave the Public domain name box blank.
If the phone system is not behind a router, or if a private virtual network is used, the public IP
address is the local IP address of the unit acting as local proxy.
Note that it will take up to one minute for the new static public IP address to take effect.
4. Record the Current public IP address or the Public domain name.
If you are setting up an external IP extension, you will need the public IP address or public
domain name of the system.
If you are setting up a multi-branch VoIP network, the multi-branch profiles of the SIP clients
must be configured with the public IP address or public domain name of the SIP server.
6 TALKSWITCH VOIP NETWORK CONFIGURATION GUIDE
CONFIGURING THE ROUTER
The Router Port Forwarding area of the IP Configuration page displays the type of gateway device
(i.e. the type of router), the IP address of the gateway (i.e. router), and whether router configuration
is required.
A router is a gateway between the local area network and the Internet. Most routers have a firewall
to block unwanted data from the Internet. For voice data to reach the phone system through the
firewall, port forwarding is required.
If you are setting up external IP extensions, a multi-branch VoIP network, or a VoIP service that
doesn’t handle port forwarding, port forwarding is required.
If port forwarding is required, and your router supports uPNP (Universal Plug and Play), ensure uPNP
is enabled. The system will use uPNP to automatically set up port forwarding, and the Automatic
(uPNP Enabled) link will appear. No router configuration is required.
If port forwarding is required but your router doesn’t support uPNP, or automatic port forwarding
doesn’t work, the Manual port mapping required link will appear. You will need to configure the
router as described below.
1. Select the IP Configuration page.
2. If required, click the Manual port mapping required link. The Manual Port Mapping window
appears. It lists the packet type, port number, IP address and protocol of each required port.
