How to configure Linksys SPA3102 without a hassle

Linksys SPA3102 VoIP Configuration

GENERAL INFORMATION

The Linksys SPA3102 is a device similar to the Linksys PAP2/T line of devices in appearance and configuration. In addition to the similar appearance, the Linksys SPA3102 also adds extra features not present in the PAP2/T such as an FXO (Foreign Exchange Office: allowing you to use a normal PSTN line or PBX line for redundancy in case of an outage on your ISP…etc) and a built-in router allowing you to share your internet without the need for a standard router/switch. The Linksys SPA3102 is reliable and relatively inexpensive and can be considered by individuals who want the extra PSTN functionality for their specific environments. Linksys SPA3102 RESOURCES

The configuration information below is based on firmware version 5.1.7(GW), which is the latest version as of this writing. Before we proceed please make sure that your Linksys SPA3102 is powered on and that you have an ethernet (RJ45) cable connected with one end to your router/modem/gateway and the other end to the blue port on the back of the Linksys SPA3102. You will also want to connect a regular telephone (RJ11) cable to the phone port labeled “Phone”. Once you have verified this please continue configuring your device with the instructions below. We recommend that you read each step through in its entirety before performing the action indicated in the step. STEP 1a If this is your first time configuring your Linksys SPA3102 then you will need to first find the IP address of your device and then enable HTTP configuration. To do so have a pen and paper ready to write down the IP address. Once you’re ready do the following:

Pick up your telephone handset
Dial ****, do this even if you hear a busy signal
You will hear a message – “Linksys configuration menu. Please enter option followed by the pound key…“, then enter 1 1 0 # on your phone.
You will now hear a message giving you the IP address of your PAP2 such as – “192.168.001.100“. Write this number down

Do not hang up yet, as of now you will need to enable web-based configuration since by default the web-based configuration for the WAN port is disabled. To enable web-based configuration: You will hear the menu prompt again after acquiring the IP address. After hearing the prompt dial 7932# followed by 1# then 1 when asked to save the change. You should now have the IP address for your Linksys SPA3102 as well as the ability to configure your device through your web browser. Continue onto Step 2 below. STEP 1b If you have already enabled web configuration you simply need to acquire your device’s IP address in order to configure it. If your computer is not connected to the yellow port on the back of the Linksys SPA3102 then please do the following:

Pick up your telephone handset
Dial ****, do this even if you hear a busy signal
You will hear a message – “Linksys configuration menu. Please enter option followed by the pound key…“, then enter 1 1 0 # on your phone.
You will now hear a message giving you the IP address of your PAP2 such as – “192.168.001.100“. Write this number down

Else if your PC is connected to the yellow port on the back or your Linksys SPA3102 then the SPA3102 IP should be 192.168.0.1, unless you changed the subnet in your advanced configuration. Once you have acquired your device’s IP continue on to Step 2 below. STEP 2 Now that you have your device’s IP address simply open your favorite web browser and enter the IP address in the address bar and press enter. Please note: You do not need to enter the leading zero’s ( 0 ‘s ) in the IP address. For example, if you heard “192.168.001.010” you should change this to “192.168.1.10” By default, the Linksys SPA3102 does not have a username/password associated with it. If you are prompted for a username and password please enter the one you configured. Once logged in you should see a page such as the following:

STEP 3 We now want advanced access to this device so that we may make the proper configuration changes. First click on Admin login from the right side of the page, then click on Advanced:

We are now ready to enter your Switch2Voip account information as well as properly configure your time and DNS servers. Continue to Step 4. STEP 4 Click on WAN Setup and then make the following changes:

Set your Primary DNS server to a public DNS server such as 208.67.222.222. You can also set your Secondary DNS server to a public DNS server such as 208.67.222.220, 4.2.2.1… etc
Make sure your DNS Server Order is set to Manual, DHCP
Set your Primary NTP Server to 0.pool.ntp.org, or your preferred working NTP server. You can also add a Secondary NTP Server if you wish

The time servers are indicated in the picture below: “time.nist.gov” and “time-a.nist.gov” are two primary time servers provided by the US Government for public use. The time server primarily will be used to show the correct time on your phone’s caller-id display when you receive a call.

Once done scroll to the bottom of the page and click on Submit All Changes to save your changes. Once the page reloads click on the Voice tab at the top of the page and go to Step 5. STEP 5 Click on the tab labeled SIP from the menu at the top.
