Cisco SPA112 ATA

The Cisco SPA112 is the newer version of the Linksys PAP2T ATAs which some people are using at home. We prefer it to the PAP2T, although it does not support pulse dialing phones.

Set Up

Step 1: Plug in your SPA112 as outlined in the instruction booklet, connected to your broadband router, and a telephone.

Step 2: Turn on the SPA112 and wait until the light next to "Line 1" is lit up. Then dial **** (four asterisks) this should give you the automated voice menu

Step 3: Dial 110# The PAP2T will then read its IP address out to you (eg Write this down!

Step 4: On your computer, open a web browser (internet explorer, firefox, chrome etc) and type the IP address into the address bar. This should bring up the login page for the ATA. The default Username is "admin" with a Password of "admin"

Step 5: The first screen you will see is the "Quick Setup" screen. Enter the following details:
Display Name: (we provide this by email when you request an account)
User ID: (we provide this by email when you request an account)
Password: (we provide this by email when you request an account)
Dial Plan (optional): xxx
Click "Submit" to save the settings

Step 6: Click on Network Setup (top menu) then Time Settings (left menu), and enter the following information:
Time Zone (GMT) England
Time Server Address Set the dropdown box to "Manual" and enter
Click "Submit" to save the settings and you are all done!

Your ATA should now be configured to work with the DFR Asterisk system.

How to test it

We recommend the following tests, to make sure your ATA is working.

Test 1 : Try dialling 400 to reach our speaking clock.

Test 2 : Try dialling 401 which is an echo test number. This should echo your speech back to you so you can tell if audio is working in both directions.

If both of those tests are successful you are good to go! If either of them fails, check your settings carefully and make a note of the date/time at which the test failed so that we can investigate further.

Changing the admin password

You may want to change the Admin password. To do this, click on Administration (top menu), User List (left menu) then click on the row for the admin user. It may be useful to write the admin password on the bottom of the ATA so you do not lose it!
