VoIP setup guide: Skymesh supplied SPA 112 ATA

Here is everything you need to get started with your VOIP service, using your Skymesh-supplied Cisco SPA 112 ATA.

(If you’re using a different router, click here to see a list of supported equipment in our knowledge base, then select the router or ATA you’re using.)

Before you set up your ATA, we recommend connecting your computer and the SPA 112 ATA to a numbered LAN port on your router using an Ethernet cable.

Accessing your ATA

In order to access the ATA, you’ll need to obtain the IP address of the ATA.

1. Connect an analog phone to the Phone port of the ATA. (Line 1)
2. Press the star key four times: ****
3. After the greeting plays, enter the following sequence: 110#
4. Note down the numbers (IP address) the unit advises you. Your IP address will be a group of four numbers, like “192.168.1.50”

1. Open a web browser (e.g., Internet Explorer, Chrome, or Safari. Firefox will not work with the ATA).
2. Enter the IP address you discovered into the address bar using the following format: http://ip address:38081 or ip address:80
   (If you can’t find your address bar, press the “F6” button to highlight this section of your browser.)
3. The ATA will ask you for your username and password. Your username is ‘admin’ and the password is the admin password for this device.
4. You can also try using the username ‘admin’, and the password ‘admin’.
