STEP 1

Connect your device's power and ethernet cables.
For users with the SPA112:
Connect your router with the supplied Ethernet network cable to the SPA112's internet port. Now connect your phone to the SPA112's Phone 1 port. Finally plug the supplied power cable into the SPA112.
For users with the SPA122:
Connect your router with the supplied Ethernet network cable to the SPA122's Internet port. Temporarily connect your computer to the SPA122's Ethernet port using a Ethernet network cable (this is necessary as the SPA122 will not allow you to access the web configuration interface without changing the default web password). Now connect your phone to the SPA122's Phone 1 port. Finally plug the supplied power cable into the SPA122.

STEP 2
|
Wait 60 seconds after plugging your SPA112/SPA122 in.
Pick up the phone connected to the SPA112/SPA122 and dial the * key on your phone 4 times.
For users with the SPA112:
Have a pen and paper ready. You will hear a message - Enter a menu option, then enter 1 1 0 on your phone. You will now hear a message giving you the IP address of your SPA112 such as - "192.168.001.010" and write this number down.
For users with the SPA122:
Have a pen and paper ready. You will hear a message - Enter a menu option, then enter 2 1 0 on your phone. You will now hear a message giving you the IP address of your SPA122 such as - "192.168.001.010" and write this number down.

STEP 3
|
Open a web browser on your computer such as Firefox or Chrome and enter the IP address you heard in step 4 as the address (I.E. where you would normally enter www.yahoo.com).
Please note: some browsers will require you to remove 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".
You should now see a page that looks like this:
Enter the default credentials in the appropriate fields. For the SPA112/SPA122 please specify "admin" as the username, and "admin" as the password (without quotes).

That's it! You can now make a phone call.
You can make a test call to 17771234567, or if you are signed up for one of Callcentric's rate plans you
can place a call to a traditional landline or mobile phone by dialing either:
1 + the area code and number for calls to the US
Or
011 + the country code, area code, and number for calls worldwide
(you may also use 00 instead of 011). |
Cisco's SPA112 (SPA1XX) series of products are the successors to the popular PAP2 and PAP2T line of adapters. These telephone adapters are reliable and work with the Callcentric service when placed behind your broadband internet router.
