DID-Based Routing with Asterisk
Cisco ATA 186/188

The Cisco ATA 186 / 188 is a reliable telephone adapter that works well with the Callcentric service when placed behind your broadband internet router.

The Cisco ATA 180 series documentation and support can be found here.

CONFIGURING Cisco ATA 186 / 188
Please note: The instructions for configuring the Cisco ATA 186 / 188 listed below apply to version 3.2.00 (041111A) of the Cisco ATA SIP software. If you are running a different version some settings and menus may be different.


Connect your router with the supplied Ethernet network cable to the Cisco. Now connect your phone to the port labeled "PHONE 1" on the back of the Cisco. Finally plug the supplied power cable into the Cisco.

Wait 60 seconds after plugging your Cisco in.

Pick up the phone connected to the Cisco and push the function button located on the top of the Cisco.

Have a pen and paper ready. You will hear the welcome message, then enter 2 1 # on your phone. You will now here a message giving you the IP address of your Cisco such as - "" write this number down and hang-up the phone.

Open a web browser on your computer such as Internet Explorer and enter the IP address you heard in step 4 as the address and then /dev (I.E. where you would normally enter

For example, the configuration page for a Cisco ATA with the IP address is:

Please note: some browsers will require you to remove leading zero's ( 0 's ) in the IP address. For example if you heard "" you should change this to "".

You should now see a page that looks like this:


Enter the password for the Cisco in the password field. The default administrator password for the Cisco is "admin" (without quotes).

After entering the password you should see a screen that looks roughly like this:

Click the option SIP PARAMETERS in the menu on the right hand side of the page.


You will now see a screen that looks like this:

For example: 17770001234101 would register to extension 101 on account 17770001234.

You cannot register to your account using only the extension number.
PWD0:Enter your extension SIP Password here. Your extension SIP password is the password you created for the extension you are trying to use. You may edit the SIP password you wish to use in by logging into your My Callcentric account and clicking on the Extension menu link and then modifying the appropriate extension.

Click the apply button.


You will now see a screen that looks like:


Your Cisco will reboot after you click the apply button. Please wait at least 60 seconds for the unit to finish rebooting. Once the unit has finished rebooting you should no longer see the light on top of the Cisco blinking red. If the light is no longer blinking red then your unit is configured and ready to make calls, please continue to the next step.

If the light on the top of the Cisco is still blinking red, please wait 2 minutes and then unplug the power, wait 10 seconds and plug it back in. If after another 2 minutes the light continues to blink red please verify that the settings you entered into the Cisco in step 9 are correct, and that your internet connection is currently up and running.


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
011 + the country code, area code, and number for calls worldwide (you may also use 00 instead of 011).
