Aastra 6753i
In this guide we will go through configuring the Aastra 6753i in order to register it to the Callcentric servers so that you will be able to place and receive calls using your Callcentric account. Before moving forward please ensure you have properly added the device to your network and that you have acquired the proper IP address. The phone should be turned on and running and you should have access to the device's configuration menus.

We recommend that you read each step through in its entirety before performing the action indicated in the step.
STEP 1 Logging into your device
First we will acquire the IP Address of your device, if you haven't already done so. You can acquire the IP of your device by:

1. Hitting the Options buttons
2. Scrolling down to and selecting Phone Status
3. Selecting IP&MAC Addresses

Your IP Address should be shown to you, along with other network information. If your IP Address is 0.0.0.0 please make sure that your device is properly connected to your network.

Once you have acquired your IP login to your device by using http://IP_ADDRESS/. If this is your first time logging into your device you may be asked to enter a username and password. By default this should be:

User: admin
Password: 22222

If you do not have this information then you will need to either reset or acquire this login information. Unfortunately we would not be able to provide support on this topic. You may however visit the Aastra support page for your specific device.

Once logged in you should see a screen similar to the one below:



STEP 2 Configuring your Callcentric account

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