Product Manual


Configuring Uniden EXP1240
The setup guide below is based the running on firmware revision IPDECT/03.55/B0023/04-Nov-2016 15:41, if you are running a different software version, some menus/settings may be different. These instructions are also based on using the Uniden EXP1240B in its factory default configuration, which obtains a dynamic IP address automatically from your router using DHCP. This guide also assumes that your handset is already paired with your base station. For information on configuring your base station with a static IP address as well as how to pair your handset with your base station, please refer to the base station's user manual.

In this guide we will go through configuring the EXP1240B in order to register to the Callcentric servers so that you will be able to place and receive calls using your Callcentric account. Before proceeding, please ensure that you have properly added the device to your network by connecting it to your router or gateway.

We recommend that you read each step through in its entirety before performing the action(s) indicated within the step.

Note: Although this device supports many advanced features/options; this guide will only detail the specific settings which are required to establish basic connectivity between your EXP1240B and our service. If you need additional assistance with any specific issue please let us know.
STEP 1 Retrieving the Base Station's IP address
Before you can log into your base station's web configuration, you will first need to retrieve the IP address of your base station. Assuming that both your handset and base-state are powered on; from your handset, press the menu key. From there, dial * 4 7 *; which should bring up the "IP search" utility, which should display both the MAC address of the base station that the handset is currently associated with, and more importantly, the IP address.

On your computer, open up a web browser (such as Firefox, Chrome, Safari, etc...) and enter the IP address you've received on your handset into your browser's address bar (as an example, if you've received the address 192.168.0.2 on your handset; specify 192.168.0.2 on your browsers address bar). You should be presented with a login dialog box, prompting you to enter in your device username and password. By default, the base station should be using admin as both the username and password. Once you have specified those credentials, you should be presented with a status screen similar to the screenshot below:



Note: If you do run into any issues pairing your handset to your base station, please refer to the EXP1240B's user manual for additional information.

STEP 2 Defining a Server
From the side menu bar on the left side of the configuration page, locate the section Servers; and from there, click on the Add Server link as indicated by the screenshot below:



From the server section of your configurations, please enter in the following settings, similar to the screenshot below:

STEP 3 Adding an extension
From the side menu bar on the left side of the configuration page, locate the Extensions section; and from there click on the Add Extension link as indicated by the screenshot below:



From the extension section of your configurations, please enter in the following settings, similar to the screenshot below:



SettingValue
Line nameYou may specify any name on this field
ExtensionThis is either the default extension 1777MYCCID OR 1777MYCCIDEXT, where 1777MYCCID is the 1777 number assigned to you by Callcentric and EXT is the three digit extension you are trying to register this UA to.

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

You cannot register to your account using only the extension number.
Authentication User NameThis is either the default extension 1777MYCCID OR 1777MYCCIDEXT, where 1777MYCCID is the 1777 number assigned to you by Callcentric and EXT is the three digit extension you are trying to register this UA to.

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

You cannot register to your account using only the extension number.
Authentication PasswordEnter 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.
Display NameYou may specify any name on this field
ServerSelect the server alias that you've defined for our service from step 2 of our setup guide.


Click on the Save button to apply/save your changes.

STEP 4 Associating your Handset with your extension
Now that you've defined an extension on your base station, you will need to point your handset to that extension using your handset's unique identifier (IPEI number). To retrieve your handset's IPEI number, from your handset, press the menu button; navigate to the Settings section and select Status. This should provide information about your handset such as firmware revision, battery level and more importantly the IPEI number; it should be formatted in the fashion xx:xx:xx:xx:xx (as an example 02:AE:FF:FF:FF).

Next from the extensions page of your base stations configuration interface, under the IPEI column, click on the idenfier (which by default is set to FFFFFFFFFF); as shown on the screenshot below:



From there, enter the IPEI number that you were presented with on the handset, in the IPEI field of the configuration interface; similar to what's presented on the screenshot below:



Click on the Save button to apply/save your changes. Doing so, should bring you back to the Extensions Page of your base station's web configurations. From here, click on the check box next to the extension that you've created and click on the Register Handset(s) link as indicated by the screenshot below:



Next, from your handset, press the menu button and navigate to the Connectivity section, and select Register. If you are prompted for an access code, by default the access code should be 0000.

Once you have done so, your handset should be associated with the extension you've created and your phone's registration should be complete. To check the status of your registration, from your base station's web configurations, visit the Home/Status section, and you should see a "Status: OK" next to extension that you've defined, similar to the screenshot below:



STEP 5 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).
