PC and Mac: X-ten Lite

You can install this softphone on a PC or Mac (there others similar for smartphones), allowing you to use your computer as a telephone, with your existing microphone or through a headset with a microphone connected to your soundcard. Using service, you can place phone calls to any landline or mobile phone in the world at our extremely low rates.

We will show the step-by-step setup only for X-Lite free softphone as it is the most widely used and deployed solution and it is also available on platforms other than Windows, such as Mac and Linux.

First, you need to download and install X-ten Lite. The program can be found inside a ZIP archive with the password
Please note that later versions have significantly reduced functionality compared to version 3:
 X-Ten Lite ver 4
X-Ten Lite ver 3

For X-Ten Lite version 4, click on the Softphone menu and choose Account Settings. Fill in YourUserID and YourPassword and enter (or whichever city is shown in My Services) YourDomain field. Enter for the Display name whatever you want to appear in Caller ID when you call somebody (outgoing calls). The number to dial for Voicemail is *97.

On the X-Ten Lite program version 3 (oldversion), click on the MENU button (on the right of CLEAR and on the left of the green button) or right click somewhere on the phone.

Select System Settings, SIP Proxy, Default. And enter the following info:

  • Enabled: Yes
  • Display name: Your name (this will show on Caller ID display when calling)
  • Username: YourUserID (from Control Panel - My Services)
  • Password: YourPassword from MyServices
  • Authorization user name: leave this empty
  • Domain/Realm = SIP Proxy: (YourDomain from My Services)
  • Click the "domain" radio button in version 3

Please see the samples above.

Testing the Service

To test the service dial 4443 for an echo test, which is a service which tests the quality / latency of your connection.


  • If the phone fails to login, please take the time to double check your configuration as above.
  • If everything appears to be correct, the problem may be your firewall
  • If you are running Windows, try disabling the built in firewall.
  • If you have an external firewall try opening SIP ports
  • If everything else fails and your router / Firewall supports DMZ, try putting the machine with the softphone on the DMZ; only try this last
  • Ports:
    • SIP signalling port (UDP listen) = 5060 RTP/RTCP ports (UDP) = 8000 – 8001
    • RTP/RTCP port (UDP listen) = 10000 - 30000 (depending on your sip phone)
