VoIP: XLite SoftPhone: Getting Started

A "softphone" is a piece of software that you download to your computer, which combined with FreeVirtualNumbers enables you to experience VoIP technology and experiment with set up and call quality. You will also, ideally, need a headset such as the Plantronics 400 - however, if you have speakers and a microphone with your computer, these will do adequately (although call quality may slightly suffer as the "pickup" from a microphone isn't as good as a headset solution).

We recommend the X-Lite Softphone which may be downloaded free from Xten at: http://www.xten.com/index.php?menu=download.

When you have downloaded it (by selecting the X-Lite v3.0 for Windows file from the linked directory above), you must configure it - this is a fairly straightforward process and is described briefly below.

After installation and on running the program it will display the following screen.

This should be partially covered by the following

X-Lite SIP Accounts screen

In which case press Add. If the screen above does not come up then Right click the phones screen which will display:

X-Lite Softphones Settings Menu

Pressing SIP account options will get you the SIP Accounts screen above.

Pressing Add or if there is one already there Properties will show the following screen

X Lite SIP Account Configuration screen
  • Display name: Enter your name as you wish it to be seen as the CallerID for those people you call
  • Username: Your FreeVirtualNumbers extension number
  • Password: Your FreeVirtualNumbers password for that extension
  • Authorization user name: Your Free Virtual Numbers extension number again
  • Domain: [lease enter sip.freevirtualnumbers.co.uk or if instructed to by email lon-pbx-N.freevirtualnumbers.co.uk [Where N can be any number from 1 to 7.]
  • Domain:
    • Select: "Register with domain and receive incoming calls"
    • Select "Send outbound via [*] proxy"
    • In the "Proxy address" box, enter nat.freevirtualnumbers.co.uk:5082 [or nat1 or nat2 as indicated in any email sent to you]
  • Dialing plan: #1\a\a.T|+x.T;match=1;prestrip=2;match=2;prestrip=1;pre="00";
    This dialing plan allows you to use "+" as an international prefix (i.e. +441164960000 for the UK number 0116 4960000 as it will automatically replace the "+" with "00")

Then click on the Topology tab at the top.

X-Lite Topology tab

and select Use local IP address at the top. Click apply on the bottom right hand corner and we would expect it to immediately work with the Free Virtual Numbers Voice Over IP system

Dial 160 to try the echo test. You should hear everything you say echoed back to you.

Audio Problems?

If after configuring the software you get one way audio problems these can be resolved by changing the following settings:

Options... Advanced... Audio Codecs and removing all but one (e.g., G711 uLaw) from the list of enabled codecs

Dial ***7469 (SEND)

Filter for Honor: Change the value of Honor first codec to 1 save and restart the application. [by closing and saving when asked]
