VoIP: Standard Settings for most SIP Phones/Devices
Make sure that your SIP Phone is turned on and connected to an IP Router or Modem. If you are using a softphone make sure that your PC is connected to the network.
In your phone's configuration menu there should be an option to define a "SIP Server", "SIP Registrar" or "SIP Domain" value. Set the value to: sip.freevirtualnumbers.co.uk if you are a Single Line user.
If you are a Centrex user you will be sent a welcome email detailing which settings you should use (which will be in the format lon-pbx-X.freevirtualnumbers.co.uk )
For SIP Authentication, set your SIP User ID or similar to your FreeVirtualNumbers.co.uk VoIP ID (eg 9300100) and set SIP Password or similar to your six-digit Password provided in your activation email.
If you have an "Outbound Proxy" setting, set this to: nat.freevirtualnumbers.co.uk:5082. Alternatively, if this setting allows you to define the port in a separate field, set the IP Address to: nat.freevirtualnumbers.co.uk and the port number to: 5082. Note:
There will be no need to use the outbound proxy if your adaptor/phone has a static public IP address assigned to it.
Confirm the settings by reloading or rebooting your phone. Dial 160 to access the echo test utility to check that the phone is working correctly.
If you encounter any problems, make sure that your IP Router or ISP is not blocking any traffic, specifically on ports 5060 and 5082. Also ensure that the router is not blocking UDP traffic. You can contact your network administrator or ISP for more information.
