Introducing the Switch VoIP App!

Built on the proven Acrobits VoIP Client

What is VoIP?

Very simply, VoIP is sending telephone calls over the Internet.  It stands for "Voice over IP".

What can VoIP do for me?

VoIP can dramatically reduce your telephone costs. Utilising a VoIP SIP connection over the Internet, you can connect to your telephone service, entirely free of connection charges, from anywhere in the world. As long as you have access to a reasonably good Internet connection, you can log in from anywhere on Earth and receive your calls just as if you were sitting at your office desk, for just 1.75 pence per minute - even if you're using our VoIP client on your mobile phone! You can also place calls at UK prices, regardless of where you are.
Data charges may apply for mobile use, depending on your mobile package.

How can I gain a VoIP service

  • Purchase any telephone number from Switch.
  • In the SwitchINS portal, purchase the "VoIP Upgrade". There is a one-off £10+VAT set up charge.
  • Download and install the Switch VoIP App, detailed on this page, or use any other SIP-capable softphone or SIP telephone.
  • Enter your username and password in your app or phone, and start using the service immediately!
