The service, which works by using WiFi in place of a mobile operator, is compatible with any network and will allow customers to make cheaper calls abroad.
"SmartCall will stretch the home telephone cord all the way to wherever you might be, whether in a coffee shop in Cornwall or on a beach in Bali," said Virgin Media executive Graeme Oxby.
SmartCall does not require users to be on the Virgin Media mobile network, but a landline account with the service provider is required as well as an iOS or Android handset running the app.
The application is currently in the testing stage and will be rolled out to select customers on an "exclusive" basis over the coming weeks, before its full release in early 2013.
Virgin Media will release the SmartCall app for iOS and Android at launch, with more platforms expected to follow.
