Google has opened its Voice service to all users, but said that availability is limited to the US for now.
Google Voice offers a single-number communications service, and has been in a trial in the US for the past year.
The company said that the service offers low priced international calls, but that UK users will have to wait a little longer for a local option.
Craig Walker and Vincent Paquet, Google Voice product managers, said in a blog post that the service has moved beyond the "invitation only" stage.
"We're proud of the progress we've made with Google Voice over the last few years, and we're still just scratching the surface of what's possible when you combine your regular phone service with the latest web technology," they wrote.
"It's even more amazing to think about how far communication has come over the last couple hundred years. To put things in context, we created this infographic to visualise some recent history of human communication and how Google Voice uses the web to help people communicate in more ways than ever before."
Google UK was unable to provide any further information on a UK rollout.
