Despite predictions Google Fiber had no interest in offering customers landline telephone service, Google has quietly begun testing a new residential voice service called Google Fiber Phone that appeared to be powered by its Google Voice service.

Google hoped to keep the trial confidential, but one of its subscribers shared their invitation with the Washington Post:

We are always looking to provide new offerings to members of our Fiber Trusted Tester program which gives you early access to confidential products and features.

Our latest offering is Google Fiber Phone, which gives you the chance to add home phone service to your current Fiber service plan and offers several advanced features:

Please be aware that testing Google Fiber Phone will require a service visit in which a Fiber team member will come to your home to install a piece of equipment. If you’re selected for this Trusted Tester group, we will be actively seeking your feedback – both good and bad – so that we can improve Fiber Phone once we launch it to all of our customers.

Please remember that the Trusted Tester Program gives you early access to features which are not yet available to the public, so please help us keep this confidential.

Thanks,

The Google Fiber Team

The feature set sounds almost identical to Google Voice, which offers free phone service. For the first time, Google is prepared to allow customers to port existing landline numbers to its phone service. Previously, Google Voice customers could only port a cell phone number or select a new number to start the service.

Google Fiber has only sold single or double-play packages of Internet and/or television service. Customers looking for telephone service had to select a third-party provider like Vonage or Ooma or be technically proficient to get Google Voice service up and running with Voice over IP equipment. Including Google Fiber Phone would allow Google to sell a triple-play package.

The technician visit required is likely to involve wiring Google Fiber’s beta test phone line into a home’s existing telephone wiring, which will let customers use their current home and cordless phones.

Google has not announced a price for the service, but there is every chance it could come free with Google Fiber, which starts at $70 a month for 1 gigabit broadband service.

Despite the increasing frequency of announcements promoting new Google Fiber cities, Google’s currently operating fiber network remains modest. In October 2015, Bernstein Research estimated Google Fiber passed about 427,000 homes and 96,000 business locations, primarily in Kansas City and Provo, Utah, according to Multichannel News. Bernstein estimated Google Fiber has about 120,000 paid customers nationwide.
