Google said Sept. 1 Gmail users made more than 10 million calls through its new Call Phones from Gmail feature since it launched a week ago.
Launched Aug. 25, Call Phones from Gmail lets users place calls to contacts directly from Gmail. Calls placed from Gmail in the United States and Canada are free and start at 2 cents per minute outside those countries.
The tool, which requires Google's voice and video plug-in, lets users click a Call Phone link. This opens a window with a dialer keypad. Users may began typing the names of their contacts to call, or enter a number and click to dial the contact's mobile phone or landline.
Some of Gmail's 180 million or so users tried out the service, resulting in 1 million calls placed from Gmail in 24 hours.
That pace picked up, with more than 10 million calls lodged in the first seven days since the VOIP tool's release, Google Voice Product Marketing Manager Michael Bolognino said.
Google Voice users using Call Phones from Gmail have their personal Google Voice number displayed as their caller ID, thanks to Gmail's integration with that phone management application.
Bolognino offered tips Google Voice users can employ to set up Gmail to receive calls via their Google Voice number.
Google Voice users may navigate to Google Voice, click on settings and check the box next to Google Chat in their list of forwarding phones.
This will allow Voice users to make and receive calls to their Google Voice number from Gmail and access features such as call screening.
