The service allows free calls to any phone in the U.S. and Canada and rates to other countries.
Google was quick to introduce formally the function call of IP telephone in Gmail that was in testing a few days ago. The service is integrated into the chat module webmail after installing a plug-in available on this page. A function for the moment only available in the United States and Canada.
Calls to any phone in and between these two countries are free, "at least until the end of the year," says Google.
2 cents per minute for France
International calls are charged at reduced rates ranging for example up to 0.02 dollars per minute to France. Users who have an Google Voice account may use the telephone number they were assigned to receive calls and identify themselves when making a phone call from Gmail.
Google says it intends to expand this service to other countries but gives no date.
