Google’s calls are quite cheap, among the cheapest on the market, with 2 cents for some destinations like France and Argentina. These rates are much cheaper than those of Skype, which charge additional connection fees. However, Google’s calling minutes are more expensive than some players like Nymgo (as a matter of example), which offers calls for cheaper than a cent per minute.
Gmail calling is considered as a threat to Skype. Although it has a smaller subscriber base than Skype and isn’t as popular, it has the potential of challenging the number one VoIP provider. First, it offers calls for cheaper than Skype, then it brings along Google Voice’s arsenal features, like call recording, voicemail transcription etc. Also, it is incorporated with and email, which makes it better as a Unified Communications tool.
To receive calls within the service, you need a Google Voice number. Not so for making outgoing calls. Without a Google Voice number, your correspondent will see 760-705-8888 on their caller ID, which is Google default number for this service. If you have a Google Voice number, it will appear instead.
There is no need to install a separate application for the service. You just need to download a plugin for Gmail that will be installed and used within your browser. To make a call, just log into your Gmail account; you will be presented with a button to open the softphone and make calls.
