Google has started updating Hangouts for desktop with possibility to make phone calls as it has been possible to do with Google Talk integrated in Gmail. The measure is being very well received by those fortunate who have already reached the new software package. And it is that if at some point you wanted to consider this new service from Mountain View as the substitute and integrator of all the previous messaging and communication services, this function could not be left out.
Many of us uninstalled the Hangouts browser plugin, as well as its integration in Gmail, after testing them, since they did not provide anything new that we could not do with the previous options. Especially those of us who had money in our account for these purposes. Now it seems that it will change between other improvements.
The interface will change slightly with respect to the design that we now see. We can also Hangouts with multiple participants and even multiple phone numbers at the same time. To all this must be added the possibility of add sound effects such as laughter or applause to enhance your expressiveness, something that adds to the option of putting emoticons that already preceded us.
To make phone calls, in Gmail you just have to go to the New Hangout box and to its right we will see the symbol of a phone. If you still don't have Hangouts installed in Gmail, go to the chat area and activate it by clicking on your image and giving it a try.
In Google+ and in the plugin for Chrome, we must use the drop-down menu and look for the option Call a phone that will appear to us.
The option is expected to be extended globally in the coming days. Nothing has been said about the incorporation of this capacity in Android. Meanwhile if you want to make phone calls using your funds in Google Voice, you I recommend this tutorial.
