Over the years Google has expanded the Gmail communication.
Recently they have updated with their Google Voice and Video
calls,Today Google has provided with a relaxation of the restriction
and allow Gmail users to make or receive multiple calls in Gmail.
If you’re in a call and make a second one, your first call will be put
on hold while you talk on your new call. You can switch between calls by
pressing the “Resume” button on the call you want to talk on, which
will automatically put the previous call on hold.
Receiving incoming calls while you’re in another call is just as easy:
you’ll receive a notification of the incoming call and can choose to
accept it or not. If you take the new call, the previous call will be
put on hold.
Whether you make a second call or not, you can now put any call on hold —
useful in case you need to talk to someone in the room or grab
something off the stove. Just press the “Hold” button and then “Resume” to start talking again.
This feature works across all call types (voice, video, and phone); the only restriction is that a maximum of two outgoing calls to physical phones can be placed at once.
