A three-way call is a conversation that starts between two parties, and they add a third person later. One of the participants can dial a friend to join the call. Three-way calling is a VoIP feature that lets you call more than one phone at the same time. Once you’ve dialed the number of the person to join the call, you can merge them into the call. You can repeat this for up to six participants with Nextiva. This is also known as an N-way call. Since there’s no need to set up a conference bridge, it’s best for quick collaboration in small groups.
