Free Conference Call service software

Here I have shared some of the free conference call service software that can be used on PC, Android, and iPhone. These are the best tools that anyone can use on their system, so let’s start!

Google Hangouts

Google Hangouts is a unified communications service (chat by text, voice, and video – presence management), both face to face and in exchange for several within a group. Hangouts is closely linked to Gmail. The Hangouts client apps are available on Android and iOS.

Google Hangouts can also be used by businesses as a platform to chat with their customers or partners. Hangouts have indeed an “On Air” function which allows Gmail users to broadcast video calls on Youtube in real-time (like a TV channel). The tool has gained popularity, for example in the context of professional training seminars.

Google Hangouts is the replacement for the previous features included in Gmail and Google+, then grouped under the name of Google Talk. Hangouts can also interface with Google Voice – VoIP and line centralization service (mobile, landline, over IP) – to make phone calls directly from a computer.

Key Features

  • Google has developed the Google Hangouts Chat app to be able to use all the messaging features from a smartphone, further improving teamwork from all types of media.
  • Professional Google Hangouts messaging includes several bots that are present to facilitate synchronization between the different G Suite applications.
  • Google Hangouts is a free group chat service that can gather up to 150 participants in its chat version and ten for video calls.

When talking about Skype, instant messaging is not the first thing that comes to mind. Microsoft’s VoIP application is more widely known and used for voice and video calls. But the publisher intends to change this by introducing a series of new features on this kind of service. First, there will be a draft mode similar to what is found on email applications. When a Skype user starts typing a message but does not send it, it will be kept in the conversation and marked as a draft so that they can come back and complete it.

Another practical function is the possibility of marking messages so that they are classified in favorites, which will help to find them more easily. Catching up on other chat services, Skype will offer the preview of photos, files and videos before sending them. And in the case of grouped sharing of several contents, only the first will be displayed in preview while the rest will be hidden behind a “+” button in order to avoid overloading the conversation window. These new features are being deployed on all versions of Skype.

Key Features

  • It is easy to set up a videoconference and to exchange directly with colleagues and collaborators. With screen sharing, information is easily transmitted and the entire group that has joined the video chat can view and comment on documents shared by a user.
  • The tool is equipped with an automatic translation module, a background blur and a call transfer. The application also has instant messaging that combines the basic functionality expected from a chat, such as a possibility of attaching files, GIF animations or reacting to messages with emoticons.
  • Skype allows you to make audio or video calls without going through a telephone line, which is particularly useful for contacting physically distant people near and abroad for free.
