The Internet has become an integral part of our life over the decades. Even right now, you’re reading this post using this awe-inspiring technological uprising. Voice chats and Video calls consist of a large part of our time spent on the internet. It’s quite a large market, and no surprise Linux is a significant player in this field.

If, however, you’re looking for Linux VoIP software, you won’t be disappointed too. Our experts have chosen the best options for both of them.
VoIP vs. Voice Chat Programs: Simplest Difference
We often see users scratching their heads when it comes to differentiating between Linux VoIP software and voice chat programs. To uncover this mystery, we’ll try to summarize the primary difference in concepts between these two.
A VoIP software is a program that lets users use the VoIP (Voice Over Internet Protocol) communication mechanism to make calls over the internet. This is a quite powerful technology as users can now make calls worldwide without paying a hefty amount to their mobile carriers.
On the other hand, voice chat software is used to send and receive voice messages across users in almost real-time. It’s quite similar to regular chat programs. But instead of sending text messages, you will send voice messages only. It’s particularly suitable for hardcore online gamers. They find them extremely useful when playing top-rated multiplayer games such as DOTA or PUBG.
