What’s The Difference between PBX Systems and VoIP?

Many business owners wonder about the difference between PBX systems and VoIP. So what are the differences between the two? PBX systems use what we call “trunk lines” that are linked from the local phone operator to your office. Thus, PBX systems need physical lines to work. VoIP, however; is what we call “Voice over Internet Protocol.” VoIP transmits voice waves over the internet making a VoIP system less expensive and more flexible – all you need is a computer and a network in the company. Overall, VoIP is more popular due to its ease of use and lower costs. PBX systems are still employed by corporate bodies, however; many switched to VoIP already.
