VoIP technology uses the internet to transmit phone calls instead of traditional copper phone lines.

Upgrading to a VoIP phone system is cost-effective as calls use the existing internet connection and so calling costs are greatly reduced, especially for international calls. IT infrastructure, maintenance, and equipment costs are also reduced after the initial system upgrade.

A VoIP phone system also offers several features that may not be available in traditional telephony systems such as conference calls, instant messaging, automatic call forwarding, voice mail to email, and easy integration with CRM systems.
