IP telephone points to any phone system which uses an internet connection for sending and receiving voice data.

How does IP Telephony work?
IP telephone systems use the internet protocol or digital protocols to transfer voice communication over the internet. If you are using an IP PBX system the data is transferred digitally on a local area network( LAN). It is then transferred to analogue voice signals and send to the PSTN. Due to the higher hardware and installation costs, IP PBAX no longer happens to be the existing solution.
Due to all of these factors, VoIP has emerged as the most widely used IP phone service.. It allows the business to cash in on the benefits of PBX features without hardware installation on-site.
The breakdown of how VOIP works
