IP phones connect to your phone service via the internet, using an ethernet cable or WiFi connection.
What are VoIP Phones?
IP phones, also known as VoIP phones, look similar in appearance to traditional desk phones, but are far more advanced. Like small computers, all the on-board features are applications, and the display and buttons can be customized by the user.
IP phones are wired using Ethernet cables and connect to an IP-based phone system, whereas traditional desk phones use an analog cable and typically connect to analog or legacy digital phone systems.
What allows IP phones to be so powerful is that they use an Internet protocol called SIP (Session Initiation Protocol) to send and receive audio.
