VoIP or IP telephony (also called Voice Over Internet Protocol) converts analog audio signals into digital data over the internet that allows users to conduct online calls. Unlike traditional circuit-switched networks, VoIP helps companies create a unified voice and data network. Another benefit of this protocol is that it reduces network infrastructure costs due to its ability to connect voice services through private networks and broadband. Without costing anything extra unlike how traditional phone company’s would require, VoIP allows for return calls, three-way calls, caller ID, repeat dial, call transfers, and call waiting features.
Using a VoIP service also gives you the freedom to choose the device you can take and make the calls from: ATA, Computer-to-computer, IP Phones or via WiFi Phones. An ATA (Analog Telephone Adaptor) is the most common way VoIPs are used. This device connects your computer or internet connection to a standard phone. Computer-to-computer connections eliminate the need for long distance calls and can be done through an internet connection, a cable/DSL modem, speakers, microphone, and a sound card. As for IP Phones, these specialized phones look similar to typical phones but have ethernet connectors. These phones connect directly to your router while WiFi Phones connect to any WiFi hotspot and don’t require a direct connection to a router.
