VoIP phones are connected to an IP phone system using LAN (Local Area Network) or the Internet. VoIP converts the standard telephone audio into a digital format which can be transmitted over the internet and also converts incoming digital phone signals coming from the internet to standard telephone audio. A VoIP telephone allows users to make phone calls using VoIP, to any softphone, mobile or landline. A VoIP telephone can be a simple software-based softphone or a hardware device.
Hardware SIP phones look very similar to traditional analog phones however are developed to be used in IP networks. Softphones or smartphone clients, on the other hand, are software applications that are used on your computer, tablet or smartphone and behave exactly like a normal IP telephone; allowing you to carry out regular functions such as making and receiving calls, as well as some additional functions such as video conferences, presentation giving and more.
Most IP phones use SIP (Session Initiation Protocol), whether they are hardware IP phones or softphones. Some well known manufacturers of IP phones include Fanvil, Htek, Snom and Yealink. 3CX includes high performing and feature-rich softphones for Windows and Mac as well as smartphone clients for iOS and Android for free.
3CX’s software PBX supports auto provisioning of a wide range of popular IP phones sold worldwide. Furthermore, 3CX also provides legacy support to numerous older or proprietary devices including Cisco.
