VoIP phones are phones connected to an IP phone system using LAN (Local Area Network) or the Internet instead of traditional phone lines. They connect to a PBX or VoIP phone service using IP networks—LAN or the internet. They convert voice into digital packets and send them over the network. On the receiving end, the signal is rebuilt into standard audio. This allows businesses to make calls globally without relying on copper phone lines.

IP phones are the backbone of any modern phone system. There are two main types:

Hardware IP Phones

These are desk phones that look like landline phones but connect over IP. They use SIP to communicate with the VoIP phone system. Common features: HD audio, BLF keys, USB/Bluetooth headset support, multi-line handling, and video on high-end models. Top brands based on customer reviews are Yealink, Snom, Fanvil, Cisco.

Softphones

Softphones are apps that run on desktops or mobile devices. They act like regular desk phones but need no hardware. They’re ideal for remote staff and small business teams. 3CX includes free softphones for Windows, iOS, Android, and the browser.

A VoIP phone service connects IP phones to the outside world using internet-based routing instead of analog lines. SIP handles signaling, RTP transmits voice. The system converts and delivers calls in real time. This reduces costs, simplifies scaling, and enables remote setups across offices.

Modern VoIP phones include: call hold/transfer/mute, voicemail, HD speaker/mic, headset support, presence display, menu navigation, USB ports, Wi-Fi, Bluetooth, and video (on premium models). Some models also support video conferencing and file sharing.

Softphone or Desk Phone?

Use softphones for remote staff. Use desk phones where hardware is preferred. Most businesses combine both. 3CX supports both options natively.

Compatibility

Check that the phone is SIP-compatible. 3CX offers plug & play provisioning for most ip phones.

Role-Specific Features

Agents need headsets. Managers may want touchscreens. Conference rooms need dedicated hardware.

Future-Ready Devices

Pick models that get regular updates and offer long-term support.

A working VoIP phone system includes: IP PBX software like 3CX, a SIP trunk or phone service provider, and compatible VoIP devices. 3CX supports major brands and includes automatic provisioning.
