QUESTIONS
What is a VoIP phone?
A VoIP phone is a telephone that transmits voice calls over an Internet Protocol (IP) network rather than a traditional phone line. Most business VoIP phones connect to the company network via Ethernet, while some models also support Wi-Fi. To make and receive calls, the phone must be connected to a compatible VoIP service or SIP-based phone system.
What are the benefits of VoIP phones for businesses?
VoIP phones help businesses reduce communication costs, improve call quality and support flexible working. They also integrate easily with collaboration platforms such as Microsoft Teams and other unified communications solutions, making them a popular choice for modern organisations.
What's the difference between a VoIP phone and a traditional landline?
A VoIP phone routes calls over your business network or broadband connection, whereas a traditional landline relies on the public telephone network. This makes VoIP systems more flexible, easier to scale and better suited to today's digital workplaces.
Can you plug a VoIP phone directly into your broadband router?
Business VoIP desk phones require a correctly configured VoIP service or SIP account to operate. Simply connecting the phone to a broadband router is not enough. Your SIP credentials, network settings and telephony provider details must be configured before the device can make and receive calls.
What is PoE on a VoIP desk phone?
Power over Ethernet (PoE) allows both power and network data to be delivered through a single Ethernet cable. This simplifies installation, reduces cable clutter and eliminates the need for a separate power adaptor, provided you have a PoE-enabled network switch or compatible injector.
Can I use a headset with a VoIP phone?
Yes, provided the headset is compatible with your phone. Depending on the model, a VoIP phone may support RJ, USB or Bluetooth connectivity. If you handle a high volume of calls, it's worth checking headset compatibility before choosing the best VoIP phone for your business.
