1What's the difference between a desk IP phone and a softphone?
A desk IP phone is a physical device that connects to your network and works like a traditional office phone, while a softphone is software you install on your computer or mobile device. Choose a desk phone if you need dedicated hardware and better audio quality, or a softphone if you want flexibility and lower upfront costs.
2How many lines do I actually need on an IP phone?
Most small businesses and individuals need 1-2 lines, while larger offices benefit from 4+ lines to handle multiple calls simultaneously. Check your current call volume and team size—if you rarely take more than one call at a time, a single-line phone will do fine.
3What internet speed do I need for IP phones to work properly?
Each IP phone typically needs 80-100 kbps of bandwidth per call, so a standard broadband connection (5 Mbps or higher) handles multiple phones without issue. If you have slow or unstable internet, you'll experience poor call quality and dropped connections.
4Is it worth paying more for a phone with a built-in Bluetooth headset?
Built-in Bluetooth adds convenience and flexibility, especially if you move around your office or take calls while multitasking. If you're stationary at a desk most of the time, a cheaper phone paired with a separate headset works just as well.
5What should I check about compatibility before buying an IP phone?
Confirm the phone works with your VoIP service provider (SIP protocol support is standard but double-check) and that your network setup can support it. Also verify whether it needs Power over Ethernet (PoE) or a separate power adapter based on your office infrastructure.
