1What's the difference between single handset and multi-handset Grandstream cordless systems?
Single handset models work for small offices or home use, while multi-handset systems let multiple people answer calls simultaneously and work better for larger teams. Multi-handset systems cost more upfront but scale easily—you can add extra handsets later as your business grows.
2How far does the wireless range typically work, and does it matter for my office layout?
Most Grandstream cordless phones have a range of 100-300 meters in open space, but walls and interference reduce this significantly. Check your office floor plan and test coverage before buying if you have a large or multi-floor space.
3What battery life should I expect, and how does it affect daily use?
Standard models offer 10-15 hours of talk time and 100+ hours of standby, which is enough for a normal workday without charging. If your team takes long calls or moves around constantly, look for models with extended battery claims.
4Do I need a specific phone system or PBX to use a Grandstream cordless phone?
Most Grandstream cordless models work as standalone devices connecting directly to any standard phone line or VoIP service. Check compatibility with your existing system before buying if you're adding to an established setup rather than starting fresh.
5When is it worth spending more on a premium Grandstream model versus a basic one?
Premium models offer better build quality, longer battery life, and advanced features like conference calling or integrated directories—worth it if your team relies heavily on mobility. Basic models work fine for occasional cordless use or backup handsets in small offices.
