Frequently Asked Questions

Can I use a business phone system on my personal cell phone?

Yes, all three platforms offer mobile apps that turn your personal smartphone into a business phone. You can make and receive calls using your business number, access voicemail, and manage settings — all without revealing your personal number. This is one of the key advantages of VoIP business phone systems over traditional landlines.

What equipment do I need for a VoIP business phone?

At minimum, you need an internet connection and a device (smartphone, computer, or desk phone). For softphone use (computer-based calling), any modern computer with a microphone and speakers works. For desk phones, most providers support popular models from Poly, Yealink, and Cisco. RingCentral offers certified desk phones with device insurance on higher-tier plans.

How long does it take to set up a business phone system?

Grasshopper can be set up in under 30 minutes — pick your number, record your greeting, and you're live. Nextiva and RingCentral take 1-2 hours for initial setup, with number porting adding 5-14 business days. All providers offer onboarding assistance, and RingCentral provides dedicated implementation managers for larger deployments.

Can I get a toll-free number?

Yes, all three providers offer toll-free numbers (800, 888, 877, 866, 855, 844, 833). RingCentral includes toll-free numbers on all plans with competitive per-minute rates. Nextiva offers toll-free numbers with unlimited incoming calls on higher-tier plans. Grasshopper supports toll-free numbers on all plans with included minutes.
