Prices typically run $20-35 per user per month, though you'll find options from $10 to well over $50 depending on what you need. The best providers offer 99.999% uptime SLAs, number porting from your old carrier, and mobile apps that make your cell phone act like your office line. Whether you're a five-person startup or a 5,000-seat enterprise, there's a VoIP platform that fits.
