Office phone system FAQs
An office phone system is a central hub for your business communications, letting your team make, receive, and route calls across multiple lines and extensions. A cloud-based virtual phone system adds video meetings, team messaging, and voicemail transcription in one place.
A traditional landline routes calls over copper wires and on-site private branch exchange (PBX) hardware, while VoIP routes calls over your internet connection. VoIP typically costs 40–60% less per month and lets you add or remove lines in minutes instead of scheduling a technician.
VoIP is the technology that carries voice calls over the internet, while UCaaS bundles VoIP calling with video meetings, team messaging, and file sharing in one subscription. Choose VoIP instead of UCaaS for voice-only needs, or choose UCaaS if you want calling, meetings, and messaging in a single workspace.
Cloud-based VoIP plans for small businesses typically run $20–$35 per user per month, billed annually, covering unlimited domestic calling, messaging, and video calling. Legacy PBX systems cost more upfront and add ongoing maintenance contracts.
Look for unlimited domestic calling, a main business number with extensions, voicemail-to-email, and an auto-attendant, which cover most day-to-day needs for teams up to 50 people. Larger teams should also look for video conferencing, mobile apps, and call analytics—all of these are included in a single RingEX plan.
Yes, porting your number to a new provider is standard and typically free, with most transfers completing in 2–10 business days. Your old service stays active during the switch, so you won't miss calls.
Most small businesses can set up a cloud phone system in under a day by signing up, porting a number, adding users, and configuring call routing through a web dashboard. Larger teams with complex call flows, like multi-level menus or call queues, may need a few extra days to fully configure.
