If you've heard the term "VoIP" but aren't quite sure what it means — or whether it matters for your business — you're in the right place. This guide explains VoIP in plain English: what it is, how it works, and why so many businesses have already made the switch.
VoIP in Plain English
VoIP stands for Voice over Internet Protocol. The short version: instead of sending your voice through a traditional copper phone line, VoIP converts your voice into digital data and sends it over your internet connection. The person on the other end hears it just like a regular phone call — often with better clarity.
Think of it like the difference between mailing a physical letter and sending an email. Both deliver a message; one uses an old physical infrastructure, the other uses the internet. VoIP is the "email" version of phone calls.
How Business VoIP Actually Works
When you speak into a VoIP phone or app, your voice is digitized, compressed into small data packets, and transmitted over your internet connection to a cloud server. The server routes those packets to the other party — whether that's another VoIP user, a mobile phone, or a traditional landline. The round trip happens in milliseconds, which is why VoIP calls sound as natural as any other call.
The "cloud" part means the PBX (the system that manages call routing, voicemail, extensions, and features) is hosted by your provider rather than sitting in your office as an expensive hardware box. You pay a monthly fee and access everything through a web portal and softphone app.
What's Included in a Business VoIP System?
A modern hosted VoIP service like Broadtela includes features that once required expensive hardware or per-feature add-ons:
- Auto-attendant (IVR) — "Press 1 for Sales, 2 for Support..."
- Ring groups — ring multiple phones when a customer calls one number
- Voicemail-to-email — transcribed voicemails delivered to your inbox
- Call recording — for quality assurance and compliance
- Time-based routing — different behavior after hours, on weekends, and on holidays
- Mobile softphone app — your business number on your personal smartphone
- Conference bridges — multi-party calls without extra fees
What Internet Speed Do You Need?
Each simultaneous VoIP call uses approximately 100 Kbps of bandwidth. A typical 25 Mbps business internet connection can handle 100+ simultaneous calls with room to spare. For most small businesses, your existing internet connection is completely adequate for VoIP.
If you run a call center or have bandwidth-intensive operations, a managed internet connection with Quality of Service (QoS) ensures voice traffic is always prioritized — preventing choppy calls even during heavy data usage.
Is VoIP Reliable Enough for My Business?
Enterprise-grade VoIP providers like Broadtela maintain 99.9% uptime SLAs on geo-redundant infrastructure. Your calls route through multiple data centers, so a single server issue never interrupts your calls. Because VoIP works over your internet connection, having a secondary internet connection (4G/LTE backup, for example) gives you complete redundancy.
The bottom line: for the vast majority of businesses, VoIP is more reliable than legacy copper phone lines, which depend on aging infrastructure that no carrier is actively maintaining.
How Much Does Business VoIP Cost?
At Broadtela, hosted VoIP is $24.95 per seat per month — all features included, no contracts. Compare that to typical traditional phone line costs of $50–$80 per line, and most businesses find they save 40–60% immediately after switching. The switch also eliminates hardware maintenance costs, technician visit fees, and the frustration of being locked into a carrier contract.
