How Much Does a Phone System Cost for Small Businesses?
Cloud vs. on-premise: all costs compared.
A phone system costs small businesses $5-50 per user per month (cloud/VoIP) or $2,000-15,000 one-time (on-premise). Cloud phone systems like RingCentral, Grasshopper, or Dialpad are the most affordable option for SMBs: starting at $20/user/month with no hardware investment. Important: a phone system does not solve the problem of missed calls. If nobody picks up, the phone still rings into the void. For after-hours availability, you also need an answering service or AI assistant.
What is Phone System?
A phone system (PBX) manages a business's telephony: call routing, hold queues, transfers, and voicemail. Modern cloud phone systems (VoIP) replace traditional hardware with software. They improve internal communication but do not solve the availability problem: when all employees are busy or off the clock, even the best phone system cannot help.

Hidden Costs
Hardware Costs
IP phones cost $50-300 per workstation. Headsets $30-150. Cordless handsets $80-200 each.
Call Charges
Unlimited domestic calling plans cost $5-15/user/month extra. International and mobile calls are billed separately.
Maintenance and Updates
On-premise systems need regular maintenance. Cloud systems include updates, but premium support costs extra.
Phone System is worth it when…
- Your team needs internal telephony (transfers, conferencing, hold queues)
- You have multiple employees who answer calls
- CRM integration and call recording are business-critical
- You need professional number management (extensions, ring groups)
Phone System is not worth it when…
- Your main problem is that nobody answers the phone (availability)
- You are a solo operator or have a small team of 1-3 people
- You need 24/7 availability without staffing
- Automated appointment booking and FAQ handling are more important than internal telephony

FAQ
Phone system vs. AI phone assistant: which do I need?
A phone system manages your telephony (transfers, ring groups, hold queues). An AI phone assistant steps in when nobody can answer. They solve different problems. Many businesses use both: a phone system for day-to-day operations and an AI assistant as a backup.
Which cloud phone system is best for SMBs?
For small businesses (2-10 employees), RingCentral (from $20/user) or Grasshopper (from $14/month) are strong choices. Both offer reliable uptime and solid feature sets. Dialpad and 8x8 offer more advanced features but come at a higher price.
Can I connect Vokaro with my phone system?
Yes. Vokaro integrates via SIP trunk or simple call forwarding into your existing phone system. If nobody picks up after X seconds, the call is automatically routed to Vokaro.
Do I still need a phone system if I use Vokaro?
As a solo operator or small business (1-3 people): probably not. Vokaro handles all incoming calls that you do not answer yourself. Starting at 5+ employees with internal telephony needs, a phone system makes sense with Vokaro as an availability backup.
Availability, Not Just Telephony
A phone system alone does not solve the problem of missed calls. Vokaro does.
