VoxSun vs Microsoft Teams Phone

THE TRUTH: The VoIP pricing model is broken

Most businesses never have their entire team on calls at the same time. But traditional providers charge you as if they do

Microsoft Teams Phone

Per Seat Model

You pay for full capacity

Every employee = one paid line — even if they’re not on a call

You pay for everything — used or not

£8,466 / month

200 employees = 200 lines billed

You’re paying for unused capacity

VoxSun

Per Line + BOOST Model

You pay for real usage

Lines are shared across users based on actual call activity

You only pay for what you actually use

VoxSun increases your capacity momentarily for FREE

Extra capacity activates instantly — automatically — and at no cost. Then disappears when demand drops

Same team. Same usage. Up to 50% lower cost.

How VoxSun BOOST Actually Works

Your capacity adapts in real time — automatically, and for free

Your team doesn’t stop — your system scales with them.
Step 1 — Base
2 calls active
Only 2 simultaneous calls based on your base plan
Step 2 — Detection
3 calls active
System detects increased demand in real time
+1 Line
Step 3 — Boost
4 calls active
Extra lines activate automatically — no extra cost

No waiting. No missed calls. No extra charges.

Built for real business usage — including peaks

Your activity isn't constant.

Sometimes, more people are on calls at the same time.

VoxSun adapts instantly — at no extra cost.

When call volume increases:

  • The system automatically activates additional capacity
  • No delay
  • No manual setup
  • No extra charges

When activity goes back to normal:

  • The extra capacity disappears

Business activity is not constant. Pricing shouldn’t be either

You don't pay for peak usage.

You only pay for real usage.

Traffic spike? No problem. VoxSun temporarily expands your capacity — automatically and for free — then scales back when demand drops.

Not all communication platforms are built the same. here's what actually impacts your business

VoxSun Advantages

  • 64% saving (£65,504/year) vs a full Teams deployment for 200 users

  • No calling plan required — unlimited USA + Canada included
  • BOOST free auto-scaling — Teams has no equivalent
  • BoostMyDeal AI included on Pro — Teams has no sales automation at any price

  • Live in under 24 hours — no M365 admin, no SBC, no IT project
  • EU markets: unlimited calling vs Teams 1,200 min/user hard cap

Why Businesses Leave Microsoft Teams Phone

  • Embedded in M365 — compelling for Microsoft-standardised organisations

  • Deep native integration with Dynamics 365, SharePoint, Azure AD
  • Teams Phone on E5 includes enterprise compliance and security tooling
  • Free number porting vs VoxSun £14.99/number (waived with contract)
