DiaVoice vs Google Voice
Google Voice is one of the most searched business phone solutions on the internet. The word "free" tends to do that. But if you are a small business owner evaluating Google Voice as your phone system in 2026, there are some things you need to know before you commit.
What Google Voice Actually Is
Google Voice is a cloud-based phone number service built by Google. The personal version is free and has been used by individuals for years. The business version — Google Voice for Google Workspace — is a paid product that requires an active Google Workspace subscription on top of the Voice plan itself.
So right away, "free" gets complicated.
The Real Cost of Google Voice for Business
Google Voice for business starts at $10/user/month — but that is before you factor in the required Google Workspace subscription, which starts at $7/user/month. So the real starting price is $17/user/month minimum, before taxes and fees.
And that is for the Starter plan, which is missing features most businesses actually need — no auto-attendant on the base tier, no ring groups, no call recording, limited support.
DiaVoice DiaPBX starts at $20/user/month with no Google Workspace requirement, no hidden subscription dependencies, and full PBX features included from day one.

What Google Voice Does Well
It is fair to acknowledge: if you are already deep in the Google Workspace ecosystem, Google Voice integrates cleanly with Gmail, Google Calendar, and Meet. The interface is clean and intuitive. For a very small team that lives entirely in Google's world and has simple phone needs, it works. But "it works" is a low bar for a business phone system.
