Google Voice Service

Google Voice is a telephone system that offers services for voice and text messaging only for Google account holders in the United States. For other countries, you may require the use of Google Hangouts, which does not provide a free phone number and does not allow you to send free text messages.

- - Automated attendants
  - Call transfer
  - Integration with Google Calendar and Google Meet
  - Phone number ownership
  - Ring groups
  - Voicemail transcription
  - AI to summarize calls

Besides lacking robust customer service, Google Voice has limited capabilities compared to Microsoft Teams Voice.

Pricing Breakdown

Pricing is a key factor when choosing between Microsoft Teams Phone and Google Voice, as costs can vary based on your business size and calling needs. Teams Phone operates as an add-on to Microsoft 365 plans, while Google Voice offers straightforward tiers within Google Workspace.

Tier	Microsoft Teams Phone	Google Voice
Base	$10 (Standard) + M365 $6	$10 (Starter, 10-user cap)
Mild	$17 (Domestic minutes)	$20 (Standard)
Top	$34 (Intl)	$30 (Premier, unlimited)
Trial	30 days	14 days

Teams Phone requires a base Microsoft 365 license (starting ~$6/user/monthly), pushing total costs to $16+ for basic calling, ideal if you’re already invested in the ecosystem. Google Voice bundles neatly at $10–$30 with no hidden base fees, but caps features and users on lower plans, often requiring upgrades for SMB growth.

Which VoIP provider is better: Google Voice vs Teams Phone

While Google Voice shines for small teams or solos with easy setup, low cost, multi-device flexibility, and Google ecosystem sync. For enterprises handling sensitive data or operating at scale, Microsoft Teams Phone stands out with robust compliance features like HIPAA and GDPR support, ensuring your calls and records meet strict regulatory standards, critical for industries like healthcare, finance, or energy sectors. It also delivers a 99.999% uptime SLA, meaning near-zero downtime even during peak usage, which keeps global teams connected without interruptions.

Direct Routing takes this further by letting you connect Teams Phone to your existing PBX or SIP trunks from preferred carriers, bypassing Microsoft’s Calling Plans for full control over international rates, custom numbers, and hybrid setups. This flexibility scales seamlessly for thousands of users, perfect if your organization workflows demand enterprise-grade reliability over Google Voice’s lighter US-focused approach.
