Google Voice vs Vonage
Google Voice and Vonage are both leading contenders in VoIP solutions, each offering distinct features for businesses. However, KrispCall is seen as a strong competitor compared to these providers.

It is recognized for its seamless integration with the Google Workspace ecosystem, making it a preferred option for companies already using Gmail, Google Calendar, and other Google applications.
It provides an easy-to-use, cloud-based telephone system that works across various devices, with essential features such as calling, voicemail, and texting.
Vonage
Vonage Business Cloud is a cloud-based UCaaS platform that provides voice, video, and messaging services for small to mid-sized companies. It integrates with third-party applications and includes IP-PBX capabilities, video conferencing, and collaboration tools.
With tools like the Vonage app, users can make calls, send texts, and manage client interactions via a softphone interface.
Additionally, it offers robust CRM integrations, including Salesforce, to streamline customer engagement and sales workflows.

Google Voice vs Vonage Comparison
Google Voice
Google Voice has three pricing plans and is usually included with a Google Workspace subscription ($10–$30/user/month). The Starter plan costs $10 /user/month and supports up to 10 users.
Video conferencing is available in Google Workspace, with participant limits of 100 to 1,000 and features like meeting recording, noise cancellation, and breakout rooms, depending on the plan.
Vonage
Vonage offers three plans. The Mobile plan costs $13.99 /user/month based on team size. Video conferencing is included only in the Premium ($20.99/user/month) and Advanced ($27.99/user/month) plans.
Advanced features like an AI virtual assistant, call transcription, call queues, and a business inbox can be added to any plan.
Google Voice
Google Voice is more affordable, especially for small teams using Google Workspace, with lower entry-level pricing and video conferencing included.
Vonage is pricier but better for businesses that need advanced call features.
Google Voice
Google Voice is simple and affordable, especially for Google Workspace users. The free version includes basic calling features, while paid plans add call routing, forwarding, and transcription.
However, it lacks advanced features such as auto-replies, call recording, toll-free numbers, team collaboration, and MMS support, making it less suitable for larger teams.
Vonage
Vonage offers over 50 features across all plans, including desktop and mobile apps, unlimited calls and SMS, and integrations, while advanced features are only on higher-tier plans.
Though Vonage is a strong business that needs advanced call management, its MMS setup is complex, and toll-free numbers are limited to the US.
Vonage
Vonage wins for its broader feature set and integrations, making it better for businesses that need advanced call management.
Google Voice is cheaper but too limited for teams with heavier communication needs.
Google Voice
Google Voice’s integrations are limited. It primarily works with internal Workspace apps such as Gmail and Google Drive. This limits connection with other CRM and other business tools.
Integrating with other tools in the future is difficult, which can restrict business growth and impact customer experience.
Vonage
Vonage offers several integrations at first glance, including Google Workspace, Zendesk, and Slack.
However, you need the Premium plan or higher to access CRM integrations like Microsoft Dynamics and Salesforce. But if you are outside the US, some platforms, including Microsoft Dynamics, are not available.
Vonage
Vonage provides more integration options than Google Voice.
However, KrispCall is even better, offering 100+ integrations and greater flexibility for growing businesses.
Google Voice
Google Voice provides 24/7 live support, a user forum, and a knowledge base. However, it does not offer live chat or email support, nor does it provide onboarding assistance.
Vonage
Vonage provides live chat, email support, phone support, and a user forum with a knowledge base. It also offers optional onboarding support for an additional cost.
Vonage
Vonage wins for customer support because it offers more support channels and onboarding assistance, making it easier for businesses to get help when needed.
