Google Voice is a VoIP provider with a lot of value to offer. As part of Google Workspace, Google Voice integrates with other Google services like Gmail, Calendar, and Contacts. This can boost collaboration for organizations already operating within Google’s ecosystem, enabling teams to share contacts and calendars as well as streamline communication via calls, messages, and voicemails.

Even on the free plan, Google Voice has core features that are expected of a VoIP provider, like call forwarding, voicemail-to-email, and call screening. The free version is limited to a single user, but paid plans allow entire teams to collaborate using the software and access more advanced features.

It’s certainly a VoIP provider worth experimenting with, though it lacks the advanced features that other providers offer, like call queues, advanced analytics, call reporting, and logs for different users.

What makes a good VoIP provider?

There’s a lot to consider when choosing a good VoIP provider. The goal is to find a solution that strikes a balance between core features and service quality. Here are elements to keep in mind while assessing your choices:

  • Call quality: Crystal-clear audio and consistent service should be your focus when assessing call quality. Low-quality audio, frequent call dropping, and poor connections negatively impact the customer experience.
  • Reliability: Choose a provider with a strong track record of minimal downtime and redundant systems to minimize interruptions. Frequent interruptions can disrupt workflows and reduce focus, leading to longer wait times and frustrated customers. By minimizing interruptions, businesses can provide a more positive and efficient customer experience.
  • Features: A good VoIP provider should offer essential features like call forwarding, voicemail-to-email, and conference calling. A comprehensive suite allows you to tap into more advanced features like call recording, analytics, and integration with other tools.
  • Scalability: The provider should be able to handle your business’s expansion without compromising service quality.
  • Customer support: Evaluate how responsive the provider is in terms of support, speed, and effectiveness in addressing customer inquiries and issues.
  • Security: You’ll want a provider with robust security measures in place to protect your sensitive data. 
  • Integration: Check if the provider integrates with your existing business systems and applications. 
  • Pricing: Compare features and pricing to determine the best value for your budget.
  • Ease of use: Choose a provider with a simple and intuitive platform, and evaluate the ease of setting up your VoIP system and managing your account.
