Cloud phone system features

A cloud phone system consists of key components that contribute to its overall functionality and performance. These components are essential to what makes a cloud phone service flexible, cost-effective, and reliable. Below, we list the key elements we typically find in most cloud phone providers.  

Virtual phone numbers: Cloud phone services offer a phone number upon subscription. Since it is independent of a location, a virtual phone number allows you to pick your desired area code. Most providers offer toll-free, vanity, and international number options for a small monthly fee.  

Call management: Call features vary across cloud phone providers, but they typically include capabilities that facilitate routing, forwarding, and scheduling of incoming calls. Call management in a cloud phone system commonly consists of an auto-attendant, ring groups, conference calling, voicemail, and business hours.  

Third-party integrations: Integrations streamline processes by allowing users to connect their third-party application to their business phone system. This makes it easy to pull up information without switching between different platforms. For example, CRM integration lets you quickly access customer data directly from the phone interface. 

Softphone: Compared to traditional desk phones, cloud phone systems enable users to use their preferred devices and take calls from anywhere. A VoIP provider offers a softphone that you can install on your desktop, tablet, or smartphone. Regardless of the device used, logging in on your softphone lets you access the same set of phone features and communication history.  

Benefits of cloud phone systems

Cloud phone systems are a worthwhile investment, regardless of your business size. When implemented effectively, they offer a significant impact on team communication, customer experience, and the company’s bottom line. Let’s take a look at these advantages.

  • Cost-effective: A cloud-based telephone system eliminates the costs associated with installing and maintaining on-premise phone systems. Instead, you’ll only pay a minimal monthly subscription fee to access your business phone service, while the provider will handle the upgrades, configuration, and security measures. 
  • Mobility: With cloud-based telephone systems, all you need is an internet-connected device to send and receive calls. This benefits remote teams wanting to stay connected while working from home. You can also apply changes to your call flow directly from your browser and keep the same phone number regardless of your location. 
  • Better customer service: Professional phone features like auto-attendant and call queues ensure a smooth caller experience by reducing wait times and routing calls to the right department. Call analytics generate valuable insights into the customer journey, while integrations provide in-call access to customer data. 
  • Efficient team communication: Most cloud phone services integrate voice with other communication channels like chat and video conferencing. They also offer collaboration tools, such as file attachments, calendar sharing, and whiteboard. This creates a unified workspace, where teams can access the same files and communication tools on one platform.  

Choosing the best cloud phone system

Cloud phone systems are critical communication tools for any size business, as they provide a range of features that enable efficient communication, collaboration, and customer experience. While choosing the right provider can be a tough call, knowing your specific needs and budget can help you make an informed decision that aligns with your business objectives.

Vonage is our overall best cloud phone system due to its customizable phone features, making it a great fit for businesses with unique communication needs. Teams with unpredictable call volumes all throughout the year should consider Zoom Phone, as it allows mixing and matching of metered and unlimited call plans. 

RingCentral works best for enterprise-level businesses with sophisticated communication needs like advanced analytics, robust integrations, and extensive call routing capabilities. Its close competitor, Nextiva, integrates its phone system with customer experience tools, helping sales and support teams streamline customer interactions. 

Cash-strapped teams with an existing Google Workspace subscription are better off with Google Voice’s budget-friendly phone system. However, if you’re new to VoIP and value simplicity, we strongly recommend Grasshopper’s virtual phone system.
