Zoom Phone is a fully integrated cloud phone system built for modern teams. Whether you’re already using Zoom for meetings or just need a flexible business phone solution, Zoom Phone gives you crystal-clear call quality, AI-powered productivity tools, and a user-friendly admin experience, all in one platform. 

With native integrations, call summaries and next steps, voicemail prioritization, team SMS thread summary (Power Pack add-on required) and seamless call-to-meeting transitions, you can simplify communication, reduce tech sprawl, and keep your team connected wherever they work. Here are some of the standout features of Zoom Phone:

• Clear, reliable call quality: Zoom Phone uses HD voice, echo cancellation, noise suppression, and packet‑loss concealment to deliver consistently clear, professional calls (even on imperfect networks).
  
  
• Fast, hassle‑free deployment: The platform is ready to use right out of the box with mobile and desktop apps. It includes a centralized admin portal where you can manage users and devices, all without needing on-premises hardware.
  
  
• Seamless escalation to video meetings: With one click, you can take a voice call and instantly escalate it into a Zoom meeting for video or screen sharing. This feature simplifies workflows and avoids added friction from tool sprawl.
  
  
• Flexible carrier options with BYOC and number porting: Zoom lets you bring your own telecom carrier or easily port existing numbers, so you can adopt their cloud phone system without disrupting current phone contracts.
  
  
• Better efficiency: Features like auto attendants, call queues, call transfer/forwarding, shared lines, and delegate controls help you route calls intelligently and reduce wait times.
  
  
• Security and reliability designed for the enterprise: Zoom Phone is a trusted communication system, thanks to its enterprise-grade security (AES‑256 encryption, SIP‑TLS), available up to 99.999% uptime SLA, and local survivability options.

Plus, customers love Zoom. One client said, “I swapped from Mitel to Zoom Phone rather than making the switch to RingCentral, and it was the best decision I’ve ever made.”

Nextiva offers a straightforward VoIP solution with built-in CRM integrations that display caller details, like account history and recent activity, while the phone is ringing. This gives reps the context they need before answering, which helps improve customer interactions.

Admins can set up call routing rules and auto attendants to direct calls to the right person or department based on predefined inputs — no IT team required. The platform also supports business texting (SMS), voicemail-to-email, call recording, and mobile and desktop apps, so it’s easy to stay connected from anywhere.

Microsoft Teams Phone brings calls and text messaging into Microsoft Teams and the wider Microsoft 365 suite. Your team no longer needs to switch between tools to send messages, start video calls, share files, or follow up with customers. 

The Teams environment also offers audio conferencing and AI-powered call summaries, so agents can connect with customers across multiple channels.

Teams Phone is cloud-based, so there’s no need to install a new phone system or buy extra hardware. You can set up features like call groups, call queues, and auto attendants to handle inbound calls more efficiently and route them to the right person.

However, some reviews report that Microsoft Teams Phone is complex to manage, has no unlimited calling option, and costs extra for AI features.

8x8’s native third-party app integrates directly with Salesforce, the world’s most popular CRM system. Sales and support teams can handle calls and messages, view customer history, and log notes without switching between systems.

8x8’s analytics tools help streamline automated workflows (like IVR and call queues). Your team can respond faster to queries, manage higher call volumes, and reduce the time it takes to resolve case issues. The platform also offers a team meeting and messaging service to improve internal collaboration. 

With the 8x8 integration, Salesforce-managed teams can call, message, and hold video meetings without having to switch between tools.

Dialpad Talk (Connect) is a straightforward cloud phone system that supports voice calls, SMS, video, and team chat. It includes auto attendants with smart call routing, unlimited ring groups, and call recording across plans. 

Built‑in AI features like searchable call summaries promote clarity and team efficiency. Plus, integrations with HubSpot, Slack, Zapier, and more mean you can streamline workflows across your core tools.

Google Voice lets users make calls, send texts, and access voicemail directly from Gmail, Google Meet, or Calendar — on desktop, mobile, or desk phones. You can manage number allocation and porting, plus set user access and privileges from the same console you use to control your other Google services. 

You can also route voicemails and SMS messages directly to Gmail based on each user’s working hours for better visibility and faster response times. The system transcribes voicemails and sends them straight to users’ inboxes.

Google Voice includes features that may suit smaller teams, like multi-level auto attendants for routing, ring groups for shared inbound lines, and call forwarding.

Unlike many competitors, Grasshopper charges per company rather than per user. So, you can add team members at no additional cost, aside from usage-based charges like calls or extra numbers. The app supports core calling features, including voice, voicemail, Wi-Fi calling, and SMS across desktop and mobile.

It’s a lightweight, virtual phone system with essentials like custom greetings, call forwarding, incoming call control, and virtual extensions. Users can also set up auto-replies to missed calls and access basic call reports through the dashboard.

While it lacks more advanced VoIP features like integrations or call routing tools, Grasshopper is a budget-friendly choice for small businesses that want a professional presence without a full-fledged phone system.

Ooma supports voice, SMS, MMS, and voicemail-to-email across mobile, desktop, and desk phones, giving companies a broad omnichannel setup straight out of the box.

For inbound call handling, you can set up multi-path IVR receptionists to route calls based on business hours, language preference, or department. 

The platform’s premium plans include advanced features like ring groups, music on hold, paging, intercom, voicemail-to-email, and call flip. It’s a major contrast to companies like RingCentral, which charge extra for these features.

Other useful features include unlimited phone calls to the U.S., Canada, and Mexico, and an auto-dialer for outbound campaigns. Ooma could be a good choice for small companies that want to manage calls, messages, and voicemail from an easy-to-use but limited platform.

GoTo Connect offers a flexible cloud phone system with calling, messaging, and video conferencing. Its basic plan includes free calling to 50+ countries, 1,000 toll-free minutes, call routing tools, SMS/MMS, and video meetings for up to 250 participants. 

The drag-and-drop editor lets your business easily manage auto attendants, dial plans, and call queues while benefiting from SSO, multi-site management, and integrations with Microsoft Teams and Google Workspace.

However, unlike providers like Zoom, GoTo doesn’t offer a bring-your-own-carrier option. While it’s a strong solution for companies looking for global VoIP coverage with built-in messaging and meetings, some IT teams may find it limiting.

Vonage’s basic plan gives you the essentials without any fluff. You get desktop and mobile apps, so you can make and take calls wherever you are. Need calls to reach the right person? Call forwarding and call transfer have you covered. Plus, Vonage Meetings make quick video calls easy, and U.K. landlines or mobiles are just 10 pence per minute.

Other providers, like Zoom Phone, include more advanced features, such as Visual Voicemail, even in its base plans. Zoom Phone is worth considering if you want to step up productivity and make reviewing voicemails as fast and easy as checking your email.

OpenPhone shared SMS inbox simplifies team communication, letting sales and customer service reps collaborate efficiently. Agents can access full client call and message histories, tag teammates, and leave notes right in the conversation thread. 

While you can use it standalone without a CRM, it integrates smoothly with popular tools like Zapier, HubSpot, and Salesforce. AI features like smart call summaries and voicemail transcripts help speed up issue resolution and reduce repeat conversations.

OpenPhone supports SMS and MMS alongside voice calls, and its intuitive dashboard combines call logs, texts, voicemails, and internal notes in one place.
