RingCentral: Best for Unified Communications
*Save up to 33% by paying annually. Volume discounts for 50-plus users are available.
RingCentral is the best VoIP app for companies aiming to keep key communication channels in one place. It offers tools for managing phone calls, text messages, team chats, and video meetings, eliminating the need for separate communication platforms and the likelihood of data silos.
The VoIP phone system handles large volumes of calls, thanks to the robust call management tools, which include the interactive voice response (IVR) system, call forwarding, extensions, and call delegation. Professionals who frequently travel are able to stay connected through hot desking and shared lines. As for team collaboration tools, RingCentral supports file sharing and task management in instant messaging and artificial intelligence (AI) insights in video meetings.
Unfortunately, RingCentral only allows a maximum of 200 text credits per user a month. Other VoIP apps like Vonage enable users to send unlimited SMS to colleagues and customers.
- Presence: See who among your colleagues is available for a phone call or a meeting. Team members’ user presence may be set to available, busy, or do not disturb modes.
- Hot desking: Allow team members to log into any phone in your system and access their unique extensions, profiles, or voicemail inboxes. With this, anyone can work anywhere in the office and freely collaborate with other departments without missing important calls.
- Call delegation: Assign assistants to answer incoming calls for executives. RingCentral allows a maximum of 10 assistants to an executive and 10 executives to an assistant.
Nextiva: Best for Long-distance Calls
*Pay $23.95, $27.95, and $37.95 for the tiered subscriptions when you choose annual billing. Volume discounts are available for more than four users.
Nextiva is our top-recommended VoIP app for growing businesses receiving calls from a national client base, as it offers a toll-free minute allowance in its subscription plans. The most expensive plan has 12,500 minutes, which can accommodate high-volume calls of non-technical customer queries.
The best part about Nextiva is its built-in ticket management feature, which allows you to assign requests to team members and makes resolving concerns more efficient. While Nextiva is the ideal VoIP phone app for long-distance calls, it keeps its voicemail transcription—a key phone feature—in its most expensive plan. If you don’t want to pay more for this tool, go for Grasshopper, which offers transcription in its base-level plan costing $17 per user, monthly.
- Call pop: Refer to key customer details while on a live call. Call pop displays customer sentiment from the caller’s last interaction with your business, last survey response, experience score, and the value of their account.
- Call pulling: If you’re in an ongoing call and need to step away from your desk, use call pulling to move a call from your desktop phone to your mobile. With this, you don’t need to cut the conversation short and interrupt the flow of the discussion.
- Threaded conversations: View past calls, voicemail messages, chats, and texts in one place. This eliminates the need to switch between menu tabs to find messages.
Vonage: Best for Customized Call Flows
*Volume discounts are available for more than four users.
Vonage is the best VoIP app for businesses looking to customize call flows and personalize customer interactions. It features smart numbers, a tool that uses various application programming interfaces (APIs) to perform different functions programmatically. You may program the system to send the agent’s schedule availability, broadcast a voice alert, prompt a two-factor authentication, or send a text when a customer reaches your number.
Aside from customizing call flows, Vonage lets businesses modify the actual phone system depending on their needs. It offers more than 40 default unified communications (UC) features and a separate menu of add-on tools to manage calls more efficiently. Unfortunately, some of these add-ons are expensive. For instance, call queues cost $250 per queue, monthly, for unlimited use.
Consider the other best VoIP apps listed here if you consistently receive large volumes of calls. Call queues are readily available in RingCentral’s entry-level plan costing $30 per user, monthly. Meanwhile, Dialpad’s hold queues are in its second-tier plan priced at $35 per user, per month.
- Virtual receptionist: Let an auto-attendant answer incoming calls and distribute them to appropriate departments or team members. Configure the phone menu in a way that reflects common customer concerns.
- Caller ID block: Keep your business name and phone number private when placing calls. Call recipients will see “Unavailable” or “Blocked” when they see the incoming call alert.
- Call tagging: Add labels to calls to quickly organize customer conversations later. This is especially useful for marketing campaigns, as it helps you evaluate success by looking at the volume of calls representing interest in products or services.
Dialpad: Best for Artificial Intelligence
*Pay only $15 and $25 for the Standard and Pro plans, respectively, when you choose annual billing.
Dialpad is the best app for VoIP call center teams wanting to boost agent efficiency through artificial intelligence (AI). Through natural language processing, the Action Items feature automatically detects different types of action steps mentioned in calls and meetings, including contacting an individual, sharing information, or scheduling a meeting.
With this, service representatives don’t have to spend a significant amount of time going over phone calls and extracting the next action steps. They immediately get to doing the required to-do’s. When you upgrade to Dialpad’s contact center plans, Custom Moments helps you monitor specific topics during a call. When a predefined phrase is mentioned in a conversation, the system automatically files that under Custom Moments, making referring to that specific topic easier later.
While Dialpad is an excellent, AI-powered solution, it’s not the best meeting platform, as it only allows up to 10 participants in a session. It limits meetings to five hours. RingCentral is the ideal VoIP solution for companies wanting to host big groups of attendees and long discussions, as it supports 500 participants and a 24-hour duration.
- Customizable caller ID: Switch between different phone numbers to reflect your main company’s phone number or your specific department’s. With this, you’ll maintain professionalism in your communications and increase call connection rates, as recipients instantly know who’s calling them.
- Call park: If you want other team members to access a live call and take over customer concerns, place the caller on hold and put it in a communal parking spot. Park your most valuable clients in VIP parking spaces so team members can prioritize them when retrieving calls.
- Three-way calling: Customer service representatives have the option to add managers or seasoned agents to an existing call to quickly address a complex concern. Click the person with the plus sign icon on the call control buttons to begin a three-way call.
Grasshopper: Best for VoIP Beginners
*Save over 10% by paying annually. All subscription plans include all VoIP features, including call forwarding, simultaneous call handling, and virtual fax.
Grasshopper is the best VoIP app for small businesses new to cloud-based phone systems because it’s a lightweight platform. Its bare-bones features and simple interface are not intimidating for beginners and won’t require long hours of technical training. In fact, you may be familiar with the platform within a few minutes. Moreover, it’s easy to set up the VoIP system.
What’s better about Grasshopper is its affordability. While other VoIP providers charge per user, Grasshopper has a flat rate pricing for unlimited users starting in the Solo Plus plan. As you grow your company, you don’t need to pay more for extra seats for additional team members.
However, this VoIP provider may not be the best solution for your business if you’re looking for advanced call management tools that would help you manage large amounts of customer inquiries. It lacks a call flow editor, skills-based routing, call monitoring, and call recording. If you’re dealing with high call volumes, RingCentral is the better choice given its advanced VoIP tools.
- Business hours: Set up a schedule for each extension based on your team’s operating hours. You only get calls when you want them or are available to take them.
- Toll-free numbers: Encourage your customers to call you using toll-free numbers so they won’t incur calling charges. Toll-free numbers present a professional image and allow you to be available to your nationwide clientele.
- Voice Studio: Grasshopper has a pool of professional voice actors who can record your custom phone greetings. Announcements can be recorded in English and Spanish.
Ooma: Best for Home-based Freelancers
Ooma is the suitable VoIP software solution for home-based solopreneurs, as it provides a residential plan free of monthly charge. Purchase the VoIP phone adapter Telo for a one-time fee of $99.99 and you’ll access essential phone capabilities, such as domestic calling, high-definition voice, call logs, and answering machine, without the worry and hassle of monthly fees. Given this subscription plan offering, Ooma makes for the best free VoIP app.
As you grow your operations and require more advanced VoIP tools, upgrade to Ooma Office, which starts at an affordable price of $19.95 per user, monthly. The higher-tier subscription plans offer team chat and video conferencing on top of the call management features.
Unlike other VoIP providers, Ooma doesn’t offer international numbers. In contrast, RingCentral has local phone numbers in over 100 countries. Phone.com covers 50-plus countries and provides discounts for bulk purchases.
- Simultaneous ring: Minimize customer wait times or missed calls by alerting multiple devices simultaneously. When an incoming call is received, all the devices—IP phones, mobile phones, and applications—connected to the extension will ring.
- Shared voicemail boxes: Users sharing extensions like ring groups have a dedicated voicemail box accessible to all team members. This allows team members to respond faster and refer to messages easily.
- Call blocking: Prevent telemarketers from reaching your business phone line. Ooma allows you to configure robocall blocking actions, with options to play a busy tone or send to voicemail.
Phone.com: Best for Fluctuating Call Volumes
*Save 15% by paying annually. Volume discounts are available for more than four users.
Phone.com is the best VoIP solution for companies dealing with fluctuating call volumes, as it has metered and unlimited calling plans. The entry-level plan includes 500 pooled minutes, ideal for those times you have low call volumes. Each user on the account adds 500 minutes usable for both inbound and outbound calls. If you have five users in an account, those users have access to 2,500 minutes.
Meanwhile, Phone.com’s two higher-tier plans have unlimited minutes, which suit those times when you receive a huge volume of customer queries. But regardless of the subscription package you choose, you’ll have access to almost all the VoIP features Phone.com offers, including call forwarding, call waiting, call screening, and follow me.
Besides that, Phone.com is one of the best VoIP apps for international calls. Take advantage of the low per-minute rates and the local fees on calls to landline numbers in Canada, France, Germany, Israel, Italy, Puerto Rico, and the United Kingdom.
However, note that when you choose this VoIP provider, you can only integrate it with four third-party apps. If you don’t want to use an integration platform like Zapier to link external solutions, go for a platform with robust prebuilt integrations like RingCentral, which connects to over 300 apps.
- Call handling: Set rules and protocols for routing incoming calls. Determine whether calls should be routed to a single or different destination depending on the time of day or caller.
- Voicemail transcription: The phone system automatically converts voicemail messages to readable text and sends the written version to your email or as a text message. Go through your messages without listening to the audio clips. Forward transcriptions to others for documentation.
- Greetings: Personalize your audio greetings, music, menus, and messages by uploading audio files. Phone.com supports different file formats, such as MP3, GSM, and WAV.
