7 Best Services for VoIP International Calls

Among the VoIP international calling providers here, I find RingCentral the most suitable for companies looking to connect their systems to existing business tools. It integrates seamlessly with over 300 third-party apps, including top CRM platforms such as Salesforce, HubSpot, and Microsoft Dynamics 365. Productivity solutions like Microsoft Teams and Slack are likewise part of the integration gallery.

The VoIP phone system allows custom integrations through APIs, letting you add RingCentral’s calling capabilities to your business platforms. One downside of choosing RingCentral is that a subscription plan upgrade is necessary to unlock internet fax. This feature is available on Ooma’s entry-level plan, which only costs $19.95 per user per month.

All plans include unlimited domestic calling, a call menu, HD video meetings, and an AI assistant. Upgrade to higher plans to access CRM integrations, advanced call monitoring, and customizable analytics. Get started with RingCentral’s 14-day free trial.

• Virtual extensions: Facilitate faster customer service by allowing callers to connect to their desired destination. Assign specific phone lines to different office branches. RingCentral allows up to eight-digit phone extensions.
• Hot desking: Let team members use any phone in your system and have their unique profile settings logged into that device. This is especially useful for employees who travel to and from various company branches.
• Call park: Put a call on hold and place it in a communal parking spot to let colleagues take over and address the customer’s concern. The system sends a notification about a parked call left unanswered for five minutes.

Zoom Phone ranks among the best VoIP for international calls, providing an affordable and organized way to communicate with regional and overseas clients. It’s especially ideal for globally distributed teams since its highest-tier plan (priced at only $20 per user per month) allows unlimited regional calling within one of the 48 countries supported. These include Australia, France, Brazil, South Africa, and Italy.

The platform lets you add $10 monthly for unlimited global calling. With this, you can place as many international voice-over-IP calls as you need to colleagues and customers.

While Zoom Phone users can access post-call summaries, the platform lacks more robust AI capabilities like live coaching and predictive routing. If you need more of these AI-powered functionalities to enhance your communications, consider RingCentral.

All plans offer unlimited domestic calls, metered international calling, HD call quality, 24×7 live chat and phone support, and holiday and business hours routing.

• Call monitoring: Observe live calls between agents and customers. Use the whisper feature to coach agents without the clients knowing. If you need to address the customer directly, select the “Barge” button.
• Elevate to a meeting: Explain matters in depth by converting a phone call to a video meeting. Select the “Meet” button from the in-call control options to start a session.
• Lock and unlock a call: Keep other team members in a shared line group from accessing a live conversation. Use this feature when dealing with a highly confidential customer concern.

GoTo Connect is my top-recommended solution for companies making a high volume of calls across different locations. It boasts a broad global coverage, letting users make free international calls online to over 50 overseas locations, including Australia, Denmark, Greece, Hong Kong, Mexico, and New Zealand.

The software solution, which scales to a full-fledged contact center, has various VoIP features that help manage call traffic. The auto-attendant directs customers to the right agents, while ring groups ensure no calls are missed.

While GoTo Connect offers free international calls across its plans, it doesn’t provide global numbers. If your priority is to set up a virtual presence overseas, 8×8 is the best VoIP solution.

All plans offer Admin GoPilot, an AI-powered assistance for configuring the system. Users also get 24/7 customer support, smart call routing, auto-attendants, and team messaging. Upgrade to higher plans to access AI chat analysis, real-time reports, and intelligent call routing.

• Intelligent call routing: Distribute phone calls to the most skilled agent to address a specific concern. This increases the first contact resolution rate and creates a more positive customer experience.
• Instant response: When you’re not free to take a call, GoTo Connect automatically texts back first-time callers about your availability. This feature lets you engage with customers even when you’re busy and gives them the peace of mind that you received their message.
• Call flip: Switch devices while on an active phone conversation. The call will automatically end on the initial device once you pick it up from the other.

Nextiva should be your top choice if you prioritize unified communications, letting you engage with colleagues and customers on various platforms. Aside from voice, it also supports SMS, virtual fax, team chat, and video conferencing. With Nextiva’s threaded conversations feature, all communications, regardless of the platform used, are kept in one place, helping you refer to specific messages more easily.

However, note that Nextiva charges international calls per minute. If you frequently contact clients overseas, choose other providers like 8×8, which offer unlimited plans to find cheaper ways to call internationally.

All plans include 24/7 customer support, geo-redundancy, and messaging apps. Upgrade to higher plans to unlock video meetings, priority routing, and web chat. Contact Nextiva’s sales team to schedule a demo.

• Call presence: Know the availability status of each team member without directly calling or messaging them. The status options are Online, Busy, Do Not Disturb, Away, and Offline. These can be manually or automatically changed.
• Call transfer: Move a call to a colleague who will expertly answer the customer’s query. Nextiva supports warm transfer, allowing users to inform the receiving agent what the call is about, and blind transfer, moving the call without speaking to the other party.
• Call notify: Get notified by email when a qualified call comes through your line. This is especially beneficial for teams receiving high-volume calls but keen to hear back from a specific caller.

I consider Ooma the best overall VoIP international call provider for homepreneurs with overseas clients, mainly because of its residential phone plan, which has extensive country coverage. The international calling packages, which start at $17.99 a month, enable you to place as many calls as you want to landlines in up to 70 locations. Supported countries include Australia, Denmark, Italy, New Zealand, Sweden, and the U.K.

To access the international calling plan, however, you must purchase the provider’s analog telephone adapter, Ooma Telo, for $99.99. Moreover, the call management capabilities under Ooma’s home phone package are limited. If you receive a large volume of international calls, it’s better to go for business phone systems with robust VoIP features, like Zoom Phone and GoTo Connect.

• Backup number: When the internet connection is down or the power goes out, Ooma automatically forwards calls to an alternate phone number you set. In times of emergencies, your business remains available for customers needing assistance.
• Call forwarding: Redirect calls to another device or phone number and ensure you don’t miss any customer queries. Depending on your configuration, Ooma alerts your device or a colleague’s phone number.
• Expanded call blocking: Choose among various call blocking modes on Ooma Premier: anonymous callers, suspected spammers, or specific contacts.

8×8 is the best VoIP for international calls, allowing businesses to communicate with clients in over 40 countries and secure local phone numbers in over 100 overseas locations. This makes it the ideal software solution for companies wanting to establish a local impression overseas.

The phone numbers offered cover key business regions. For instance, in Asia-Pacific, you can secure numbers in Japan, Thailand, and Singapore. In Europe, you can have a virtual presence in France, Germany, Italy, Norway, and Russia.

The drawback I found in choosing 8×8 is that subscription rates aren’t readily available. Other providers are more transparent with their pricing structure. Zoom Phone is the most affordable in this guide, with a monthly starting price of $10 per user and an international calling add-on fee of $10.

8×8 also offers other communication solutions, namely Contact Center, CX Beyond the Contact Center, Communication APIs, and Unified Communications. However, pricing information for these services is not published online. Schedule a demo or request a quote with its sales team.

• Call queue: Place customers in a virtual line while waiting for an available agent. 8×8’s queues have voicemail boxes, allowing clients to leave a message when they don’t want to wait for a long period in the queue.
• Three-way calling: Hop on a quick huddle with team members or clients through three-way calling. If you need to include more participants, convert the call into a video meeting by clicking the “Meet Now” button in the in-call control menu.
• Conversation IQ: Powered by artificial intelligence (AI), this feature generates trend reports and analysis, giving businesses a peek into customer engagement. As you identify the most common client concerns and sentiments, create better communication strategies that improve customer service quality.

It might be surprising to see Grasshopper in this guide, but do note that this virtual phone system is a game-changer for businesses that don’t need to make frequent international calls. While international and offshore calls are billed per minute, team members can share seats and pay for one account rather than per user — which, ultimately, is a more cost-efficient option.

Aside from simplicity, Grasshopper stands out for offering non-negotiables when it comes to call management: call forwarding, call recording, voicemail, customer greetings, and detailed reporting. However, teams that require more advanced features like AI transcriptions and automations should look at other alternatives like RingCentral.

Grasshopper offers a free trial. All plans include mobile and desktop apps, VoIP/Wi-Fi calling, virtual fax, and reporting. Upgrade to higher plans if you need to facilitate call transfers and simultaneous call handling.

• Mobile and desktop apps: Ideal for global and remote teams, Grasshopper’s apps let teams manage business calls and texts from anywhere, through an internet connection.
• Business texting: Lets users send and receive unlimited text messages to customers and clients, enabling them to separate personal and business phone numbers.
• Simultaneous call handling: Grasshopper forwards calls to different extensions, allowing teams to take multiple incoming calls.
