Zoom Phone: Best for Reducing Globally Distributed Teams’ Call Costs
Zoom Phone is our overall best solution for VoIP international calls—ideal for companies with multiple offices overseas, as it provides robust domestic and global calling support at an affordable price. Its Select plan allows businesses outside the U.S. to pay $20 per user for unlimited calls within a specific territory.
The countries where Zoom Phone offers local Public Switched Telephone Network (PSTN) services include Australia, New Zealand, Japan, Mexico, and Germany. For offices placing frequent calls outside their location, the Select plan offers an international calling add-on, which comes with unlimited calls to 19 countries for only $10 a month. Regardless of your package, you’ll access almost all the VoIP features Zoom offers.
While this provider is an excellent option for companies managing communication costs for several offices overseas, its country coverage for unlimited calls is not as robust as other providers. It’s limited to only 19 overseas locations. The best VoIP for international calls to multiple countries is GoTo Connect, allowing businesses to place unlimited calls to 50-plus territories.
Zoom Phone Features
- Call monitoring: Observe live calls between agents and customers. Use the whisper feature to coach service representatives without the clients knowing. If you need to directly address the customer, select the barge button.
- Elevate to meeting: Provide a more detailed explanation when addressing a customer query 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 you’re dealing with a highly confidential customer concern.

RingCentral: Best for Securing Hardware Devices for International Companies
*Save up to 33% with annual billing; volume discounts are available for 50-plus users.
RingCentral is among the best solutions for VoIP international calls, as it provides an extensive list of hardware devices for global teams. The supported phones include popular brands companies use: Poly, Cisco, Yealink, Avaya, Mitel, and Unify. The business phone system provider oversees the local shipment of phones with region-compliant power supplies.
On top of this, RingCentral Global MVP offers public switched telephone network (PSTN) services in over 45 countries, helping companies strengthen their local presence overseas. Access 1,000 minutes of monthly regional calling per user. Through global Quality of Service reports, identify call quality problems in different countries or regions.
Before subscribing to RingCentral for managing VoIP international calls, note that its internet fax feature isn’t available in the entry-level plan, which already costs $30 per user. If you don’t want to pay more for this service, consider Ooma Office, as its $19.99 subscription package covers virtual fax.
- Virtual extensions: Facilitate faster customer service by allowing callers to connect to the person or department they need. Assign specific phone lines to different business locations. 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.

8×8: Best for Establishing a Virtual Presence in Various Overseas Locations
*Save up to 23% with annual billing. The provider allows businesses to mix and match plans.
8×8 is the best international VoIP platform for companies wanting to establish a presence in different overseas locations, as it provides local phone numbers in over a hundred countries. Its coverage includes key regional markets, namely Asia Pacific, Europe, the Middle East, Africa, and North and Latin America. An international number helps businesses build a local presence while letting customers pay local rates instead of sky-high fees when calling the company.
Complementing the robust international phone number support, unlimited overseas calls to select countries are part of 8×8’s subscription plans. The most expensive package covers 48 territories, which include Australia, Brazil, Greece, Mexico, Norway, and Russia.
One disadvantage of using 8×8 is that it keeps call recordings for 30 days only when you choose the entry-level plan. Meanwhile, the international calling VoIP platform Zoom Phone offers the option of setting the retention period to unlimited, even in its base-level subscription package.
- Call queue: Put customers in a virtual line as they wait for an available agent. 8×8’s queues have voicemail boxes, giving clients the option 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.

For only $17.99, connect with clients in 60-plus countries via landline. These locations include Australia, Bahrain, Denmark, Hong Kong, Singapore, and Switzerland.

The device connects to the modem or router via the Ethernet cable and to the landline phone via the FXS port, allowing traditional phones to place and receive calls over the internet.
Unfortunately, Ooma doesn’t offer global phone number support. Explore other VoIP for international calls if you need to establish a local presence overseas. 8×8 supports local numbers in over a hundred countries.
- 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. Ooma alerts the ATA device Telo, your mobile app, or a colleague’s phone number, depending on your configuration.

Refer to our Ooma review if you’re interested in its business phone system plans. The platform benefits those looking for an affordable VoIP solution.
GoTo Connect: Best for Calling Multiple Clients Overseas
*Save up to 11% with annual billing.
GoTo Connect is the best international VoIP calls platform when you frequently call several clients from different parts of the world. It has the most countries included in its unlimited global calling feature—a total of 52. The locations include Australia, China, France, Germany, Italy, Portugal, Sweden, and the United Kingdom.
While supporting large volumes of outbound international calls, the provider has robust VoIP features for efficient inbound call management, including unlimited, customizable dial plans, ring groups, and call queues. It has unlimited phone extensions, letting you assign as many phone numbers as possible to different teams or agents.
GoTo Connect also caters to companies with low international call volumes, offering a metered option in its base-level plan. The VoIP international rates depend on the destination country. Unfortunately, the package doesn’t include call recording. You must upgrade to the $32 plan to access the feature. In contrast, our best overall international VoIP calls provider, Zoom Phone, has this capability in its base-level subscription package, which costs just $10.
GoTo Connect Features
- Intelligent call routing: Distribute phone calls to the most skilled agent to answer a particular customer concern. This helps increase 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 customers 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.

Phone.com: Best for Expanding Global Presence on a Budget
*Save 15% with annual billing. Volume discounts are available for five or more users.
For companies wanting to establish an international presence without breaking the bank, Phone.com is the most suitable VoIP provider, as it offers U.S. local rates for global numbers. The countries covered are France, Germany, Israel, and the United Kingdom. Pay only $5 a month for numbers in “standard rate countries,” which include Austria, Belgium, Finland, and Sweden. On top of the affordable rates, you’ll get huge discounts as you buy multiple numbers.
When you purchase over 50 phone numbers, the cost is reduced to $2.99. The price is further lowered to $1.99 as you buy 100-plus numbers. Multiple numbers help provide unique phone lines to key employees and accommodate simultaneous customer service calls.
Unfortunately, the provider has limited native third-party integrations. If you plan to connect your phone system to other apps, you’ll likely find those platforms in RingCentral’s marketplace, which hosts over 300 business tools.
- Schedules: Distribute inbound calls to specific phone numbers, extensions, or auto-attendant menus based on the day and time the call went through your system. For instance, when customers call beyond your operating hours, direct them to a greeting that reminds them of your schedule.
- Voice tagging: Know which auto-attendant menu option callers chose before speaking to them. The voice tag helps you align your spiels to the reason the customer called your business.
- Voicemail transcription: Read the text format of voicemails to understand immediately the gist of customer concerns. Even without playing and replaying the audio file, you’ll know which messages to prioritize.
In our Phone.com review, we recommended Phone.com to businesses engaged in marketing campaign tracking because it offers volume discounts on phone numbers. Learn more about the platform in the guide.
Nextiva: Best for US-based Teams Managing Low International Call Volumes
*Save up to 22% with annual billing. Volume discounts are available for five or more users.
Offering low per-minute charges, Nextiva is the best VoIP international calling provider for U.S.-based teams that need to connect with overseas clients occasionally. For instance, calls to Australia only cost 3 cents per minute, compared to Zoom Phone’s 4.4 cents. The difference may seem small, but it translates to huge savings if you’re dealing with multiple calls. Learn how much global calling costs for specific calling minutes by using our Fit International Calculator.
Aside from affordable international calling rates, Nextiva has a generous toll-free minute allowance. The maximum offered at the most expensive subscription plan is 12,500 toll-free minutes. This is beneficial if you’re serving a national customer base and managing high-call volumes every month.
One downside of choosing Nextiva as your VoIP provider for international calling is that you must upgrade to the highest-tier subscription package to unlock voicemail transcription, a standard feature in most business phone systems. The plan comes with custom pricing. In contrast, this tool is available on Zoom Phone’s base-level plan for only $10.
- 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 receiving customer service representative.
- Call notify: Get notified by email when a qualified call comes through your phone system. This is especially beneficial for teams receiving high-volume calls but keen to hear back from a specific caller.
