International calling add-on: Starts at $10 a month for unlimited global calling to 19 countries, including the UK, Ireland, Australia, New Zealand, and Austria
Zoom Phone is our overall best VoIP service for international calls due to its global telephony service that works for businesses with one or multiple offices overseas. Monthly plans are all-inclusive so you don’t have to upgrade to unlock a specific feature. All you need to do is pick your desired call plan—metered local calling, unlimited regional calling, or unlimited calls within a specific territory.
Aside from the U.S. and Canada, Zoom Phone offers local phone services in Australia, New Zealand, Japan, Mexico, and Germany. For offices placing frequent calls outside their location, the Select plan has an international calling add-on, which comes with unlimited calls to 19 countries for only $10 a month.
Unfortunately, Zoom Phone’s country coverage for unlimited calls is not as robust as that of other providers, and it’s limited to 19 overseas locations only. If you’re looking for more extensive international call support, consider GoTo Connect, which allows unlimited calls to over 50 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 address the customer directly, 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 is among the best solutions for VoIP international calling with public switched telephone network (PSTN) services for up to 46 countries. If you have a globally distributed team, RingCentral provides a single phone system that works across multiple devices, including 1,000 minutes of monthly regional calling per user.
On top of this, RingCentral has an extensive list of hardware devices for global teams. The supported phones include popular brands: Poly, Cisco, Yealink, Avaya, Mitel, and Unify. This VoIP phone system provider oversees the local shipment of phones with region-compliant power supplies.
Before subscribing to RingCentral for managing international VoIP 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.
RingCentral Features

- 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.

Ooma supports VoIP international calling for home-based solopreneurs or freelancers communicating regularly with clients overseas. It has a free home phone plan with basic VoIP capabilities that allow unlimited calls to landlines and mobile phones in select countries. Simply add $17.99 to your plan to connect with clients in 60-plus countries via landline. These locations include Australia, Bahrain, Denmark, Hong Kong, Singapore, and Switzerland, to name a few.
When you upgrade to the $25.99 plan, you get free VoIP international calls to 70-plus countries. Ooma lets users send and receive VoIP calls via existing landline systems through its ATA Ooma Telo White. 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. Consider other VoIP providers like 8×8 that support local numbers in over a hundred countries.
Ooma Features
- 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.
- Expanded call blocking: Choose among various call blocking modes on Ooma Premier: anonymous callers, suspected spammers, or specific contacts.
8×8: Best for Global Phone Number Support
What We Like
- PSTN services in over 55 countries

- X4: Custom pricing for unlimited voice calling to 48 countries, 8×8 Frontdesk, call monitoring, and supervisor analytics
8×8 is the best VoIP service for international calls for companies wanting to establish a local presence in different overseas locations. It offers phone number support in over 100 countries and includes key regional markets like Asia Pacific, Europe, the Middle East, Africa, and North and Latin America.
An international number helps businesses reach their global market while letting customers pay local rates instead of sky-high international call fees when calling the company. Complementing the robust international phone number support, unlimited overseas calls to 48 countries are part of 8×8 monthly plans.
One disadvantage of 8×8 is that it keeps call recordings for only 30 days when you choose the entry-level plan. Meanwhile, Zoom Phone offers the option of setting the retention period to unlimited, even in its base-level subscription package.
8×8 Features
- 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.

GoTo Connect is the best international VoIP calls platform when you frequently call several clients from different parts of the world. It has the largest number of 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 has a metered calling option in its base-level plan, where call rates depend on the destination country. Unfortunately, the package doesn’t include call recording—you need to upgrade to the $32 plan to unlock the feature. In contrast, Zoom Phone has this capability in its base plans, which costs $10 only.
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 the peace of mind that you received their message.

- Low rates for international phone numbers ($5 a month)
Where It Falls Behind

Offering low per-minute charges, Nextiva is the best VoIP international calling provider for U.S.-based teams needing to connect with overseas clients occasionally. For instance, calls to Australia only cost three 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.
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 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.
Nextiva Features
- 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.

Frequently Asked Questions (FAQs)
Some countries, including Belize, China, Israel, Jordan, Kuwait, North Korea, Oman, Pakistan, and Qatar, restrict VoIP services. Governments impose bans to protect telecommunication companies’ economic interests or to prevent security risks associated with VoIP.
No. When you’re within the U.S., international calls on Google Voice are charged per minute. If you’re outside the country, the call will consume the minutes in your mobile plan, and extra roaming fees will apply.
VoIP providers like Ooma allow you to call people overseas at no cost as long as the recipient uses the same VoIP app and Ooma Telo base station. Instant messaging apps linked to a phone number, such as WhatsApp and Telegram, operate similarly, enabling free international calls between app users.
Bottom Line
VoIP solutions offering international calling let businesses build rapport with customers abroad and establish a strong global presence. Many come with advanced routing and queueing capabilities, which help streamline call management and facilitate distributed workload among agents. However, each provider has unique offerings, making them ideal for certain use cases.
