RingCentral Office Phone

The phone system includes a local or toll-free virtual number, and RingCentral offers local phone numbers around the world and the option to port in your pre-existing numbers. RingCentral plans support unlimited calling within the US.

Who is RingCentral Best For?

RingCentral is ideal for American companies looking for a phone system with integrated collaboration features. Despite its offering of advanced collaboration tools like file sharing and whiteboards, RingCentral does not provide unrestricted international calling beyond North America, unlike some of its competitors.

Why We Picked Them

We chose RingCentral for its robust collaboration features and multiple communication channels, all integrated within a user-friendly business communications application.

  • Call queueing and analytics: Organize agents into queue groups, with live queue statistics such as average wait time and the number of online agents

Who is Ooma Best For?

Ooma is best for companies seeking phone and SMS only, especially those that call mostly within the US, Canada, and Mexico. Ooma video conferencing lacks collaboration features, and they don’t offer team chat.

Why We Picked Them

Ooma provides high-definition voice calling quality globally, with an extensive unlimited calling network covering 3 countries. In addition, its phone system features a comprehensive set of basic functions, including multichannel and collaboration capabilities.

Dialpad

Who is Dialpad Best For?

Dialpad is best for small US-based companies prioritizing team collaboration and AI-enhanced agent support. While Dialpad’s unlimited-calling area is smaller than alternatives, and its video meetings support far fewer participants than average, the platform uniquely offers live speech transcription and AI coaching.

Why We Picked Them

Dialpap’s automated and AI offerings provide unique features that no alternative phone system can match.

8×8

The X Series from 8×8 is a UCaaS platform and business phone system that supports various communication channels such as VoIP calling, team chat, SMS texting, and video conferencing.

  • Call monitoring: Supervisors can listen in on conversations, “whisper” private guidance to on-call agents, “barge” into the call to participate, or take over the call completely
  • Multi-level auto attendant

Who is 8×8 Best For?

For companies with a significant amount of international calling, 8×8’s X2 and X4 plans are well-suited, as they offer free calling to 14 and 48 countries, respectively. The choice between the two plans depends on the specific countries that a company calls most frequently, as these countries may fall under either the X2’s 14-country free-calling area or the X4’s 48-country free-calling area.

Why We Picked Them

When it comes to international VoIP solutions, 8×8 offers everything a company needs: multiple communication channels, internal collaboration options, analytics, routing, and a wide international domain for unlimited calling.

Who is Vonage Best For?

Why We Picked Them

Vonage’s global calling plans offer unique flexibility for companies with small-but-consistent international calling needs. They offer the best per-minute international calling rates on our list.

Grasshopper

Grasshopper is a phone system that operates in the cloud and offers VoIP calling and SMS texting capabilities. Its features include basic call management tools such as call forwarding, voicemail transcription, call transfers, custom greetings, and immediate text responses.

Grasshopper app

Additionally, it offers local, toll-free, and vanity phone numbers in area codes throughout the US, and allows customers to transfer their existing phone numbers to the platform.

Pricing

Grasshopper’s pricing structure is unique in that each plan is charged by the account–rather than by the user–and each account includes a bundle of phone numbers and extensions.

Business Phone System PlansUnlimited Calling AreaInternational Calls (per minute)
Solo: $26 monthly for 1 phone number and 3 extensions Partner: $44 monthly for 3 phone numbers and 6 extensions Small Business: $80 monthly for 5 phone numbers and unlimited extensionsUS and Canada$0.02 to China $0.04 to UK $0.43 to India $0.10 to Australia Up to $0.95 elsewhere

  • Custom Greetings: Record custom greetings and announcements, which play for inbound callers who reach a particular number
  • Automated SMS instant response

Who is Grasshopper Best For?

For small businesses based in the US seeking a straightforward phone system, Grasshopper is a suitable option. Their pricing structure offers budget-friendly deals for companies that plan to share five or fewer phone numbers among 6-20 users. However, some users may be disappointed with the platform’s lack of key routing features and communication channels, such as IVR and team chat.

Why We Picked Them

We chose Grasshopper for their user-friendly virtual phone system, basic phone features, and small-business-friendly pricing structures, potentially costing under $10 per user per month. Nonetheless, companies that make frequent international calls should consider other options as Grasshopper’s unlimited calling area is limited.

How to Make International Calls with VoIP

To call a landline, mobile phone, or VoIP number internationally, use the following process:

1. Dial your country’s exit code: In the US and Canada, this is + (plus sign) or 011. Most other countries use 00 as the exit code

2. Dial the destination’s country code: If calling a US or Canada number, the country code is 1. Other countries have their own code, listed here.

3. Dial the recipient’s area code: Part of the phone’s 10-digit number, the area code changes by city or region

4. Dial the recipient’s 7-digit number

Example CallExit CodeCountry CodeArea Code7-Digit Number
US to London, UK011 (US)00 (United Kingdom)020 (London)315-8783

How to Choose a Provider for International VoIP Calls

The best provider for international VoIP calls depends on your company’s business needs. Some of the providers listed above emphasize collaborative UCaaS features like video-conferencing, file-sharing, and team chat, while others emphasize routing features or a wide unlimited calling area.

When picking a provider, consider the following:

  • Unlimited calling area: Some providers only offer unlimited calling within the United States and Canada. Some include Mexico, while some offer international calling options in over 50 countries. Consider where you call, and how often, to evaluate how large of an unlimited area you need.
  • Phone number offerings: Some of the above providers only offer business phone numbers from area codes within the US, while some provide international numbers. If you want to establish an overseas presence, consider a provider that offers virtual phone numbers in your desired country.
  • Routing and queuing features: Some of the providers listed above offer diverse routing and queueing features–IVR, hold queues, ring groups, and custom ring styles–that transform your phone system into a call center. Alternatively, some providers don’t offer any of these features. Consider your inbound call volume to determine if you want advanced routing features.
  • Channel offerings: Consider your team’s internal collaboration needs to decide if you want a phone system that offers team chat and video conferencing. Even further, determine if you want to prioritize advanced collaborative features, like whiteboards and file sharing.
