What is the difference between international numbers, international minutes, and international calling plans?

International numbers, international minutes, and international calling plans are three separate purchases on a business phone system. A provider can be strong on one and weak on another, so each needs its own check before signing.

• International numbers: local, mobile, or toll-free numbers registered in another country. Customers there see a familiar caller ID and pay local rates to call back. A number on its own includes no outbound minutes.
• International minutes: outbound calls to another country, priced by destination and by line type. Calls to mobiles cost several times more than calls to landlines: €0.307 against €0.050 per minute to Germany on CloudTalk’s pay-as-you-go rates.
• International calling plans: monthly packages that turn per-minute charges into a fixed fee. Most exclude toll-free, premium-rate, and forwarded calls, and most carry a fair-use cap, such as 3,000 minutes per user per month.

What do you need to get a business phone number in another country?

A business phone number in another country usually requires proof of a local address and proof that the business exists. Each country’s telecom regulator sets the rules, and Germany is a typical example:

• Local (geographic) numbers: a German address that matches the area code, proof of entity, and proof of address such as a utility bill no older than 3 months.
• Mobile numbers: a German address anywhere in the country, plus a company website and a named company representative.
• Toll-free numbers: an allocation letter issued by the Federal Network Agency (BNetzA) for the specific number.

US and Canada numbers activate instantly on CloudTalk with no documents. Numbers in countries with document checks take 4 to 5 business days to approve after the documents are uploaded.

How much does international calling cost a sales team?

International calling for a 20-rep sales team costs from about $500 to over €3,000 a month, and the share of calls going to mobiles moves the bill more than the choice of provider. The example assumes each rep calls Germany for 500 minutes a month, 10,000 minutes in total:

Pricing model	Rate	Monthly cost for 10,000 minutes
Pay-as-you-go, German landlines	€0.050/min	€500
Pay-as-you-go, German mobiles	€0.307/min	€3,070
Prepaid minute bundle	about $0.05/min	about $500
Per-seat regional bundle	up to $25/seat	up to $500

The same 10,000 minutes cost 6 times more to mobiles than to landlines on per-minute rates. Teams that mostly reach prospects on mobile numbers save the most by moving to a bundle or an unlimited zone.

Three costs sit outside the per-minute rate:

• Extra numbers: $5 to $6 per number per month on Zoom Phone and Aircall.
• Fair-use caps: “unlimited” plans stop at a fixed number of minutes per user, such as 3,000 a month.
• Unused bundle minutes: prepaid minutes on plans such as Vonage Global Calling Plans do not roll over.

What rules apply to sales calls into Germany, France, and Spain?

Sales calls to consumers in Germany, France, and Spain need prior consent, and Germany also restricts cold calls to businesses. Each country sets its own penalties:

• Germany: calls to consumers need prior express consent, and calls to businesses need at least presumed consent, meaning concrete signs of interest in the offer. Consent must be documented and kept for 5 years. Fines reach €300,000 for calling without consent and €50,000 for missing records.
• France: since August 2026, businesses cannot make marketing calls to consumers without prior consent, replacing the Bloctel opt-out list. Fines reach €75,000 per call for the caller and €375,000 for the company that ordered the calls.
• Spain: since June 30, 2023, Article 66 of the General Telecommunications Law allows commercial calls to consumers only with prior, express consent.

A phone system connected to the CRM keeps the call log and the consent record on the same contact, which is the record German regulators can ask to see. Rules change often, so confirm current requirements with local counsel before a campaign.

Conclusion: choosing the best business phone system for international calling

The best business phone system for international calling is the one that covers the countries a team calls, at a price that fits how often it calls them. CloudTalk ranks first with a score of 9.1/10, on local numbers in 160+ countries, published bundles from $5 per seat, and dialers built for SMB sales and support teams.

The other nine providers each lead on a narrower need:

• Fixed set of countries, called daily: 8×8, with unlimited calling to 48 countries on X4 and higher tiers.
• One unlimited worldwide contract: Aircall Enterprise.
• Staff on payroll in many countries: RingCentral Global RingEX, with native service in 45 countries.
• International spend capped in advance: Vonage Global Calling Plans, from $50 per 1,000 minutes.
• In-region audio quality: Dialpad, on its own voice network in 50+ countries.
• A Zoom or Microsoft 365 stack: Zoom Phone Global Select or Microsoft Teams Phone.
• Occasional calls abroad: GoTo Connect, with free calls to 48 destinations, or Nextiva, with per-minute rates from about $0.01.

Three checks decide the final choice for any team: whether local numbers exist in every target country, whether most calls go to mobiles or landlines, and whether consent rules in markets such as Germany, France, and Spain shape how the team is allowed to call.

FAQs

Is VoIP cheaper than traditional international calling?

VoIP is usually cheaper than traditional international calling because the call travels over the internet and only joins the phone network near the destination. Calls between users on the same VoIP system cost nothing at all, wherever they sit: Dialpad, for example, does not charge for Dialpad-to-Dialpad calls.

Can I keep my existing business number when switching providers?

You can keep an existing business number when switching providers by porting it to the new one. In the US, the FCC requires simple ports to finish within one business day, though multi-line business ports usually take longer. Ports of numbers in other countries follow each country’s regulator and often need the same documents as a new number.

What has replaced Skype for international business calls?

Microsoft Teams replaced Skype after Microsoft retired Skype in May 2025. Businesses that called abroad on Skype now typically use Microsoft Teams Phone, with its $34 domestic and international calling plan, or a cloud phone system such as CloudTalk, RingCentral, or Zoom Phone that sells international numbers and minute bundles.

Is call recording legal on international business calls?

Call recording on international business calls is legal in most countries when every party is told about it and the business has a lawful basis. In the US, states such as California, Florida, Illinois, Pennsylvania, and Washington require consent from all parties. Under GDPR, businesses must tell EU callers that the call is recorded and why.

Is VoIP call quality good enough for international business calls?

VoIP call quality is good enough for international business calls when the connection stays within three limits: under 150 ms of one-way latency, under 30 ms of jitter, and under 1% packet loss. Calls start to sound awkward above 150 ms of latency and break down above 300 ms, so long routes benefit from providers that route calls inside the destination region.

Can I use my business number while traveling abroad?

You can use a business number while traveling abroad by calling from the provider’s mobile or desktop app over Wi-Fi or mobile data. Outbound calls still show the business caller ID, and most VoIP providers price the call by its destination, not by where the caller is sitting.
