3CTel International Calling & Global Numbers lets a Canadian business call the United States and international destinations from its business phone system, hold local numbers in other countries where available, and control which destinations each user can dial. Rates are quoted per destination, caller ID abroad is confirmed for each market, and spending limits and alerts guard against toll fraud.
What changes for your business.
Customers abroad reach you on a local number
An international number, where available, gives a market abroad a familiar number to dial, routed to your Canadian team.
No surprise bill from a destination nobody meant to call
Destinations are allowed per user or group, and premium and high-risk destinations are blocked by default unless you open them.
Staff overseas work as if they were in the office
An employee working from abroad uses the 3CTel app on a laptop or cell phone with their Canadian extension, caller ID and voicemail.
Core capabilities.
Calling to the US and worldwide
Outbound calling to the United States and international destinations from any 3CTel extension. Rates are quoted per destination as part of your plan.
International numbers where available
Local or toll-free numbers in other countries, where a number is available for that country and your business can meet its address or documentation requirements. Availability is confirmed during planning.
Caller ID presentation abroad
Outbound calls present your Canadian business number or, where a number is held there, a local number for the destination. How caller ID is shown depends on the destination network and is confirmed with you.
Dialing rules and destination restrictions
Allowed destinations are set per user, group or site. Premium-rate and high-fraud destinations are blocked by default and opened only on request.
Fraud controls
Spending thresholds, out-of-hours dialing limits and alerts on unusual international volume are configured with you, so a compromised credential cannot run up a bill overnight.
Remote staff abroad on the apps
Employees outside Canada use the desktop and mobile apps with their Canadian extension over an internet connection, keeping calls inside the business system.
International call reporting
International minutes and destinations by user, group and site, so you know who calls where and can adjust rules or plans accordingly.
Time-zone aware routing
Calls to an international number can follow business hours in that market, routing to the right team or to voicemail with a local-language greeting outside hours.
Common use cases.
Canadian exporter with US customers
Sales and support call US accounts from their extensions and, where available, hold a US number that customers dial without thinking about the border.
Immigration or relocation firm
Staff call clients and institutions overseas throughout the day; destination rules keep calls to the countries the firm serves and reporting shows minutes per case.
Company with a developer or support team abroad
Team members in another country run the 3CTel app with a Canadian extension, so internal transfers and customer calls stay in one system.
Tourism operator with markets overseas
A number in a key market abroad, where available, rings a bilingual team in Canada during that market’s business hours and takes a voicemail outside them.
AI voice agent for reminders across time zones
An outbound AI voice agent places appointment reminders and status updates to customers abroad during their business hours under destination rules you approve, and an AI workflow logs each outcome and schedules any callback requested.
Setup and migration.
International calling is turned on as part of your plan, with rules agreed first. A specialist confirms the destinations you call, the numbers you need abroad and the limits you want in place before any calling is opened.
List destinations and volumes
We review which countries your team calls, how often and from which roles, and quote per-destination rates for your plan.
Confirm international numbers
For each country where you want a number, we confirm availability and any local address or documentation requirements before ordering.
Set dialing rules and fraud limits
Allowed destinations per user or group, blocked destinations, spending thresholds and alerts are configured with you and tested on a temporary number.
Activate and review
International calling is opened for the agreed users. After the first cycle we review usage with you and adjust destinations or limits.
AI in this product
AI on international calling
Calling patterns across countries are reviewed for cost, fraud and quality, and translated summaries help teams follow up.
Destination and plan review
Frequent destinations, call lengths and times are compared with your plan so the recommendation is specific about where a different rate or package would fit.
Unusual pattern alerts
Sudden volume to a new destination, out-of-hours calling or repeated short calls to the same number are flagged for review, with proposed limits applied only after you approve them.
Summaries in your team's language
Where recording is enabled and announced, an international call can be transcribed in the language spoken and summarized in English or French for the team.
Common questions, answered directly.
How does international calling work on a business VoIP system?
An extension dials the international number as usual and the call leaves the platform over carrier routes to the destination country. The business is billed per destination at rates quoted with its plan, and reports show who called where. Because rules are set on the platform, administrators can allow or block countries per user, group or site.
What is an international virtual number?
An international virtual number is a local or toll-free number in another country that rings your business wherever it is. A customer in that country dials a familiar local number and reaches your Canadian team, with routing that follows that market’s hours. Availability, address and documentation requirements differ by country and are confirmed before a number is ordered.
Why block international destinations by default?
Toll fraud typically works by compromising a phone credential and dialing premium-rate or high-cost destinations until someone notices. Blocking destinations by default means a stolen credential cannot dial them, and opening only the countries your team calls limits exposure. Spending thresholds and alerts add a second line of defence, configured with you at setup.

US calling is part of most 3CTel plans. What is included and what is billed per destination is quoted with your plan before activation, so there are no surprises on the first invoice.
In many countries, yes. Availability varies by country and some require a local address or documentation. We confirm what is available for each country you need during planning.
Usually your Canadian business number, or a local number where you hold one in that country. Some destination networks alter or replace the presented number, which we explain for the countries you call.
Destinations are allowed per user or group, high-risk destinations are blocked by default, and spending thresholds and alerts are configured with you. A compromised password cannot dial destinations that were never opened.
Yes. The 3CTel desktop and mobile apps work over an internet connection from most countries, with the employee’s Canadian extension, caller ID and voicemail. Local rules in some countries may restrict VoIP use, which we flag where known.
Messaging on international numbers depends on the country and number type. Where texting is supported for a number, it is confirmed during planning along with the number itself.
