International phone calls on a traditional business phone system are expensive, unpredictable, and difficult to manage. Calls to clients overseas cost multiple times what a domestic call costs. Staff working in other countries have no connection to the main office phone system. Customers in other markets call expensive international numbers and sometimes do not bother. And your finance team has no clear picture of what the international calling spend actually is or which team is driving it.
Telphi sets up international VoIP services for businesses across the US, UK, and Canada that are expanding into new markets, supporting international clients, or managing teams across multiple countries. We configure international SIP trunking, virtual local phone numbers in over 200 countries, competitive international calling rates, and full compliance with local telecommunications regulations in every market you operate in. Our clients cut their international calling costs by an average of 70% compared to what they were paying before.
International calling powered by the global networks of: Vonage, Twilio, Telnyx, Plivo, and Bandwidth.
International VoIP services replace expensive traditional international phone lines with internet-based calling that routes your international calls over the same infrastructure as your domestic calls. Instead of paying per-minute international rates to a traditional carrier, your calls travel over the internet to a local carrier in the destination country and connect to the local phone network at domestic rates.
The practical difference is significant. A call from a US business to a client in Germany that might cost 10 to 15 cents per minute on a traditional international line costs a fraction of that over international VoIP. For businesses making dozens or hundreds of international calls per day, this difference compounds into substantial monthly savings.
But cost is only part of what international VoIP services solve. The other part is presence. When your business calls a client in the UK from a US number, the call often gets ignored because the client does not recognise the international dialling code. When the same call comes from a UK local number, it gets answered. International VoIP gives your business a local phone presence in every country you operate in without requiring a physical office or a separate phone system in each location.
For businesses with staff working internationally, international VoIP connects remote team members in other countries to the main company phone system as if they were sitting in the same office. They use the same softphone app, same extension system, same call routing, and same voicemail. The only difference is their physical location.
A complete international VoIP setup from Telphi covers every aspect of your global calling requirements. Here is what gets configured in every deployment.
SIP trunking is the technology that connects your business VoIP system to the public telephone network in each country. International SIP trunking extends this to multiple countries, routing your outbound international calls through local carrier partners in each destination country so they connect at local rates rather than international rates. Telphi configures international SIP trunks with the right carrier partners for your specific destination countries, volume requirements, and quality needs.
A virtual local phone number gives your business a real, dialable phone number in any country without a physical office there. When someone in France calls your French virtual number, they pay a local call rate and the call routes through to wherever your team actually is. When your team calls a client in France from the same virtual number, the client sees a local French number on their screen. Telphi provisions virtual local numbers in over 200 countries as part of every international VoIP setup.
International toll-free numbers let customers in specific countries call your business without paying any call charges. For businesses with customer-facing operations in multiple countries, toll-free numbers remove the cost barrier that stops customers from calling. Telphi provisions international toll-free numbers in the countries your business needs them and routes them to the right teams.
Telphi negotiates international calling rates through established carrier relationships rather than passing through the standard retail rates most businesses pay. We provide a full rate comparison against your current international calling costs before you commit so you see exactly what you will save before any configuration work begins.
If your business already has established phone numbers in other countries that clients use and recognise, Telphi manages the porting of those numbers to your new international VoIP setup. Your existing international numbers stay exactly the same from your clients' perspective.
Telecommunications regulations vary significantly between countries. Some require local carrier registration before you can provision numbers. Some have specific rules about call recording consent. Telphi navigates the compliance requirements in every country you need to operate in and ensures your international VoIP setup meets local telecommunications law in each market.
We handle the complete setup from assessment through to go-live. Here is exactly how the process works.
We map exactly what your international calling requirements are. Which countries you call most frequently, what your current per-minute costs are, whether you need local numbers in specific markets, whether you have staff working internationally, and what compliance requirements apply. At the end you receive a full cost comparison showing your current international calling spend against what it would be on the new setup, a country-by-country virtual number recommendation, and an implementation plan.
Great for:
Finance directors and operations managers who need to see a clear cost justification before committing to an international VoIP deployment.
We design your international VoIP configuration. SIP trunk selection for each target country, virtual number provisioning, call routing rules for inbound international calls, outbound dialling configuration, integration with your existing VoIP system, and compliance configuration for each market. You review and approve the full design before any provisioning begins.
Great for:
Businesses expanding into new international markets who need a properly configured global calling setup rather than a patchwork of separate carrier contracts.
We provision the virtual numbers, configure the SIP trunks, set up the call routing, test call quality in each target country, and verify that inbound and outbound calling is working correctly in every market before handover.
Great for:
Businesses that need a fully tested international calling setup with no surprises on go-live day.
After go-live, we manage your international VoIP setup. Adding new countries as you expand, managing carrier relationships, monitoring call quality across international routes, updating compliance configurations as local regulations change, and optimising rates as better carrier options become available.
Great for:
Businesses that want one partner managing their entire international calling infrastructure rather than dealing with multiple carriers in multiple countries.
The average business that moves from traditional international calling to international VoIP cuts their international phone costs by 60% to 80%. For businesses making significant volumes of international calls, this is one of the highest-return technology changes they can make. The savings are fully visible from the first month's billing and Telphi provides a before and after cost comparison so the impact is unambiguous.
A virtual local phone number in any country gives your business a credible local presence without the cost of a physical office or a local carrier contract. Clients in other countries call a number that looks local to them. Prospects are more likely to answer a call from a local number they recognise.
Staff working in other countries connect to the same VoIP system as your domestic team through the softphone app. They get a local extension, access to the company directory, the same call routing, the same voicemail, and the same call recording. One system covers every country without separate contracts.
Managing separate carrier contracts for each country creates administrative overhead, inconsistent billing, and different support contacts for every problem. Telphi manages all of your international calling through one relationship. One invoice, one point of contact, one team responsible for making it all work.
