VOIP for International Calls

Introduction to VoIP

Voice over Internet Protocol (VoIP) refers to making and receiving phone calls over the internet rather than traditional analog phone lines. VoIP converts analog audio signals into digital data that is transmitted over the internet. It allows both businesses and residential users to benefit from cheaper calling rates, advanced features, and greater flexibility compared to traditional landline or mobile phone services.

Definition of VoIP

Simply put, VoIP enables phone communication via the internet rather than copper phone lines. It translates voices into specialized packets of data for transmission over broadband connections instead of old-fashioned switched telephone networks.

Dedicated VoIP providers offer the capability to place calls directly from a desktop phone or softphone app just like traditional phones but routes calls over the internet. IP telephony protocols replace circuits in order to connect phone users anywhere worldwide at a fraction of the cost using innovative technology.

Benefits of VoIP over Traditional Phone Lines

VoIP introduces some major advantages over conventional telephony:

Lower Costs – Avoiding telephone company services cuts international call costs by up to 90% as VoIP utilizes cheap, ubiquitous internet pipelines.

Increased Flexibility – Software phone apps enable calling from anywhere with WiFi access not just desks. Built-in features boost productivity.

Enhanced Scalability – Cloud VoIP systems easily and affordably scale to accommodate growth way more than legacy PBX equipment ever could.

Scalability and Cost-Effectiveness

Two major advantages VoIP solutions hold over traditional phone services involve scalability and cost savings. As internet speeds have soared globally over the past decade while broadband penetration continues rising, VoIP call quality and reliability now matches conventional landlines.

Meanwhile, IP telephony costs remain minimal because voice data travels over cheap, abundant internet bandwidth rather than tolled traditional switched networks. This fundamental economic and infrastructure advantage allows hosted VoIP services to gain widespread mainstream adoption across businesses of all sizes as well as residences.

VoIP for International Calls

With burgeoning globalization, entertaining customers, partners and remote employees abroad continues growing exponentially each year. But astronomical international calling rates levied by incumbent phone companies prompt massive bills. Migrating international calls to internet-based VoIP solutions slashes costs by as much as 90% over conventional long distance while unlocking more flexible reach.

Cost-Effectiveness for Businesses and Individuals

Traditional international calls carry some of the highest per minute rates often exceeding $1/min – a 15 minute weekly client call abroad costs over $75/month. But the same call over VoIP would run under $5 symmetrical for both parties. These incredible savings add up allowing small businesses to affordably communicate overseas to boost sales.

Global families also take advantage of consumer VoIP options to connect affordably and more often. Some leading business platforms even offer free international calling bundled into low fixed monthly rates for unlimited minutes. Charitable and relief organizations also harness VoIP solutions to help coordinate essential disaster recovery responses more economically enabling precious funds to be allocated for actual aid work rather than astronomical phone bills.

Comparison of VoIP International Call Rates

Most residential and business VoIP providers publish international calling rates by country on their websites for full pricing transparency allowing easy rate comparisons. Below illustrates sample per minute rates to Britain for VoIP services versus conventional phone companies:

Provider Per Minute Rate
Verizon Landline $2.50
AT&T Long Distance $3.18
Skype $0.023
Google Voice $0.07
Vonage Business $0.019
8×8 Free
RingCentral $0.029

As evident, VoIP rates equate to only a tiny fraction of traditional international call rates from telephone companies. Those rock bottom VoIP rates add up to major cost reductions especially for regular international callers.

Flexibility and Accessibility

Another benefit using VoIP for global communications introduces involves vastly enhanced location flexibility untethering callers from physical desks and traditional handsets. VoIP apps turn any smartphone, tablet, laptop into essentially a portable business phone system able to ring anywhere with WiFi access around the world and across international borders seamlessly.

Most providers allow choosing unique virtual business numbers from 50+ countries linked to accounts. This means a small business in Dallas could transparently present London or Sydney numbers on its website and routes to mobile devices wherever staff travels internationally. Some services even offer unlimited free calling minutes between international numbers on the same account in loads of countries making cross border team communications simple and affordable.

Handy features like internet faxing, digital voicemail to email, call analytics and even toll-free international customer service numbers provide additional useful business functionalities realizes huge savings and convenience communicating overseas.

How VoIP Works for International Calls

Under the hood, VoIP solutions utilize the ubiquitous power of the global internet ecosystem combined with digitized packet voice protocols to transmit calls internationally at much lower costs compared to monopolistic traditional telephone infrastructure.

Utilization of the Internet for Call Transmission

Rather than dedicated end-to-end circuits, VoIP technology breaks down calls into tens of thousands of tiny digital data packets labeled with unique destination codes. These packets traverse across the interconnected internet worldwide following optimal pathways based on real-time traffic conditions automatically.

Internationally, voice packets exchange between local data centers in different countries connected via fiber optic submarine and terrestrial cables just like normal internet data does. Last mile data connections tie corporate or residential internet connections into local exchanges granting affordable access to global calling.

Dialing Format for International Calls using VoIP

When dialing international numbers over VoIP platforms, the same standard international calling format applies:

(International Call Prefix + Country Code + Local Number)

However, most business VoIP providers require specifying extensions for every call for proper routing and monitoring. Many also mandate including a leading 0 before the number as well. This format looks like:

0(Extension) + (International Call Prefix) + (Country Code) + (Local Number)

So calling a mobile number in London England from a 1000 extension might follow:

01000 + 44 + 20 3389 8425

For even faster international dialing, VoIP services also allow pre-programming speed dial buttons for frequently called overseas contacts storing tedious number strings. Admins can control permissions like international calling and extension dialing on a user by user basis as well centrally.
