What is internet phone service?

A cloud internet phone service, as the name implies, is a phone system rooted in the internet. It allows users to make and receive calls from anywhere using their laptop or mobile device. It provides small businesses and enterprises with the security, mobility, flexibility, and advanced call features that aren’t possible with on-premises phone systems.

How does an internet phone work?

Here’s how internet calling works:
  1. The voice signals you generate are converted into data packets.
  2. These packets travel over the network and out through the internet until they reach their destination.
  3. VoIP converts the packets back into voice signals for the person on the other end to understand the message.
Internet phones can either be actual desk phones that look much like your traditional phones or any VoIP-enabled devices connected to the internet, such as mobile phones, laptops, or tablets.

Cloud-hosted PBX

Cloud-hosted PBX helps businesses manage incoming calls through several features: auto-attendant, inbound and outbound caller ID, advanced call routing and forwarding rules as well as call screening, blocking, recording, and waiting. Businesses can even set up different answering rules for different times of the day. For example, all calls during business hours are answered and routed, while calls after hours can be sent straight to voicemail.

Audio and video conference

Conferencing is especially useful for companies with mobile employees or multiple locations. It lets you and your team host and join audio or video meetings from anywhere through their laptops, cell phones, or any mobile devices as long as they have a stable and high-speed internet connection. It can be used to conduct interactive webinars as well.

What you need to know about internet phone service

An internet phone call is one that is placed over the internet and made possible by VoIP (Voice over Internet Protocol) technology. There are multiple ways to make internet calls, including:
  • Through a landline phone with an analog telephone adapter (ATA) - A phone adapter connects a landline phone to a VoIP system to enable internet calls. Just plug your phone cable into the device, and you’re good to go.
  • From PC to PC - Download a VoIP-enabled program, set up an online account, and start making internet calls. Call quality depends heavily on your infrastructure and bandwidth, so it doesn’t always make for an ideal business phone system, especially for small- and medium-sized businesses. Examples of this type of VoIP programs are Google Voice and Facebook Messaging.
  • From PC to phone - Partner with a third-party software provider to connect your computer to a landline phone and make PC-to-phone calls. You’ll be able to leverage their VoIP services for a price which is still considerably lower than what a traditional phone company would charge.
  • Using softphones and apps - Connect to VoIP using any handheld device. This setup is ideal for businesses with a number of field or remote workers.
Unlike PSTN, VoIP doesn’t require a dedicated circuit to maintain a call between two people. This is a major reason why long-distance calls, especially international ones, are so expensive with PSTN. You can just imagine how call costs drain certain businesses dry, like those that house a contact center.
On the other hand, VoIP uses packet-switching technology, wherein data packets (voice signals) take different routes to reach their destination. That only means the cost isn’t based on time or distance. There are no expenses to cover circuit and phone infrastructure.
So if your company makes a ton of long-distance calls, you are bound to generate huge savings with VoIP. That’s money that can be used for other important aspects of the business.
With all the benefits that can be had from a VoIP phone system, one might wonder if the days of traditional phone systems are numbered. Is it only a matter of time before every business will have fully embraced VoIP technology?
Full adoption may take a while, but the future of business communications and connectivity indeed points to packet-switched networks. VoIP continues to change the way businesses communicate and collaborate, and it’s up to you to capitalize on this technology and stay ahead of the competition.
There may be “hurdles” along the way, but you can rest assured that experts are stopping at nothing to refine this technology. For as long as companies like RingCentral are on top of the game, internet calling can only get even more sophisticated and accessible to organizations of any size—startups, small businesses, and enterprises alike.
Monthly fees can go as high as $100 per phone line, depending on the phone carrier. Since landline phones rely on dedicated copper wires, adding more lines requires additional hardware, which in turn means additional costs. That’s $500 in your monthly bill if you have five lines. 
On the other hand, the price of internet phone systems goes at a much lower rate. Additionally, because VoIP phone systems rely on the internet instead of public-switched telephone networks or mobile networks, they can support multiple lines, depending on the strength of your internet connection.
There are many other ways internet phone services let you save money. Here are a few more of them:
  • Hosted VoIP providers typically don’t require setup fees.
  • You don’t need to pay extra for maintenance, repairs, and upgrades.
  • VoIP uses the internet, so international and long-distance calls are much cheaper.
  • Bringing your own device to work? VoIP supports BYOB initiatives, which means you can use your Samsung or Apple devices to access company platforms.
Talk to a potential vendor about their phone plans and discover lower-priced options that fit your business needs. For instance, if your business requires constant communication with your offices in the USA and Canada, note that there are companies like RingCentral that offer an international calling plan with unlimited calls within the said countries, even Puerto Rico.
The big question of security has been thrown at VoIP technology, especially since it’s started to gain traction. It’s just a reality we have to deal with in this increasingly connected world. The internet, after all, is ever susceptible to various security issues. Let’s take a look at the common ones.
  • Service theft - Hackers can gain access to your VoIP service and network through VoIP phones. Once in, they can steal passwords, usernames, and personal information. They use the data they have stolen to perform all sorts of fraudulent acts, such as identity theft, phreaking (stealing of service from the provider or using it and passing the cost to another user), and intentional disruption of service.
  • Denial-of-service (DoS) attack - In a DoS attack, your network or device is denied service or connectivity. Hackers choose one target at a time and consume its bandwidth or overwhelm its network until it’s forced to shut down. This is usually done to damage brand reputation, extort money, and, in some cases, just for kicks.
  • Call tampering - Here, the hacker targets the communication stream with the intent of degrading call quality, dropping the call, forcing a delay in voice signaling, and other critical issues. This is done by sending a stream of data packets through the PBX network. By intercepting call signals, the hacker can change the encryption key to their own public key, causing further privacy and authentication issues.
  • Malware and viruses - VoIP exists within the realm of computer networks and is therefore exposed to the same risks as computers themselves. These include malware, which takes up network bandwidth, and viruses that wreak havoc on software (softphones included) to compromise its performance. A kind of malware that has the capacity to self-propagate is called a worm. It infiltrates your VoIP network, PBX, databases, and other systems to access important data and make your business vulnerable to other attacks.
  • Man-in-the-middle attacks - Hackers use sophisticated software tools to mislead customers into thinking they are accessing a genuine server. The attackers position themselves in a conversation between the client and the server in order to intercept or manipulate data. By eavesdropping or impersonating one of the parties, they can collect sensitive information.
  • Vishing - If you’ve heard of phishing in email, this is its voice-based equivalent. With vishing, the attacker uses ID spoofing to pretend they are a reputable business (e.g., a government or financial institution) and trick you into giving up sensitive information.
Simply being aware of all these threats should already put you in a prime spot to prevent or combat them. From establishing strict standards in password setting to implementing monitoring systems, there are numerous techniques you can implement to secure your network.
The thing is, as IT experts mitigate one security risk, hackers are able to find other ways to go about it. It almost feels like they are always a step ahead. But this shouldn’t be much of a concern when you get a number from a VoIP provider, as they follow stringent security measures and practices.
RingCentral, for instance, takes pride in providing optimum security with Tier 1 network centers and round-the-clock monitoring to avert any form of attack or disruption. This is a major reason why the company continues to lead the way in business communications solutions globally.
