A VoIP app is a software program installed on a computer or smartphone that enables you to make and receive phone calls. You’ve most likely used one before. Skype, Nimbuzz, and Line are popular personal VoIP apps.

For low-cost communications, big and small businesses have used Voice over Internet Protocol (VoIP) for years. VoIP enables companies to offer better phone service at a lower cost, with dozens of premium functions built-in.

You can use VoIP applications to place calls from virtually any device, including your PC and Mac. You can also send messages and files or conduct video conferencing. Download the App on your mobile or desktop, and they are ready to use.

The Session Initiation Protocol (SIP) is a communications protocol for real-time, two-way voice communications used by many VoIP apps.

Businesses are using VoIP apps for the following reasons:

  • Mobility: For individuals who are always on the go, online VoIP applications are ideal for communicating. One of the primary reasons for their popularity is that they allow you to communicate from anywhere with a mobile device and an Internet connection over WiFi or a 5G network.
  • Accessibility: Making phone calls over the internet using VoIP applications has several advantages. Most apps work on various operating systems and devices to utilize them on your computer, landline, and cell phone.
  • Cost-effectiveness: VoIP solutions are both free to download and less expensive (especially over time) than traditional PBX phone systems in the long run, both upfront and over time. You won’t technically be able to make free calls, but certain providers do give you unlimited calling on their plans.

Here’s a list of some of the most effective SIP and VoIP apps of 2022.

Although Freshcaller offers a free plan, you must pay almost just to use it. As a result, you’d have to purchase a number and pay for incoming and outgoing minutes.

What are the Benefits of Using VoIP Apps?

Here are the most popular advantages of utilizing a VoIP app to help people understand why many individuals are switching to it.:

  • User-Friendly: VoIP applications may be installed on almost any device, including smartphones, tablets, and even desktop or laptop computers. The popularity of VoIP applications is because of their simplicity of use and rich features. Some VoIP applications may remember and store your SIP credentials on your device, so you don’t have to every time.
  • Feature-Rich: Multi-level auto attendants, HD call quality, conference calls, visual voicemail, hold music, call forwarding, and more are features offered by VoIP apps. Only one dashboard is required to manage and configure VoIP applications for an organization.
  • Flexibility: The lack of communication and collaboration, according to Buffer, is one of the main problems users confront in the remote work culture. The multi-platform support feature of VoIP apps is one of the most valuable assets in resolving this issue. Users may be logged in from many devices at once using these applications. Data will automatically sync between devices, making it easy for employees to continue conversations or collaborate on projects from any location using a single VoIP number.
  • Low Cost: VoIP apps are often free to download, and monthly subscription costs are much lower than traditional phone service providers.
  • Efficiency: VoIP applications allow users to manage their time more efficiently with features like visual voicemail, which eliminates the need to listen to voicemails in their entirety to determine the necessary actions. Conference calls save time by gathering several people in one call rather than scheduling multiple calls, and voice messages can be sent and received without making or taking calls.

How do VoIP Apps Help You in Business?

One benefit of VoIP is that it treats long-distance calls and local calls in the same way. Instead of charging businesses for calls made outside their area code, many modern VoIP services offer unlimited US-to-US phone conversations—as long as you have a US-based business phone number.

Here are the other ways VoIP can help your business, especially in SMS Marketing:

  • VoIP technology may connect several locations and distribute the workforce: VoIP phone numbers are not connected to a specific telephone, unlike traditional telecoms. It implies that users may make VoIP calls from anywhere as long as they have access to the internet. Also, you don’t need to purchase new business phone numbers for each branch or facility you have in your company.
  • VoIP can scale up or down based on your business needs: VoIP may also adapt to the demands of your company. While a single phone number can connect several locations and a dispersed workforce, it does not imply that firms must stick with just one number. New phone numbers may be readily purchased and assigned to departments or people based on their requirements.
  • VoIP helps you keep your competitive edge: According to Nemertes Research, organizations that have fully transitioned to VoIP have seen an increase in productivity of 11.5%. VoIP applications can be integrated with other software programs used in the workplace, such as customer relationship management (CRM) and enterprise resource planning (ERP).
  • VoIP can help your business save money: VoIP services are often much cheaper than traditional landlines and cell phone plans. A study by PCWorld found that the average small business could save $560 per year by making the switch to VoIP. More so, VoIP providers don’t require you to purchase new equipment, and they often offer flat rates for unlimited minutes.

What Devices do VoIP Apps be Used in?

VoIP apps may be used on a variety of devices, including:

  • Personal Computers: Most VoIP applications are available as desktop software that can be installed on your computer. It allows you to use your phone number and make calls from your computer.
  • Smartphones: VoIP apps are also available as mobile apps installed on smartphones and tablets. You can make calls and send messages using your phone number from your smartphone.
  • Tablets: Many VoIP apps are also available as tablet apps, which allow you to make calls and send messages from your tablet using your phone number.
  • Internet-connected TVs: Some VoIP apps are available as apps installed on internet-connected TVs. This allows you to make calls and send messages from your TV using your phone number.
  • Desktop Phones: Some VoIP providers offer desktop phones that can be used to make VoIP calls. These phones connect to your computer and use your internet connection to make calls.
