What is VoIP Software? 

VoIP Software is a virtual communications application that lets users make/receive calls over the Internet instead of the landline PSTN network copper wiring system. 

VoIP offers significant cost savings, flexibility, and scalable advanced calling features that traditional landlines can’t. Call forwarding, multi-level IVR, editable call flow design, and even video conferencing are considered standard VoIP features.

VoIP platforms are also device-agnostic, meaning users can conduct business communication across numerous devices including desktop and laptop computers, (via softphone interface) smartphones, tablets, and analog desk phones (hardphones.) 

Note that VoIP is intended to improve both internal and external communication, as many providers offer features like instant team chat messaging with user presence, team collaboration tools like whiteboarding and screen sharing, and file sharing and co-editing. 

The terms VoIP, IP telephony, virtual telephony, virtual calling, and online phone systems are used interchangeably. 

There are three main types of VoIP services: Cloud VoIP, On-Premise VoIP, and Residential VoIP.  Let’s take a deeper look at what separates them below. 


Types of VoIP

Below is a description of the key types of VoIP.

  • Cloud VoIP: Cloud VoIP or hosted VoIP is a phone service that lets you make calls through the internet. It is one of the most cost-effective formats of VoIP software because it is hosted by a third-party provider and reduces the cost of service by eliminating the need for dedicated hardware. Most cloud VoIP providers offer advanced business features like auto attendant, advanced call routing, and call analytics
  • On-premise VoIP: On-premise VoIP differs from its cloud counterparts in that it is installed at your company's office. This gives you more control in terms of security, but you’ll need to shell out more cash upfront for the necessary hardware and maintenance. Scaling on-premise VoIP is more difficult and expensive than the one hosted in cloud. You will need to buy more hardware and manage all configurations yourself.
  • Residential VoIP: Residential VoIP is a voice service for your home that works over the internet. People choose it over landline because it's inexpensive, portable, and has more features. In order to use VoIP at your home, you'll need to have fast and reliable internet connection and some hardware.


Benefits of VoIP Software

Why are so many businesses making the switch from POTS to VoIP software? See the benefits below.


Cost Savings

VoIP software offers major cost savings when compared to landline phones. One of the most significant savings comes from eliminating the need for hardware (when choosing hosted VoIP services.)

Traditional PBX hardware can easily cost between $500-$2,000+ per user, and additional hardware can cost between $100-$1,000 per phone. However, VoIP makes use of existing VoIP equipment, (desktop computers, desk phones, smartphones, routers etc.) and most additional IP phone and hardware needs are managed by the PBX provider.

Plus, because VoIP places calls over the Internet, users will see major savings when it comes to long-distance phone calls. Since unlimited calling in the US and Canada is included in VoIP monthly plans, users can quickly shave off close to $500/month on long-distance costs. Most VoIP plans also include a set number of monthly toll-free minutes.

VoIP also helps to cut costs associated with:

  • Maintenance
  • Additional phone lines
  • Teleconferences
  • International calls
  • Startup communication costs

For more details about VoIP cost savings, see our post on the Advantages and Disadvantages of VoIP.


Scalability and Flexibility

Scalability is another huge advantage of VoIP.

Instead of paying for features or seats they don’t yet need, companies can choose specific plans and add-ons thanks to a la carte or bundled VoIP services.

Tiered pricing makes it easy for companies to scale their VoIP services as they evolve, adding new communication channels, integrations, advanced features, and more. Plus, users can instantly add these new features without any downtime or added IT costs.

VoIP software makes it easy to not only communicate with a geographically diverse remote workforce but also to monitor their activity and progress.

Features like one-click video meetings, file sharing, and editing, chat messaging, audio conferencing, live analytics, and user presence updates make it easy to communicate and collaborate with team members no matter where they are.

This also means customers are far more likely to be able to reach the agent or department they need on their first contact.


Advanced Features

Traditional phone service offers a few basic call handling features like call holding, three-way calling, voicemail, and caller ID.

However, VoIP offers not only more communication channels but also far more advanced and high-quality communication features than standard phone service.

Users can create and edit custom call paths, provide a high level of customer self-service with IVR, (Interactive Voice Response) and rely on detailed analytics to get insight into common customer issues, productivity levels, average call handling time, and more.

We’ll speak more about VoIP features later in this post, but additional information is available in our piece on the best VoIP Features.


All-in-One Communications

About half of today’s consumers use multiple communication channels when interacting with a business.

VoIP offers all-in-one omnichannel communications that let customers choose their preferred method of contacting support or sales departments. Popular channels include voice calling, email, SMS text messaging, live chat, video calling, and even social media messaging.

Regardless of which channel customers and agents connect on, communication and order history, notes, and other essential customer data from past interactions and CRM systems is synced and displayed. This allows agents and customers to pick up exactly where they left off on past conversations, even if those conversations took place on another channel.

VoIP software providers also offer extensive application integrations, meaning that companies can integrate existing third-party communication and collaboration tools into their VoIP interface.

This eliminates the need to choose between having to learn how to use new software or having to forgo essential functions. Instead, users can access all of their preferred tools within one unified dashboard.


VoIP Software Essential Features

VoIP software providers offer advanced features that aren’t available with traditional office phone systems.

Key features to look for include:

  • ACD and IVR: Automatic Call Distribution (ACD) and Interactive Voice Response (IVR) both eliminate the need for callers to speak to an agent directly. Instead, these features use AI, speech recognition, automation, and pre-recorded announcements to direct calls, offer input from the helpdesk, and even let customers pay bills over the phone via voice responses or dial tone input.
  • Visual Voicemail: In addition to voice mailbox routing, VoIP systems offer visual voicemail, which transcribes voice messages and sends them as emails or SMS messages. Users may also receive an MP3 recording of voicemail messages in emails, set up voicemail notifications, and can quickly respond to priority messages.
  • Call Recording and Transcription: VoIP systems offer automatic and on-demand call recording and transcriptions. Call transcriptions can be searched to determine keywords, the call quality and quality of support received, the common customer issues, and more.
  • Advanced Call Handling: In addition to call transfers, call forwarding, and Do Not Disturb, VoIP call handling features allow users to block numbers, set advanced call routing strategies, create ring groups, schedule automatic callbacks, manage call queues, and more.
  • Video Calling: Today’s business phone systems also include video conferencing, generally for between 100-250 users. This allows for face-to-face meetings anywhere, at any time. Meetings can be scheduled ahead of time, or users can instantly transition to a video call from a chat message. As with voice calls, video calls can be recorded and sent to participants after the meeting ends.
  • Team Collaboration Tools: Team chat messaging, which allows for public/private channels, user tagging/mentions, polls and surveys, and more, all make instant, real-time communication easy. Additional team collaboration tools like screen sharing, remote screen control, file sharing, and co-annotation, task management, and even workflow management are included with VoIP systems. These tools are available during audio and video calls as well as the unified interface. Team chat messaging, which allows for public/private channels, user tagging/mentions, polls and surveys, and more, all make instant, real-time communication easy.
  • Virtual Extensions and Phone Numbers: Many VoIP systems offer unlimited user extensions in addition to local telephone numbers, toll-free numbers, vanity numbers, and even local presence in multiple countries. Direct Inward Dialing and company directories make it easy for callers to find the exact extension or numbers they need.
