What Is VoIP?


VoIP is a technology that allows you to make & receive calls directly over the Internet instead of using traditional phone service. It works by transforming your speech into a digital signal and then compresses it to transmit it through the internet.

After compressing the digital signal, the service provider directs the call to the receiver number. The digital signal is then converted back to the analog sound that enables the receiver to hear you and start conversations. Using VoIP over traditional phone systems is very beneficial as it also has some additional features other than voice calls. 

As a whole, the different features VoIP provides are call forwarding, call barging, global calling, sending and receiving voicemails, call transfer, call history, using multiple phone numbers, live call monitoring, integrations with popular CRMs and business tools, etc. 

What Is UCaaS?


UCaaS is a cloud service that combines multiple communication channels and collaboration tools into the same system. Using UCaaS services we can combine various tools to streamline business communication and greatly enhance the rate of our work productivity. 

In contrast to VoIP, whose main functionality is slightly limited, UCaaS integrates various communication channels like voice calling, video calling, instant messaging, file sharing, desktop sharing, etc, to create a hub for all communication needs.

VoIP Vs UCaaS. What is the Difference?

The big difference between UCaaS and VoIP is that VoIP basically gives you an option for your telephony needs, but with UCaaS, you can use various communication channels in one place, including VoIP calls.

So, instead of just telephony features, UCaaS gives you a platform where you can access and manage different communication tools altogether. 

With VoIP, you can get a business phone system, and if you wish, you can pay extra for more features like additional phone numbers or more/special calling features. However, if you want more advanced communication tools, you have to consider upgrading to UCaaS which will provide you with a wider range of communication channels and more advanced calling capabilities.

Common Features of VoIP and UCaaS

Features of VoIP

VoIP systems are not only for making voice calls. With VoIP, you can access additional options to enhance your communication over the Internet. Here are some of the features commonly associated with VoIP:

  • Virtual Numbers: Many VoIP services provide virtual numbers. Virtual phone numbers are phone numbers that are not tied to a physical location and work over the Internet. These numbers are a great way to expand your business reach or to make it easier for customers to call you.
  • Call Forwarding: If you can’t pick up an incoming call, call forwarding helps you redirect that incoming call to another VoIP number. Again, the number to whom the call has been redirected can redirect the call to another number until someone picks up the call.
  • Call Barging: Call Barging feature allows you as a supervisor to join live calls between two individuals (can be the agent and the client) which helps you supervise them and handle any problems the agents have in real-time. This feature is more useful for you during customer service.
  • Global Calling: Global calling enables you to make calls to other countries, which helps you connect with your loved ones as well as conduct business meetings. Also, using VoIP is very cost-effective as VoIP offers calls through the Internet, which is cheaper than phone lines.
  • Using Multiple Phone Numbers: This option will help you to access multiple virtual numbers from a single interface. Having multiple numbers will benefit you by separating your personal number from your business number.

Features of UCaaS

UCaaS is a complete package of different communication tools that provides you with all the features you need in communication in one single UI. Here’s a breakdown of all the key features of UCaaS:

  • Video Conferencing: With video conferencing, you can have virtual face-to-face meetings with others and see and hear each other in real-time. This feature will make it easier for you to collaborate, discuss ideas, and share information. 
  • Instant Messaging: Instant messaging enables you to have real-time text-based conversations with individuals or groups. It’s like sending quick messages back and forth, similar to texting or chatting. 
  • File Sharing: File sharing will provide a secure way to share documents, presentations, and other types of files within the communication system. With this feature, you can easily upload and share files directly within the UCaaS platform which will simplify collaboration for you.
  • Team Chat: Team chat features allow you to create group conversations with your colleagues, enabling you to discuss projects, exchange ideas, or coordinate tasks. It’s like having a virtual chat room where team members can communicate in real-time. 
  • Desktop Sharing: Desktop sharing allows you to share your computer screen with others during meetings or calls. This feature is helpful when you want to give presentations, demonstrate software or processes, or troubleshoot issues.

Benefits and Drawbacks of VoIP

If you can’t choose between VoIP and other communication channels, choose VoIP! Because it provides more benefits over other communication channels for your business. So, here are some benefits of VoIP:

  • Cost Saving: One important benefit of VoIP is you can save a lot of money on buying and maintaining equipment; instead, you can use cloud-based solutions. Using these flexible and scalable cloud technologies will be more cost-effective for you, and you can also quickly build your communication setup to your needs. 
  • Scalability: VoIP’s main purpose is to make it easier for you to change and succeed. As your businesses get bigger or smaller, VoIP will help you with a flexible solution to fit your needs and adjust your communication setup. This flexibility helps you grow and adapt to different market situations. 
  • Flexibility And Mobility: Another benefit of VoIP is that it makes it easy for you to work from anywhere without losing your ability to communicate with others. That means you use your phone system anywhere you have an internet connection. So, whether you’re at home, on a trip, or at a café, you can still answer work calls.
  • Feature-Rich Option: With VoIP, you can access lots of features that make calls more interactive and useful. Having VoIP is like having a big toolbox full of features for your communication. You can access features like call routing, auto attendants, call recording, call analytics, using multiple phone numbers, live call monitoring, etc.
  • Eliminates Wiring Charges: A great thing about VoIP for businesses is that it gets rid of the costs of installing and maintaining phone lines. With VoIP, you don’t need phone lines to communicate because everything is done through the Internet. So, by using VoIP, you can save money by not having to pay for extra wiring. 

As VoIP has some advantages, it is also important to understand its disadvantages, which are:

  • Dependence on Internet Connectivity: One downside of VoIP for businesses is that it relies on having a good Internet connection to make and receive calls. So, if your internet is down, you won’t be able to use your VoIP phone system until it’s back up and running.
  • Latency And Jitter: Latency and jitter happen when you send data packets, and they get delayed in being sent or put together incorrectly. But these problems can happen even if your own network is working fine. The reason for that is large internet networks sometimes need to adjust the paths of data to make sure it gets where it needs to be.
