In the fast-paced world that we live in, customers expect an immediate response to their service requests. An effective communication system has become a must-have for businesses. Gone are those days when phone systems relied on thick cables and complicated hardware systems to build a connection.

Need a reliable and affordable business phone system? Look no further than DialerHQ.

With a rapid increase in internet penetration, cloud based phone systems have gained popularity and prominence. The article explains several aspects of cloud based phone system for small business, including features, pros and cons, and popular cloud-based phone service providers. 

What is a Cloud Based Phone System?

Technically called a Voice over Internet Protocol (VoIP), a cloud based phone system lets you make calls over the internet. Communication happens over the internet, unlike traditional analog phone systems that use copper cables or optical fibers to establish a connection. Because these systems do not require on-premise installations, hardware systems, and infrastructure, cloud based phone systems are cost-effective. 

Cloud based phone systems are hosted in off-site data centers and can be used with conventional phones through smartphone applications, adapters, or VOIP phones. Traditional phone systems use Private Branch Exchange (PBX) with cables and switches to collect and store data and information. In cloud phones, the PBX is located on the cloud system. 



When compared to traditional phone systems, deployment of cloud based systems is relatively easy. As it does not require complex hardware installations at the premises, cloud phones help businesses save a major chunk of their investments in building communication infrastructure. The cost of maintenance is also lower as the communication system is managed off-site, outside the organizational premises. 

How do Cloud Based Phone Systems Work? 

In cloud based business phone systems, calls are transferred as signals between two IPs (Internet Protocols).

Cloud based phone systems dissect your calls into small audio packets that are then transmitted as data to the recipient. Using the cloud based Private Branch Exchange, the VoIP phone provider routes the call to the VoIP phone or landline system. When the data reaches the recipient, they are converted into voice signals. This is unlike the traditional phone systems that transmit voice through cables and networks. 



Cloud based calls can be made using any of the following devices. 

  • Smartphones: You can use Google Voice, Skype, and other applications to make calls over the internet using your smartphone.
  • VoIP adapter: By using a VoIP adapter plugged into either the router or phone socket, you can make calls over the internet using traditional landline phones.
  • Computer Applications: You can use applications like Google Voice, Skype, or FaceTime to make calls over the internet using your computer.
  • An exclusive VoIP phone: Dedicated VoIP phones function similarly to traditional VoIP phones but let you make calls over the network instead of a phone line using optical fibers or copper cables.

Features of Cloud Based Phone Systems

A notable advantage of cloud based phone systems is that they offer extensive features compared to traditional phone systems. Following are some of them.

Advantage of Cloud Based Phone Systems


1. Unified Communications

Cloud based telephone system brings together various business communications features like voice mail, video conferencing, automatic call distribution systems, etc., under a single umbrella. Cloud phones can also be integrated with CRM, web apps, mobile apps, etc. 

2. Video Conferencing 

Video conferencing is an important requirement for businesses as hybrid and remote work is leading the new normal. Cloud phone systems offer video conferencing options as a part of their package and the happy news is you don’t have to pay extra.  

3. International Calling

As cloud phones route calls over the internet, making international calls is as easy as making local calls. That you don’t have to pay extra is the icing on the cake. This is beneficial to businesses that have offices in multiple locations across the world as well as to those who are selling their products and services beyond the bounds of their country. 

4. Call Transfer

A significant advantage of a cloud based telephone system is the ‘never miss a call’ or the call transferring feature. You can route calls to multiple extensions at the same time or to both desk phones and smartphones and let the receivers decide how they would want to answer the call. 

5. Artificial Intelligence

Cloud phone services are leveraging the power of AI to enhance customer service quality and perform several functions, including speech-to-text, IVR operations, and sentiment analysis.

6. Instant Messaging 

Cloud phones allow businesses to communicate with the caller through text messages. Instant messaging allows the user to pass the information in writing so it can be referenced later. 

7. Cloud Communication 

In cloud phones, calls are routed through the internet and data is stored in the third-party cloud service provider. It has instant messaging, telephony, voicemail, video conferencing, etc., in its bundle of service offerings. 

8. Auto Attendant

The cloud based phone system has auto attendant features that act as a virtual receptionist that helps receive, answer, and transfer incoming calls to relevant departments and extensions based on caller responses. This reduces employee burnout and enhances the productivity of the customer service team.

9. Collaboration

Cloud phones have several options, like video conferencing, audio conferencing options, file sharing, and other tools that help bring together different teams and drive collaboration.

10. Voicemail-to-email

The voicemail-to-email feature of a cloud phone system helps convert the voicemail into an audio file and send it to an email address. Without using the voicemail box, the recipient can access the voicemail. As the voicemail is within the data limits, the recipient can refer to it whenever needed. 

Things to Consider Before Investing in a Cloud Based Phone System?

Cloud based business phone systems are affordable, cost-effective, and easy to deploy compared to traditional phone systems that demand upfront investment and maintenance.

Before you decide if you should shift to using a cloud based phone system for small business, you should evaluate the following factors. 

Consider Before Investing in a Cloud Based Phone System


1. Infrastructure

As cloud based phone systems operate over the internet, all that you need is a desktop or smartphone. So, if you have just started to build a communication system for your business, cloud based phone systems are a great choice. 

On the other hand, in case you have built a traditional phone system, you must consider how best you can retrofit the cloud-system components to the traditional system. Evaluate the compatibility options of the cloud phones with your service before you make the investment decision.

2. Installation and Maintenance

Cloud based phone service systems reduce the cost of installation and maintenance. VoIP providers offer add-ons and extra features like AI sentiment analysis, video calls, etc. at premium costs. So, before selecting a service provider, ensure that you evaluate the features they offer and the costs before you make a buying decision. 

3. Data Control

In cloud based business phone systems, data is stored, managed, and accessed by a third-party cloud service provider over the internet. This is unlike the traditional systems that store data on a local server. So, cloud based phone systems reduce the need for servers and storage infrastructure. 

This is helpful for small businesses that may not be able to afford to invest in dedicated servers for their business phone system. On the other hand, if you want complete control over data, you should carefully evaluate the security policy of the provider before you buy. 

4. Internet Connectivity

As cloud telephone systems operate over the internet, you need a stable internet connection. In case you have poor internet connectivity, you must first work on improving the connectivity before investing in a virtual phone system
