In this guide, we will try the capture the basic of Cloud Telephony, How Cloud Telephony Works , difference between Cloud Telephony and VoIP and it’s benefits across industry  

1. What is Cloud Telephony

Cloud Telephony is a modern business communication system that allows companies to make phone calls using the Internet instead of traditional landlines or mobile networks.

It relies on VoIP (Voice over Internet Protocol) technology or PSTN to transmit voice over the internet, providing businesses with a flexible and cost-effective communication solution.

Cloud Telephony is used by organizations of all sizes because it:

• Improves customer service.

• Reduces operational costs.

• Enables advanced features such as call forwarding, IVR, call recording, and analytics.

2. How Cloud Telephony Works

Cloud Telephony can be used on traditional desk phones, mobile devices, or computers (desktop, laptop, or tablet).

It works through two primary networks:

 2.1 PSTN (Public Switched Telephone Network):

• In countries like India and Middle Eastern nations, regulations do not allow mixing of IP and PSTN calls.
  
  

• These regions use PSTN-based cloud telephony.

2.2 How does PSTN based Cloud Telephony Works

 When businesses migrate to cloud telephony, customers dial a published number (toll-free or mobile) instead of traditional office landlines. Calls are then managed through three possible methods:

1. Forwarding to a PRI line located in the data center.

2. Forwarding to a PRI number directly from the cloud.

3. Forwarding to cloud telephony servers, which support advanced functions such as IVR, call recording, analytics, and CRM integration.

2.1.1 Incoming Call Process

• Customer calls the business number.

• The cloud telephony system routes the call through PRI lines or servers.

• Intelligent call routing ensures customers are connected to the right agent or IVR option.
  
  

2.1.2 Outgoing Call Process

• Agents make calls via the cloud platform.

• Calls are transmitted over the internet or PRI.

• Customers see the company’s official business number (not the agent’s personal number).

• Calls can be recorded, monitored, and logged into CRM systems automatically.

2. IP (Internet Protocol):

• In countries like the United States, calls are fully internet-based using VoIP.

• This method provides high flexibility and is commonly used in advanced economies.

2.2 Traditional PBX vs Cloud Telephony

In the past, businesses relied on PBX (Private Branch Exchange) systems, which required:

• A dedicated PRI line.

• A PRI server.

• Complex on-site infrastructure.

Cloud Telephony eliminates these costs and complexities by moving everything to the cloud. Businesses only need:

• A published cloud telephony number (mobile or toll-free).

• Internet-enabled devices (PCs, laptops, mobile phones)

3. Use Cases of Cloud Telephony

• Remote Workforce: Employees can stay connected with company numbers from anywhere.

VoIP (Voice over Internet Protocol):
A technology that allows voice signals to be converted into digital data and transmitted over the Internet.

Cloud Telephony:
A business communication system that uses VoIP technology but adds additional features such as IVR, call recording, call routing, analytics, and CRM integration.
