A business requires consistent and reliable communication to connect with its clients at all times to satisfy their needs and deliver top-notch services. 

With everything being rapidly digitized it is no wonder that even telecommunication systems have started to rely on the internet and rightly so, because cloud-based phone systems are far more advantageous in terms of flexibility, scalability, and operability.

In this article, we shall look at what cloud telephony is, and pros and cons of cloud telephony, and how can one use it to their advantage.

Now, let’s begin.

What is Cloud Telephony?

Pros and Cons of Cloud Telephony

Cloud Telephony, also known as Hosted Telephony,  is a cloud-based phone system that requires an internet connection to run. Cloud telephony uses VoIP (Voice over Internet Protocol) technology to make calls.

Traditional PBX (Private Branch Exchange) phone systems require extensive hardware and complex infrastructures. They are difficult to maintain, and the phone costs are excessively high for international calls.

However, when it comes to cloud telephony, all one requires is a reliable high-speed internet connection. Cloud telephony is more scalable, integrable, and flexible in terms of its infrastructure, cost, and functionalities.

Since more businesses rely on the Internet to reach their clients, cloud-based telecommunication systems are expected to thrive even more in the upcoming days.

How Does Cloud Telephony Work?

Initially, a company selects a service provider and a suitable subscription model for cloud calling.

A cloud telephony VoIP system mainly requires the following components:

  • A high-speed internet connection and high bandwidth
  • Advanced equipment: Dedicated Routers, VoIP phones (also known as IP phones or softphones), and Analog Telephone Adapter (ADA).
  • Provisioning VoIP software and applications

Step 1:

VoIP mainly uses 2 protocols, H.323 and SIP (Session Initiation Protocol) in order to establish connections between the VoIP server and VoIP phones. The server records IP addresses and other required information of the user.

Step 2:

When a call is made over the network, the server locates the recipient’s IP phone and secures a stable connection. The call is then routed to its destination.

Step 3:

The analog voice signal is then converted into digital data signals with the help of Analog to Digital Converter(ADC).

Step 4:

The digital data is then converted into data packets.

Step 5:

Codecs (encoders and decoders) are used to compress the audio data to enable efficient transmission.

Step 6:

The data packets are transmitted over the packet-switched networks using the Real-Time Transport Protocol (RTP) and User Datagram Protocol (UDP).

Step 7:

The recipient end collects the packets and rearranges them in order. The Digital to Analog Converter (DAC) then converts the digital signals back into the voice signals.

What are the Benefits of Cloud Telephony?

Pros and Cons of Cloud Telephony

Cloud telephony services are mainly used by businesses like call centers, remote and off-site companies, e-commerce businesses, payment processing companies, and so on. The advantages of cloud telephony for businesses are as follows:

1. Comparatively More Cost-Friendly

Cloud telephony is far more cost-saving than traditional telecommunication. Since cloud telephony requires less hardware infrastructure and less on-premise maintenance, the costs are greatly reduced in the setup.

Further, making domestic and international calls requires no separate business call plans but only a working laptop with a headset and a strong internet connection.

2. Highly Scalable

Cloud telephony doesn’t require an on-site infrastructure since all of its services are hosted through the cloud or a third-party service provider. Thus, all a business requires is any software that supports VoIP service.

A company can freely choose a low-cost subscription model based on its operational capacity and users. Cloud telephony allows businesses to easily add or remove phone lines and users across multiple locations without having to install additional infrastructure.

Further, the system updates are done automatically by the service providers. So, there are no delays or interruptions during expansions. Thus, dynamic adjustments across the world can be made effortlessly with minimal limitations.

3. Highly Secure

What would happen to your business if all your telecommunication hardwares got damaged due to overheating or say, natural disasters? How would you maintain your communications then?

With cloud telephony, you do not have to worry about such things. Cloud telephony is more dependable and less prone to unexpected disruptions that would impact day-to-day operations.

Cloud telephony allows you to always stay online and have a trustworthy backup in case of disasters. If one data center fails, then another takes over instantly.

Cloud telephony also uses encryption protocols such as TLS (Transport Layer Security) and SSL (Secure Sockets Layer) to encrypt data between a client and a server.

Multi-factor authentication (MFA) and Role-based access control (RBAC) ensure that only authorized personnel can access the cloud accounts and systems.

Since cloud telephony providers conduct regular security audits and testing, the vulnerabilities and oncoming attacks like Denial-of-service (DOS) attacks are detected early and dealt with effectively to provide smooth ongoing operations.

4. Multiple Flexible Features

While traditional phone services provide basic services such as voicemail, call forwarding, etc., cloud telephony provides additional features such as call recording, video-conferencing, Interactive voice response (IVR), virtual phone numbers, voicemail-to-email, real-time analytics, auto-attendant, and seamless CRM integration.

In addition to being scalable, cloud telephony can easily configure advanced call routing, call queues, and IVR menus and optimize call flows based on business location, hours, and customer needs.

Thus, its features like mobile accessibility, adaptability, quick deployment, and customizability make it a more flexible and attractive choice for businesses of all sizes.

5. Effective implementation

Cloud telephony enables integration and centralization of all business communications on a single platform. It can be easily integrated with various software and business tools, such as CRM systems, helpdesk software, etc., and middleware platforms like Integromat.

This efficient integration with systems and applications allows for seamless communication, call logging, and customer data management without any extra custom coding. 

Disadvantages of Cloud Telephony 

Now, let’s look at some of the disadvantages of cloud telephony.
