How does the Concept of Cloud Telephony Work?

Cloud Telephony Work

As with any other industry, the communication sector has been revolutionized by the rise of the “cloud,” thanks to the constant stream of new technologies that keeps all businesses on their toes. Before the advent of cloud telephony solutions, every business needed to hire a dedicated IT department to maintain the maze of wires and devices necessary for seamless internal and external communication.

With the advent of new technologies, these wires, computers, and programs quickly became obsolete. Cloud computing eliminates the need for on-site hardware, software, and IT staff. All cloud telephony infrastructure installation, upkeep, and updates are now handled by the service provider. Businesses need just an interface to connect to the phone system server to begin making use of these services.

Cloud Telephony: What Does that term Mean Exactly?

One definition of “cloud telephony” is a service model in which clients access and utilize telecommunications resources hosted by their service provider. Additionally, this cloud-based service provides a web-based user interface for its clientele.

Previously, difficulties such as the necessity for a new phone connection and the accompanying expenditures, as well as the time and effort needed in putting up the appropriate infrastructure, hindered the process of expanding or moving a company’s office. In contrast, with cloud telephony, businesses need only inform their service providers of any such change, and the rest is taken care of mechanically.

Cloud telephony offers your firm various additional perks. Let’s look at a few of them:

Spend less on Maintenance and Upkeep:

Savings in operational expenses typically range from 15 percent to 30 percent. Virtualizing the whole system reduces the need for resources, which in turn lowers the overall cost to the business. Smaller and medium-sized businesses are able to better afford adoption with the pay-as-you-go model.

Highly Dependable, Having a very High Uptime:

In case of a server failure, data centers often house several copies of the system. There is no downtime when a system fails since another system takes over instantly.

Easily Scalable:

No business maintains the same size and form over time; all businesses either grow or shrink. Taking use of cloud telephony services may help you meet the ever-evolving demand. The server may accommodate an arbitrary number of users and channels, which can be added or removed as necessary.

Always Current:

In the software industry, new developments are often released as methods to enhance productivity. Your service provider will maintain the software and hardware that powers your communication system, so you won’t even notice any changes. The primary benefit of cloud telephony is that it automates service upgrades, so you never have to spend extra time or effort making them.

How Does Cloud Telephony Function, Exactly?

Cloud telephony systems function similarly to traditional telephones but are hosted by the service provider and accessed over the internet.

A Hosted PBX in the cloud is the first point of contact for customers calling in. A PRI line (a telecommunication standard used on an ISDN to deliver voice, video, data, and other network services between the user and the network) connected to the telephone service via a PRI card facilitates this data transmission (PRI line is a telecommunication standard used on an ISDN to carry voice, video, data, and other network services between the user and the network).

Hosted PBX from the provider keeps track of all calls made and where they should be directed. Each incoming call to your firm will be routed to the most qualified agent according to the hosted PBX’s settings.

Both service providers and end users have the option of blocking certain numbers or blocking all numbers using PBX rules. The server then places a phone call between the customer and the most qualified agent based on the information provided.

Faster call transfers are possible since all agents are connected to the same hosted PBX.

The Benefits of Cloud Telephony for Businesses.

Cloud telephony services provide several advantages that make them the best corporate communication option, including but not limited to the following:

Mailbox Message

Messages sent through voicemail are archived digitally. When all agents are busy or unavailable, this feature comes in handy. As soon as an agent receives a voicemail, they play it and respond accordingly.

Telephonic Call-Forwarding

Thanks to this function, business owners or representatives may still answer calls even when they’re not physically at their desks. Using cloud services, you may redirect incoming phone calls to any number you like. Save a roster of call-forwarding numbers and route incoming calls there instantly. Forwarding does not affect the calling party.


With IVR, companies may have a pre-recorded greeting play when a customer phones. The phone is answered and transferred by a robot. There is no need to pay for a separate receptionist while using this feature.

Monitoring and Recording of Phone Calls

When a business is up and running, the next step is maintenance, which entails constant watch over all operational procedures. Call recording allows for the convenient storage and playback of both incoming and outgoing phone calls for future reference. Consumers and companies alike may benefit from this feature since it aids in protecting the integrity of conversations and transactions.

Accessibility Across Several Platforms

The best cloud computing services will offer a user interface where you may access all of these features. This interface may be used from a desktop computer or the web, giving users more options. The majority of service providers now provide agent-accessible software. Telephony records and makes them available to agents and supervisors through mobile apps.


By allowing for adaptable setup, cloud telephony services are beneficial. For optimal efficiency, integrate cloud telephony with your customer relationship management (CRM) system, industrial management software, or other applications.
