Cloud calling’s ability to support these advancements makes it a vital component in modern communication strategies across industries. Let us understand what is cloud calling and why your business needs it.
What is Cloud Calling?
Cloud calling, also known as cloud telephony, is essentially a telephone service that operates through the cloud instead of a traditional phone line. The core technology relies on Voice over Internet Protocol (VoIP), allowing voice signals to be sent digitally via the internet. Reliable cloud calling providers host the required technology and infrastructure, so businesses don’t have to manage physical servers or equipment.
Cloud calling is part of a larger category called Unified Communications as a Service (UCaaS), which often includes various communication tools: messaging, video conferencing, data analytics, and more. For businesses, this means an all-in-one platform that supports seamless communication across teams and departments, no matter where they are.
How Does Cloud Calling Actually Work?
Cloud calling, also known as cloud telephony, uses internet technology to provide voice communication in a streamlined, efficient way. The process is sophisticated and involves several essential steps that convert, transmit, and reassemble voice data for seamless calling experiences.
Below is the detailed explanation:
1.) Analog-to-Digital Conversion
When a call is initiated, the first step is capturing the caller’s voice through the device’s microphone in an analog format. This analog voice signal needs to be digitized, and this is achieved through a process called analog-to-digital conversion (ADC). During ADC, the analog signal is sampled at regular intervals, with each sample converted into a digital value representing a precise point in the voice signal. This digitized data now represents the voice in a format suitable for internet transmission.
2.) Packet Switching
The digital voice data is then broken down into smaller units called packets. Each packet contains a part of the audio data along with crucial metadata, such as the source and destination addresses, sequence numbers, and timestamps. These packets are sent over the internet via the Internet Protocol (IP), which ensures that each packet reaches its destination accurately. The IP handles the routing of these packets across the network, maintaining data flow between caller and recipient.
3.) Network Routing
Once the packets are sent, they are processed by the cloud calling platform. Hosted on robust servers within data centers, this platform manages the packets, using advanced routing algorithms to ensure they reach the intended recipient. Depending on the nature of the call, this could involve routing to another internet-based device or to a traditional phone system connected to the Public Switched Telephone Network (PSTN). This layer of routing enables cloud calling to integrate both internet-based and traditional telecommunication systems seamlessly.
4.) Packet Assembly and Digital-to-Analog Conversion
Upon reaching the recipient’s end, the packets are reassembled in the original order by using the sequence numbers and timestamps attached to each packet. Once reassembled, the digital data undergoes digital-to-analog conversion (DAC) to transform it back into an analog format. This analog signal is then delivered to the device’s speaker or headset, where it is played back as audio, allowing the recipient to hear the caller’s voice as intended.
The whole process is incredibly efficient, with minimal delay or loss in quality. Reliable providers have networks that offer consistently high-quality audio, so conversations sound as clear as those on traditional phone networks.
Key Features of Cloud Calling
Cloud-based telephony offers many features that make managing calls and customer interactions simpler and more productive. Here are the standout features:
- Call Forwarding and Diverting: Forwarding allows calls to reach you or team members no matter the location, whether at home, on a mobile device, or at the office.
- Call Monitoring: Listen in on calls in real time or after the fact. Great for quality control and training purposes.
- Auto Attendant: Think of this as a virtual receptionist. Callers are directed to the correct person or department without human intervention, saving time and resources.
- Call Recording: Capture audio from calls for reference or compliance needs. Useful for quality assurance, legal record-keeping, and reviewing important details.
- Call Routing: This feature uses intelligent rules to route calls to the right department or person based on factors like time of day, language, or agent availability.
Cloud Telephony vs. Traditional Landline: What’s the Difference?
While traditional landlines have been the standard for decades, cloud telephony is rapidly gaining popularity due to its numerous advantages. Traditional landlines and PBX (Private Branch Exchange) systems require on-premises hardware and complex setups, whereas cloud calling is hosted entirely online. Here’s how they compare:
| Feature | Traditional Landline | Cloud Telephony |
|---|---|---|
| Infrastructure | On-premises hardware (PBX, phone sets, wiring) | Cloud-based, no on-premises hardware |
| Setup | Complex installation and configuration | Simple setup and configuration via web portal |
| Cost | High upfront costs, ongoing maintenance | Lower upfront costs, pay-as-you-go model |
| Flexibility | Limited to physical locations | Access from anywhere with an internet connection |
| Scalability | Difficult to scale, requires significant investment | Easily scalable with minimal investment |
| Features | Basic features like call forwarding, voicemail | Advanced features like call recording, IVR, call analytics, video conferencing |
| Security | Vulnerable to physical security threats | Enhanced security measures like encryption and firewalls |
Cloud-based calling essentially gives you the power of an entire communication system without the headaches of managing or maintaining it.
Benefits of Cloud Calling
Switching to a cloud calling environment brings a wealth of advantages, with the most notable being the potential for substantial cost savings. Instead of investing heavily in an on-premise phone system, organizations can leverage cloud technology to access a flexible and scalable phone solution. This approach eliminates the expenses and complexities tied to provisioning, configuration, upgrades, and ongoing security, making it a far more economical choice.
Here are the several other compelling benefits to consider with a cloud phone system:
