So, now that you have witnessed one of the practical cases of the technology, you might be interested in digging deep. Our team of experts has also gathered some core functionality and benefits for you. Let’s have a quick read! 

How Does CPaaS Work?

CPaaS is a Communication API.

The Application Programming Interface (API) is a set of functionality that acts as a catalyst between two endpoints. For example, a device and software app, both these endpoints are allowed effective communication with the help of CPaaS. 

These APIs rely on Voice over IP (VoIP) to get data from one point to another. To make you understand the functionality, we have some examples mentioned below:-

  • Making a call by entering a phone number
  • Text message transmission
  • Requesting the status of an item you’re expecting to be delivered

Thus, to use CPaaS, you need an experienced team of developers for application customization. With apt tech brains, you will also need Software or a device that allows interaction with API endpoints. 

CPaaS solution offers the following cloud communication offerings.

  • Extensive documentation
  • Code samples
  • Coding libraries for web and mobile platforms
  • SDKs
  • Customer support

Ideally, you’ll see actual examples, code snippets, workflow descriptions, examples, and also a demonstration of the communication channel you want to use.

Key Functions of the CPaaS Platform

All these are the core functionalities of CPaaS, which you can implement at its best in your communication setup. And so, the platform allows adding multiple features, like voice, SMS, fax, etc., in one software.

Outbound voice calls

One can easily embed outgoing calls with the voice API. A user gets new phone numbers and calling features on an instant basis. And thus, the functionality of a voice API is ideal for adapting quickly to changing environments and increasing or decreasing the calling capacity.

Inbound call routing

Use call routing to simplify the processing of incoming calls. Webhooks are how it functions. When a call is received, a webhook is activated, and the system complies with a set of directives for what to do with the call. In contrast, platforms for inbound call centers offer all of this without the need for programming. To tailor and streamline how you handle incoming calls, you can include instructions that direct the call to a specific recipient. It is especially useful during the busiest times of the year.

WebRTC-based calling

The open framework enables real-time communication for the web. Many CPaaS software providers use WebRTC solutions as a part of their service. This functionality also allows you to easily embed voice and video communication in software. So, eventually, you will be integrating features like conferencing, recording, call queues, and more.  

Text messaging (SMS)

Through SMS communication, you can easily send notifications, alerts, and more, all from one business number. One can also create two-way messaging, send group messages, track them, and automate the workflow. 

On-demand SIP trunking

It provides connectivity to your IP-based communications infrastructure. SIP trunking is extremely flexible when you need an instant increase or decrease in call capacity. Also, many CPaaS providers provide such a service; choose one wisely.

Multimedia and video messaging

Many CPaaS platforms also allow MMS as a part of their communications service. Those who frequently do, give several options for sending and receiving MMS messages to and from overseas numbers. Moreover, they also contain the facility for media storage, file conversion, and file size.

Number masking

It is used to secure an individual’s number and communicate for a business call. For instance, an agent and a customer can connect over a call without revealing their phone numbers. It also protects a customer’s identity and ensures information safety and privacy. Only the CPaaS platform has access to all the users’ phone numbers.

After knowing its functionality and its overall communication effectively, how to choose the correct one is the debate. Here is a simple answer to it.

How to Choose the Correct CPaaS Platform for Your Business?
