This article is a must-read if you are considering switching to a cloud-based call center. It will provide you with all the information you need to make an informed decision.

What is a Call Center Solution?

A call center solution can also be termed call center software. The program will help organizations land significant calls, whether inbound or outbound. With this software, organizations can route these calls to the desired numbers, trigger the pre-recorded messages, record calls, gather customer information, and efficiently conduct various other actions. With the new generation of consumers expecting quick answers to calls and resolution to issues, the need for proper cloud call center software is becoming inevitable.

The best thing about a cloud-based call center solution is that you can integrate it with multiple channels like live chat, email, social media, and SMS messaging to make customer communication seamless.

Types of Call Centers

Call centers offer a wide range of services, and different call centers provide various services. It is crucial to understand which type of call center offers what service. 

Inbound Call Center

The Inbound call center provides incoming call services to companies. This service is helpful to existing customers, new customers, or even the staff of an organization. Companies can provide many services using this inbound calling feature, including order processing, help desk support, logistic tracking services, call addressing, emergency response, etc.

Outbound Call Center

Outbound calls are an effective and affordable way to reach prospective customers. You can get your representatives on the call with the leads and market your product or service to them. The common applications for outbound call centers are to expand the sales reach, product or service sales, EMI Reminder, etc.

Automated Call Centers

Automated call centers will help reduce call management costs with the help of computer-based systems. These computer-based systems will take care of many caller responsibilities. These centers just need an operator who will take care of the systems. The automated call center is used mainly for managing voice broadcasting, Interactive Voice Responders (IVRs), schedule reminders, etc.

Omnichannel Call Center

Customers love having a personalized experience. You can offer this using an omnichannel call center. These contact centers use all available channels to communicate with customers. With people expecting a customized and better experience, providing them with an omnichannel service is always a good idea.

What is an On-Premise Contact Center?

Also called legacy contact centers, on-premise contact centers will be operated in a particular business area alone. The companies must invest in hardware and software, which will be located in one place and must be operated from there. These contact centers are based on platforms provided by Avaya, Cisco, and Genesys. 

The on-premise contact centers are outdated technology and unsuitable for disruptive changes in customer behavior. The setup of an on-premise contact center takes 7-24 months, and any upgrade of systems will take 9-12 months. This impacts the overall performance of an organization. 

Difference between Cloud and On-premise Voice Services

The on-premise vs. cloud contact center debate proves that they have their own set of advantages and setbacks, including:


The hardware and software are deployed in an on-premise voice service on the client’s premises, and organizations should bear setup costs and have a team of experts available. However, the cloud has different setups – private, shared, hybrid, etc. All of these are preferable for businesses according to the requirement. Businesses should just pay and access these resources at any given time.


In an on-premise setup, the organization controls all the data. Due to this privacy concern, most highly regulated organizations hesitate to move to the cloud. Understanding who controls the data has always been a struggle in the cloud. Even vendors are troubled by this question. Although encryption and third-party keys are available, relying on them alone takes work.


The organizations are responsible for all the ongoing costs related to hardware, software, space, and power consumption. The cost has always been a significant drawback of on-premise setup. The businesses that opt for cloud telephony should spend money on the resources they use and nothing else. They don’t have to worry about maintenance or any other issues. The pricing can decrease or increase depending on the usage of resources.


Some businesses deal with extra-sensitive information and need high-end security. For such companies, an on-premise setup offers greater security than the cloud. Here, they have the entire data stored in their device, which any third party person cannot access without permission. The cloud-based call center setup has some security concerns, even with effective encryptions. Although IT people struggle to protect data, there still needs to be a guarantee of complete security in the cloud.


In an on-premise setup, scalability is in question. Adding extra devices, deploying software, etc., will consume much time and come at a heavy price. Scalability is a great advantage when it comes to the cloud. Businesses can just use extra resources and pay for it. The setup is so simple and efficient.

While discussing on-premise vs. cloud contact center, we should look at different functionalities that make cloud contact center a better choice.

Cloud Telephony

Everything is moving to the cloud lately, so why not your PBX system? Cloud telephony means hosting your PBX on the cloud itself. The service will be based on VoIP. Cloud telephony is a part of UCaaS (Unified Communications as a Service), a model that brings various collaboration tools and communication systems together. You can connect your phone system with other messaging services, video meetings, CRM, etc.

Cloud telephony works with the help of the Internet. Whenever you place a call, it is routed to the required number by your service provider. The analog signals are converted into digital packets, and then they are transmitted via your internet connection.

Cloud telephony provides many features like call forwarding, live call monitoring & whispering, call queueing, call conferencing, Interactive Voice Response system, sticky agents, call recording, analytics and reporting, API Integrations with different platforms, Blended Call Center, marketing initiatives like SMS marketing, etc.

Virtual Number

Virtual phone numbers aren’t limited to a fixed location. With this number, users can connect to anyone at any time with the help of VoIP. Users can deploy desk phones, softphones, mobile, etc., for communication. The virtual number acts as a mask for the original phone number, and businesses can use it to receive both inbound and outbound calls. They provide great anonymity despite looking like an actual number.

The virtual numbers don’t have any SIM or wired connection. They are provided by the operator in the cloud, and when a customer contacts this number, the call will land in the preexisting mobile/telephone number. Virtual phone numbers provide many benefits, including privacy, sync with preferred devices, affordability, etc.

Right now in India, there are four types of virtual phone numbers India available:

  1. Landline Number: Eight-digit number with an STD code as a prefix. This number is used for intra-organization communication. 
  2. Mobile Number: A ten-digit number that looks like a mobile number. Most of the field agents have this number to contact their customers.
  3. Toll-Free Number: A free calling number for customers. Businesses incur all the costs and attach the number to multiple channels.
  4. Local Number: Virtual local numbers with the STD code of the customer’s locality.
