E. How to choose a call center phone software?

Choosing a call center phone system can be a complex and time-consuming process, as there are many different options available, each with their own unique features and capabilities. Here are some key considerations to take into account when choosing a call center phone system:

1. Business Needs

 The first step in choosing a call center phone system is to identify the specific needs of your business. Consider factors such as the volume of calls you expect to handle, the types of calls you will receive, and the number of agents or representatives you will need to support.

2. Features

 Consider the specific features you require, such as automatic call distribution, call routing, voicemail, and caller ID. Also consider advanced features such as call recording, call scripting, and real-time analytics, which can be used to improve the efficiency and effectiveness of customer service operations.

3. Scalability of a call center software

Choose a call center phone system that is easily scalable to accommodate future growth or changes in your business.

4. Integration

Consider how well the call center phone system can be integrated with other existing systems, speech analytics software and applications, such as CRM, helpdesk, and business intelligence software.

5. Provider

Consider the reputation and experience of the provider, their customer support and their technical expertise.

6. Cost

 It is important to consider the cost of the call center phone system, including the initial cost, ongoing costs, and any additional costs for additional features or support.

7. Remote working

With the growth of technology and the present global scenario, many organisations are shifting to a remote working model; consider a call center phone system that allows your workers to work remotely.

8. Security

As the call center phone system will be handling sensitive customer data, it is important to ensure that the system has adequate security measures in place to protect this data.

F. 8 Standard Call Center Software Features

Infographics of 8 Standard Call Center Software Features

There are some standard call center software features you should look for when selecting the software.

These functions will save you time and keep your frustration level down.

As well as saving time, these features will also ensure that your agents respond professionally to calls.

A well-developed call center system will have many standard features, including:

1. Cloud-Based Calling

A lot of call centers today are using cloud-based management systems.

These allow users to complete various tasks, such as making outbound calls from their desks or tracking the time they spend on the phone and other activities.

Other people may want to record all important calls for future reference or streamline inbound calls with an IVR system.

This is made easier with a cloud-based solution since there’s no need to install extra hardware like VoIP boxes.

For all those who don’t understand what cloud-based calling is, it is a phone or telephone service that operates over the internet using the same Voice over Internet Protocol (VoIP) technology.

A cloud-based service typically has its own server that your company pays to use instead of paying a third-party provider.

This can be much cheaper than leasing landlines and phones from a telecommunications provider.

2. Omnichannel

At the end of the day, any BPO wants to standardize its call center technology, software upselling & enterprise CRM to deal with single-core processes rather than multiple and doesn’t want to take the pain of updating them from time to time.

It also offers an integrated or single-user experience for its customer, which will provide a client migration experience that is smooth and seamless.

Omnichannel support means that you can support customers the same way whether they’re talking to you by phone, email, live chat, or social media.

If your call center software can’t integrate with other channels (like LiveChat, for example), then it’s not omnichannel.

3. Call Routing

Routing calls can be complicated, and it’s easy to get caught up in the complexity and lose a sense of how it will actually work on the phone.

All businesses who rely on having clients via the phone will probably need call routing software Features.

Lots of companies have used various types of automated call distribution and call management to handle their client calling requirements.

While choosing a call center solution, you need to take into account several factors such as the system’s ability to connect calls inbound, outbound, and among multiple call center users; ability to route a call based on the caller’s record, business rules, time of day or day of the week.

All though it’s one of the most important features of the call center phone system.

4. Call barging

Call barging is a standard call center feature that enables or automates the transfer of calls between agents.

The call could be transferred to the agent handling the most calls or one with the least number of calls.

Call barging is an essential part of many software call tracking solutions or rota-based call system architectures.

If your customer service software doesn’t provide call barging options, then read the next section in this article on what features you should look for in your call tracking solution.

5. CRM Integration for Customer Context

There is no doubt about the importance of the CRM tool in the call center phone system.

It helps in creating a centralized database that can access all customer information and data.

A CRM provides your company with up-to-the-minute customer information across all departments and enables you to coordinate sales and support staff effectively.

With integrated CRM, your cms and voicemail system work together, delivering customer information to agents in real-time – it’s amazing how seamless this can make operations run.

6. Reporting

There are so many features available that are not really needed, and on the opposite end of the spectrum, features that could help you save significant money and time.

One of those features can be reporting-related. Reporting is one of the important features of standard call center software.

Caller reports allow you to see how long a call lasted, who spoke, what was said, and many more statistics.

You can easily export this data into a spreadsheet and use it for analysis.

All the other types of call reports can be used for training purposes.

Even though the report user interface is simple, all the necessary information is clearly displayed, and there are even call diagrams in some programs.

7. Usage Pricing

One of the first things you should do is take a close look at the software’s pricing per Agent/phone call or peruse.

Depending on how your chosen software assigns your phone numbers, you might be charged more than expected for each minute on the phone.

Before committing to any new phone lines, confirm what’s included in the package and how much each call and minute will cost.

8. Interactive Voice Response

Interactive voice response (IVR) is a key element of any modern call center software system.

Interactive Voice Response services are there to aid users in completing their tasks, and they give you the possibility to smoothly run customer interaction within your company.

If you have a call center or a customer service department, you will definitely need an IVR service to boost up your efficiency.

You won’t always be able to provide your customers with a perfect service right away since it will take time. Still, modern technology can provide the best solutions for both supporting your customers and improving your business overall.


Choosing the right Call Center Phone System is certainly not a decision that should be made hastily.

Such a decision should be based on your needs and also on the quality of services that will be offered by the provider. 

Now that you have all the information about the best call center phone systems out there in the market, you can make a better decision.
