Outbound call center: A guide

Upgrade your phone campaigns with outbound call center software.

A guide to the best outbound call center

Last updated November 21, 2023

In the not-too-distant past, customers had few choices when they needed to contact a company.

Today, customers can use chatbots, email, live chat, Zoom calls, social media, and more to contact brands. Yet, even today, most customers use the phone to resolve issues with a company.

But handling customer inquiries via phone introduces complications and costs. Fortunately, outbound call center software and outbound calling services help mitigate the expenses of setting up and administering phone support.

And, good software makes phone support more efficient with time-saving features like intelligent call routing.

Given its importance to your business, on this page we’ll provide you with an in-depth overview of outbound call center software. We’ll review the following topics:

What is an outbound call center?

Traditionally, an outbound call center was a room full of desks, phones, and computers occupied by agents. Today, outbound call centers can be virtual too.

In either case, though, an outbound call center is simply a group of agents making calls to clients or prospects on behalf of their business. Agents in outbound call centers are typically trying to make sales, raise funds, or do research. Though it’s less common, businesses may also set up an outbound call center to provide proactive customer service.

Why should you use an outbound call center?

You should consider an outbound call center if your business does any of the following:

  • Makes sales or sets sales appointments via telephone
  • Conducts research through telephone polls or interviews
  • Provides phone support for proactive customer service
  • Reaches out to existing customers for renewals

Of course, just because your business doesn’t do any of the above doesn’t mean a call center isn’t worth considering. Any activity that requires a high volume of outgoing calls could run smoother with an outbound call center.

Who uses outbound call center software?

Outbound call center software use is most common in companies in the healthcare, technology, financial services, retail, and e-commerce industries. That said, it’s not at all uncommon to find companies in a wide variety of industries that use call center software.

What do outbound call center services cover?

It’s not uncommon for organizations to outsource some or all of their outbound calling through third-party outbound call center services. Different outbound call centers companies vary but outbound calling services generally cover one or more of the following:

  • Lead generation
  • Appointment setting
  • Scheduled callbacks
  • Customer surveys
  • Telesales, upsales, and renewals
  • Customer retention
  • Competitive market research

If you decide to keep your outbound calling in-house, you’ll need an outbound call center solution that doesn’t get in your way. That means choosing a solution that provides (at a minimum) the features you need to get started.

Of course, more sophisticated solutions may have additional features but the fundamental ones to look for include:

CRM, help desk, and other integrations

Outbound calling agents need to know whatever they can about the people they’re calling to provide the best service. Previous order information, account details, and other contextual data enable agents to personalize their outreach. This is why tight integrations between your outbound call center software and your CRM and/or helpdesk become vital.

Fortunately, most outbound calling solutions do include some basic integrations. And through CTI, most solutions also integrate call data with your computer which makes tracking much easier. You’ll find, however, that the best outbound calling center software includes even more integrations that help make it easier for you to unify the outbound calling experience for your agents, managers, and customers.

Call tagging, recording and monitoring

As an outbound call center scales, managing agents becomes an exponentially larger job. And that’s where call tagging, recording, and monitoring come in handy.

Tagging helps you organize calls by agent, customer segment, time of day, or just about any other parameter you decide on. That way, if needed, you can easily look back into your call data and pull recordings to review for performance reviews, training sessions, or disciplinary action.

Call monitoring is also an indispensable feature for managers because it enables them to keep tabs on agents in real-time. This can be especially useful for new hires, who managers may need to provide assistance to if a call is going poorly.

Call center analytics and reporting

While call recordings enable managers and agents to review specific calls, call center analytics provides high level performance call center metrics. Managers can use call center analytics and reporting to set goals and monitor progress, evaluate performance, and root out potential problems. Among other things, call center analytics enable you to see things like average talk time, missed and declined calls, transfer rate, call abandonment rate, and average speed of answer.

Power dialers

If you’ve ever worked as or with an outbound calling agent, you know how much time can be squandered dialing. Not only do you have to manually punch numbers in, but you also end up wasting time dialing phone numbers that aren’t active or don’t answer. Power dialers eliminate this wasted time by dialing numbers automatically and connecting a live agent when a prospect actually picks up. Not all outbound call center software haves this feature, but it’s a game-changer for larger operations.

What are the key benefits of outbound call center software?

Improved service channel continuity

If your company is like most, you’re likely managing more than one service channel. And as service channels multiply, maintaining continuity in the customer experience gets more difficult. Fortunately, good outbound call center software improves your company’s ability to provide a unified customer experience.

That’s why it’s important to look for call center software that integrates well with your existing tools. The more unified your internal processes and tools are, the more unified the customer experience.

Faster and more effective outbound calling

Outbound call center software makes your outbound calling simultaneously faster and more effective. Features like automatic dialing and CRM integrations allow agents to focus on talking(not dialing) and it equips them with critical context about the customer. Outbound call centers also help managers do their jobs better with capabilities like availability-based call routing optimization.

Reporting and analytics facilitates learning

Most quality call center software options come with at least a basic level of reporting and analytics. This allows savvy call center managers and agents to set goals, track progress, and analyze performance. All that adds up to higher quality and faster learning as well as improved overall productivity. Using call center software, you can measure customer service metrics such as:

  • First Response Time
  • Call Volume Trends
  • Call Handle Time
  • First Call Resolution (FCR)
  • Quality of Recent Support
  • Average Wait Time

What is the difference between inbound and outbound contact centers?

The difference between inbound and outbound contact centers comes down to function. Inbound call centers receive calls while outbound call centers conduct calls. There’s also a third type of contact center, called a hybrid contact center, which receives and makes calls.

Here’s a quick look at inbound and outbound call center uses cases that help illustrate the difference between the two:

Outbound call center use cases

  • Generate and qualify leads via cold outreach.
  • Conduct market research to pinpoint customer preferences and analyze competitors.
  • Provide phone support for proactive customer service

Inbound call center use cases

  • Receive and respond to support calls from existing customers.
  • Process orders and payments and deal with payment issues.
  • Inquire with customers about upgrades and/or renewals

How to choose the right outbound call center software?

Choosing outbound call center software can be downright overwhelming. To make the process a little easier, focus on these three criteria when evaluating potential software.

Quality of fit with existing/future team and software

The most powerful software isn’t the one with the most sophisticated features. It’s the software that your team can use, learn about, and grow with. So while you certainly want to make sure any potential software has the basic features you need, beyond that it’s all about the fit with your team. If possible, take advantage of free trials so your agents and managers can get their hands on the software. Oftentimes, what looks like easy-to-use software feels clunky when it’s put into production.

In addition to evaluating the quality of fit with your current needs, consider how you might grow in the future. Perhaps you expect call volume to increase or you’d like to enable more advanced tracking capabilities in the future. Whatever the case may be, it’s important that the software you select can grow with your organization as your needs change.

Expected speed and quality of service vs. cost

As with most things, you generally get what you pay for when it comes to outbound call center software. But not all outbound calling teams can maximize the more advanced features offered by premium contact center software.

So it’s important to balance your needs with the cost of the service itself. Fortunately, most call center software is offered in different price tiers so you can start with the more affordable version and upgrade easily if you need more functionality.

Length of time-to-value (TTV)

One of the most important aspects of successfully implementing software of any kind is securing buy-in with your team and executives. That’s why it’s critical to choose outbound call center software that has a short length of time-to-value (TTV).

The shorter the TTV, the faster your new software will demonstrate its value to sales reps, service agents, managers, and executives who may be skeptical about the investment. And when solutions demonstrate real, tangible value to your stakeholders, it becomes much easier to secure buy-in where you need it.
