Best Call Center Service Reviews

Nextiva – Best Overall

Nextiva company logo

One of the drawbacks of fully outsourcing your call center is being in the dark about the people handling your callers. It’s no good if you’re getting poor feedback from customers and you don’t have the means to train current staff to improve or replace poor performers with new hires.

Nextiva offers you an in-between solution that still delivers savings.

Nextiva’s call center software allows you to run it entirely from the cloud. That means you can have a fully distributed network of independent contractors manning your call center phones from any location.

Yes, you’ll still pay for some labor, but there’s no need to outfit a wing of your building with a full PBX phone system and the expenses that come with that. With Nextiva, you’re saving money while still maintaining full control over your call center and the people fielding calls.

Nextiva’s call center software runs on its Nextiva One platform. That may sound like a big investment in itself, but it’s not. There’s no need to install new equipment. Since it is a VoIP solution, Nextiva implementation is a snap.

Plus, it’s altogether affordable. Nextiva’s pricing is as follows:

  • Essential – $21.95 per month/user
  • Professional – $25.95 per month/user
  • Enterprise – $35.95 per month/user

Get the best of both worlds—keep control of your call center workers while still saving money by letting them work from anywhere (including their own mobile phone) with Nextiva.

SAS – Best Outsourced Call Center Answering Services

SAS stands for Specialty Answering Service. As the name clearly implies, the SAS call center’s primary focus is on being an answering service.

In addition to answering services, SAS provides call center outsourcing, dedicated call centers, lead generation services, and virtual receptionists.

SAS has bilingual receptionists and virtual office capabilities for their live operators.

The answering service is very diverse. While it’s obviously geared toward businesses, many people use SAS for personal use. Entrepreneurs, business owners, and busy professionals rely on SAS as a personal receptionist.

SAS has dispatching services with operators that answer calls in three rings or less. You can also get toll-free numbers, emergency answering services, and support on international calls.

Unlike most call center services, SAS has simple and straightforward pricing listed on its website. Here’s a quick overview of those plans and prices:

  • Economy — $38 per month + $1.39 per minute
  • 100 minutes — $139per month + $1.29 per additional minute

Signius – Best for Low-Volume Calls

Signius is a call center service that is 100% US-based. They work with small businesses, Fortune 500s, and everyone in between.

For us, the small business call center and answering services from Signius stand out the most.

As a small business owner, you likely won’t need a full call center of agents on-site handling phone calls 24/7. That’s obviously not an effective use of your resources. But Signius is available 24/7 and can answer calls even when your store is closed.

Signius has call transfer services, customized scripts, and bi-lingual solutions. Even if you don’t get a high volume of calls, this will be an excellent option for you to choose.

How to Choose the Best Call Center Service For Your Business

Reviewing the top call center services on the market today is a good start. But how do you choose the right one for your business?

There are certain factors you should take into consideration when evaluating a prospective service. This is the methodology we recommend and use at Quick Sprout.

Use these criteria to narrow down your options.

Variety of Services

Most call center services do much more than just answer phone calls. They usually offer a wide range of other services for things like market research, lead generation, event registration, and call forwarding.

What does your company need help with?

If you’re a small business owner that wants your customers to speak to a live agent instead of an answering machine when they call after hours, you can get by with just an answering service.

But if you’re a larger organization that needs outbound calls for things like lead qualification, sales, payment reminders, or membership renewals, you’ll need a company that offers these extra functions.

Availability and Call Center Locations

The best call center services have live agents available 24/7/365. I wouldn’t consider a call center service that doesn’t offer this.

In addition to consistent availability, it’s essential there are enough agents to quickly answer inbound phone calls. Consider only working with larger services that have multiple locations and plenty of staff on hand.

If a US-based call center is important to you, there are plenty of great choices to consider. You don’t have to outsource your call center overseas if you don’t want to.


Your call center is an extension of your business. While the live agents making and receiving calls don’t work directly for your company, they are the face of your business to customers when they call.

It’s important to find a call center service that has experience working in your industry.

For example, a B2B company that is using an outbound call center service for event registrations and a doctor’s office using an answering service for post-discharge patients will have very different needs.

Custom Solutions

As consumers, we’ve all experienced phone support where the agent is clearly using a generic script. Those canned responses are applied to every business, regardless of industry or customer need.

It’s frustrating when this happens. You don’t want your customers to have this same experience.

That’s why you need to find a call center service that will take the time to understand your business and its needs. They’ll help you come up with a custom solution to improve the customer experience via phone support.

For further personalization for your customers, some call centers offer dedicated agent services. This means that you will have a few agents who have special training to answer questions specific to your business. 

If you need to provide things like technical support for your customers, you may be able to hire a call center that will specialize in helping with these customer queries. 

Some call centers may even give you custom overflow capabilities. If all your own salespeople are on the phone, one customized service of the call center may be to take overflow calls as needed.

The pricing structure for most answering services will be completely customized as well. Make sure you understand how you’re being charged before you commit to a contract. In many cases, it’s the most cost-effective to be billed based on usage.

The Top Call Center Services in Summary

Traditional call center services help with a variety of tasks, including recording incoming calls, taking messages for team members, and responding to customer queries based on your company script. Many businesses prefer using the service to enhance their lead generation and lead marketing campaigns.

Nextiva is hands down the superior call center solution, but you can always opt for other solid solutions we’ve reviewed above. In the end, it all boils down to your specific requirements, budget, and locations.
