Flex contact center FAQs
Contact center software is the technology that allows you to manage interactions with customers across channels like email or phone calls. It often has an interactive voice response (IVR) system to route customers to the right resource, agent, or rep.
A contact center solution may integrate with other systems like customer relationship management (CRM) software so you can collect or process customer data. It can also support call recording and call transcriptions for quality assurance and performance tracking.
Some contact center software is cloud based. This makes your contact center functionality available over the internet and stores data in distributed data servers instead of hard drives, so you can access it virtually.
By nature, cloud contact centers avoid the rigidity of traditional solutions like on-premise contact center hardware. And you get much more flexibility to add the features and functionality you need for a custom experience, the ability to scale up or down, and make adjustments as needed.

A call center solution is software that enables you to support customers. While “call center” historically referred to phone-only support, the term is sometimes now used to refer to “contact center solution” broadly.
Call center solutions specifically let you handle inbound and outbound customer support calls. And they can function within contact center software, where you can handle all of the communication you have with customers across email, SMS, chat, WhatsApp, and other channels.
When choosing a solution, consider the following factors:
Features
Can it support the channels you need (SMS, email, call, chat, and other messaging services like WhatsApp and Facebook Messenger)?
Does it include call routing functionality?
Will it integrate with your CRM and other existing systems
Does it provide reporting to to track your team’s KPIs and view results through dashboards?
Does it support cloud-based calling?
Flexibility
Is it easy to add channels if you need to expand your communications options?
Is it possible to change functionality to keep up with the way your team works?
Cost
Does it fit your budget for contact center software?
What’s the pricing model (by seat or by hour)?
A call center offers customer support exclusively over the phone. A contact center solution enables you to provide support over multiple channels—phone, email, SMS, chat, and more—for a holistic and modern customer experience that adapts to customer needs. It gives businesses more ways to reach and support customers, ultimately providing a better experience.
Read more about the distinction between call centers vs. contact centers.
Inbound call center
Inbound call centers receive incoming phone calls from customers. They typically handle customer service requests, purchases or refunds, and product questions. Calls are often routed through an interactive voice response (IVR) system to determine the nature of the request before routing the caller to the an agent.
Outbound call center
An outbound call center makes calls to customers or sales leads. These types of contact centers typically focus on reaching out to a list of leads to make sales. Integrations with customer relationship management (CRM) software are particularly important so reps know who they’re talking to and can easily update customer data.
Learn more about the difference between inbound and outbound contact centers.
On-premise contact center
An on-premise contact center has software and hardware on-site. It’s the traditional model of contact center software that requires agents to be in an office to access the programs and phone lines. This type of call center is associated with higher security as well as higher costs and less flexibility.
Cloud-based content center
A cloud-based contact center is a virtual version of the on-premise alternative. Cloud contact center software can be accessed through the internet and it stores data in distributed data servers. It allows agents to login and access the software online, so they can work remotely. A cloud contact center can be set up quickly with little upfront investment and adapted easily through application program interfaces (APIs).
