Contact center software, also referred to as CCaaS or contact center as a service, provides businesses with the capabilities necessary to run a cloud-hosted customer contact center. Founded on traditional, voice-based call center solutions, contact center software enables inbound queueing and routing, outbound dialing, call analytics, and workforce management. However, this type of software goes beyond [call center infrastructure](https://www.g2.com/categories/call-center-infrastructure-cci) to support digital interactions in multiple channels, such as SMS, email, and chat. Common features of the [best contact center software](https://learn.g2.com/best-contact-center-software) include automatic call distribution (ACD), interactive voice response (IVR), omnichannel support, and computer-telephony integrations (CTI).

Contact center software is commonly used by support teams to staff a help line or by sales teams to handle prospecting. These products integrate with [CRM software](https://www.g2.com/categories/crm) applications to access customer information and to update customer records with the post-action summaries. They will often integrate with [contact center workforce software](https://www.g2.com/categories/contact-center-workforce), [speech analytics software](https://www.g2.com/categories/speech-analytics), and [contact center quality assurance software](https://www.g2.com/categories/contact-center-quality-assurance) solutions if the product doesn’t provide that functionality natively. Contact center solutions may also integrate with or include features for unified communications, or [UCaaS](https://www.g2.com/categories/ucaas-platforms). Some businesses opt to use [virtual receptionist services](https://www.g2.com/categories/virtual-receptionist-services) in place of contact center software.

To qualify for inclusion in the Contact Center category, a product must:

- Offer a cloud-based contact center solution
- Distribute incoming calls and manage phone number assignment for outbound centers
- Provide the infrastructure for call management, placement, and monitoring
- Provide multiple channels (such as voice, SMS, email, chat) for call center representatives to leverage
- Include the following features: automatic call distributor, interactive voice response, queue management, and computer-telephony integrations
- Supply additional features that assist call center operations, such as speech analytics, workforce management, and quality assurance
- Integrate with CRM software or a company’s system of record
