Cloud contact center (CCaaS)

Contact center as a service (CCaaS) is a model where all contact center software – telephony, queues, chat, reporting, and AI tools – runs in the provider's cloud, and the company uses it over the internet. There are no servers to buy or maintain, and you can add or remove agent seats quickly.

Why it mattersLaunch without your own servers or big upfront spend, and add seats as the team grows.

Also called: contact center as a service, cloud contact center, cloud call center

Comparison

Cloud or your own servers

The cloud suits teams that need speed and don't have in-house server admins. Companies with strict data requirements, integrations with closed systems, or their own IT team choose their own servers. If a platform supports both, you can start in the cloud and move on-premises later without switching products.

How CONTACT.WORK handles it

The CONTACT.WORK cloud version runs in our data centers in the US and the UK and can be up and running in a day. The same complete system installs on the customer's servers, usually in 2-7 days, with every module from telephony to shift planning. Your systems connect through a general API and webhooks: calls, chats, customers, outbound campaigns, recordings, and reports.

Unlike many CCaaS vendors, we charge no per-agent subscription. There are no license fees: you pay for a support plan, plus hosting in the cloud. AI services – speech recognition and synthesis and the language model – are paid separately, or they run on your own hardware.
