CPaaS gives developers building blocks, voice calls, text messaging, and video, delivered as APIs they embed directly into their own software. Instead of buying a finished phone product, a team builds communication into its app.
Where UCaaS is a ready-to-use platform, CPaaS is the toolkit underneath. It powers things like appointment-reminder texts and in-app calling.
Frontdesk gives you a business number answered by an AI receptionist that picks up every call, qualifies the caller, books the appointment, and logs the whole conversation to your CRM.
