Market experience. Younger, smaller CPaaS vendors may be at risk of going out of business or being acquired by a larger company, which could disrupt the service.

User and developer community. A strong user community for the platform can help developers make the most of its offerings.

Network infrastructure reliability. Choose a vendor that provides consistent and reliable service.

What Distinguishes UCaaS From Cpaas?

UCaaS, on the other hand, is a complete platform that provides a wide range of communication features, such as phone service, video meetings, usage reporting, and call recording. It’s like a ready-made painting.

So, to put it simply, CPaaS is like a blank canvas that you can customize to fit your needs, while UCaaS gives you a complete picture that you can start using immediately.
