Callbox: Globally Most Reviewed BPO Agencies


Success is not achieved overnight. It takes time, experience, a lot of hard work, and help, in one way or another, from industry peers to get you to where and who you want to be; and, it’s no way a one-man band, but a synergy of individuals with different talents, knowledge, and skills.  

Callbox has just achieved another success – we are once again named as one of the most reviewed BPO companies in the world on The Manifest

The Manifest Most Reviewed BPO Companies badge

The Manifest is a B2B resource platform that helps vendors become more accessible to prospective client companies by creating rankings of the top performers in various industries, which work hand-in-hand with their awards program.

Our goal is to take our BPO service to the next higher level in 2023, and beyond.
