How It Works?

Contact Defero Partners and speak with a Telephony Engineer. Defero Partners does not have sales persons on our staff; all customers will either talk to a Technical Support Specialist, Call Center Engineer or Certified Telecommunications Engineer.

Your assigned Certified Telecommunications Engineer will take the time to understand your communications needs and explain all the options available to you while using Defero’s Cloud-based Solutions.

Defero will create your solution on our development servers for testing and your approval.


We will launch your solution only when you are 100% satisfied. Once launched your support engineer will be in contact informing you of new products and services that might benefit your business. Unlike our competition, We include all solutions and services at no additional cost to you for as long as you use our services.
