3CX Certified Engineer

The  process for VoIP providers to become certified 3CX engineers is in-depth and goes far beyond simple call in/ call out tests.

3CX is a diverse and feature rich phone system with many aspects to understand from deployment to maintenance.

VoIP providers supplying end customers with 3CX having a detailed understanding of the phone system ensures that businesses making the change to VoIP, or to a new IP PBX, are able to make the most out of it.

3CX Certification Levels

There are three levels of 3CX certification – basic, intermediate and advanced.

3CX Basic Certification
Intermediate 3CX Certification
3CX Advanced Certification

Part of the certification process for 3CX partners includes a strategic review of the providers’ services. Free versions of 3CX are available for testing, as well as in-depth test plans for prospective partners to ensure their services are fully compatible.

Partners are also required to retest their services with 3CX each time major changes are made to their services.

The road to becoming a 3CX partner is a long one and requires a lot of preparation. However, this is of great benefit to the end customers, and there is a substantial amount of documentation and support from 3CX through this process.

The 3CX certification process covers the following areas:
