About

I started this website due to the demand for SIP training. I realized that while other companies offer SIP training it’s a difficult expense to justify for someone starting their career in the VOIP world.

 

Why should I take this course from you?

I am a Senior Engineer that works in the Service Provider space. The networks I manage consist of over 200,000 users. My focus is on the core call processing architecture and signaling systems between multiple carriers.

While we do not offer a SIP certification, we offer a unique way to start your VOIP career.

Keith Croxford is an expert in VOIP.

What else can I learn from this site?

I create content that describes how to resolve common VOIP issues. Many VOIP issues are due to features enabled on routers and firewalls. I will teach you to disabled these problematic “features”.

I look forward to teaching you about SIP and VOIP.
