This site was originally started as a place to store information about how to disable a SIP ALG on various brands of routers. This was due to my previous employer not having a public knowledge base, and I needed an easy way to point customers to a link with images.

Over a period of years, the site transformed into more technical information targeted at IT Administrators, Network Engineers, and those interested in learn more about VOIP and related technologies.

Eventually, I published a Course on Udemy about the SIP Protocol.

The Fundamentals of SIP
