Just to add For example asipto developers have written a handbook/setup guide for beginners (explaining everything step by step) how to install and manage Kamailio..and they charge something like 50Euros..I mean it’s a great idea for a starter..if 2600hz ever did that I would be the first to purchase it..
As a user I wouldn’t even mind contributing to it for something like that, I’m sure it would be very helpful for people who are just starting up
