Good morning all,
I just wanted to report that the link on the Asterisk website to the Asterisk Essentials course is indeed broken as of today and has been for a number of weeks. It redirects to an old article entitled “Asterisk 12 Part IV: The SIP Stack Of The Future”.
I was able to find the link to the Sangoma University via archive.org’s Wayback Machine. You can find it here → https://training.sangoma.com/
Just posting this to ensure that people can find the course.
