Asterisk PBX in 2026 — Still Relevant?

What companies still use Asterisk, and how are you using it today?

I used to work in tech support at my previous job, where we supported VoIP systems using Asterisk. I’m curious if ISPs or other industries are still actively using it.

If you’re currently working with Asterisk, what’s your experience been like? What type of company do you use it in, and for what use cases?

Thanks!
