Some have instructions, some have users you could reach out to via thread to get details on their successes.

but will it work for Asterisk 13/freepbx 14

Try it? Report back. If it works, you’ve made it easier for the next person looking for information. If it doesn’t work, others know what you’ve tried so they avoid rehashing what doesn’t work.

should i backup my system first

Having a backup copy never hurts

You meant “I should backup my system first”, right? :slight_smile:
