This may be pretty simple, but I installed AsteriskNOW over a year ago. I've been running the "yum update" on a fairly regular basis. My current version of Asterisk is 11.17.1
I'd like to upgrade to 13. I've been searching online now for over an hour - how can I tell which version of AsteriskNOW I have? I've managed to upgrade FreePBX to 13, but I'd like to upgrade Asterisk as well.
I can see there are scripts to run, but I don't want to hose my system.
