@ing-joserivera26 seems like I’m having bad luck. My centos login PEM file seems crashed. So I decided to setup a fresh install of vitalpbx instead of fixing the pem file in recovery mode. But anyways, thanks , I’ll try your method if this happens again.
By the way, another question, is it available to setup multiple digits in IVR Menu? Such as 011042# -> recording
