I am at a complete loss. I have searched for a while now and I cannot get a mailbox to work.

CentOs 6.7 asterisk 1.8.32 freePBX

I did this installation through the wiki.freepbx http://wiki.freepbx.org/display/FOP/Installing+FreePBX+12+on+CentOS+6.5 in voicemail admin it says my mailbox are 'unactivated'

in asterisk CLI when I try *97 softphone hangs up but CLI provides these errors

The line "Syntax IF(?[][:]) (ex" suggests your dialplan was not properly constructed by FreePBX. Either you have severely misconfigured (or under configured) FreePBX, or you have some form of corruption on your system.

  • thanks for the feedback. Any Tshooting ideas? I'd rather not go through a re-install...
