So it appears that from our AA you can only direct dial extensions that have a VM setup. For instance if you dial 145 Server Room (no VM) from the AA you get "you have entered an invalid phone number" But if you dial 116 Bob Smith (has VM) you get put through no problem. Yes "Dial by number anytime" is checked in the AA settings. I can't imagine that you would need to have voicemail enabled to be dialed directly from the AA. Thoughts?
