I'd like callers to be able to call my 2nd line # directly and receive a unique voice message if unavailable. I created a personal device in Phone Number Preferences and assigned the handset the 2nd line #. When prompted on the handset, I recorded a unique greeting for that #/device. When I tested the voice mail from one of my Panasonic handsets, the voice mail recording was operational. When I tested it from my cell phone and from a remote land-line, it rang, connected, and an audible beep was heard seconds later...no message heard, no opportunity to leave a message.
What am I missing? HELP!
