Missed telephone calls aren't going to voicemail. It worked a couple weeks ago. Whats up with that?
If calls aren't going to voicemail, ensure your "call forwarding to voicemail" is set up.
1. Pick up the handset.
2. Dial *63777
3. Hang up.
*6 is system code for "forward," and 3777 is the voicemail extension. So *63777 forwards unanswered calls to voicemail.
Sometimes, people will inadvertently cancel "forward to voicemail." Then, they aren't receiving voicemail. #6 cancels the "forward" command, sometimes fat-fingered on accident.
