I'm hoping I'm missing something basic here.... I have the ringer set to notify for voicemails. If I have the button on top of the treo NOT on silence, I get notified of voicemails without problem (have it set to both tone and vibrate). But if I put the button on silence (vibrate), then I don't get a tone OR vibrate-- ie, no notification (except the mail icon does show up if I open the treo to the phone page).... There MUST be a way to set this so it only vibrates on voicemail notification?...thanks.
