Some incoming calls going straight to voicemail. I am getting frustrated with my iPhone 5. Some of my calls are going to straight to voicemail. I will have a voicemail come in with NO record of a call being made in the phone log and no ringing.It does not happen every time. have an iphone 5c & some calls went straight to voicemail, but not all. When you scroll up on your phone there is a shortcut to the flashlight, calculator,etc. I use this shortcut fairly often. Well, evidently I hit the do not disturb icon. When in this mode only calls from your favorite list will ring through.
A: A DSS - or decision support system - is designed to provide effective analysis relevant to specific situations while an MIS - management information system - is designed for the efficient processing of data or information. As such, they are generally used by different people in different situations.
In terms of applications, DCS is the system of choice for installations that are limited to a small locate, like a single factory or plant, while SCADA is preferred when the entire system is spread across a much larger geographic location,like a power station or oil wells which are spreaded out in a large field.
