i have 3 question on Voice Mail Port Wizard in CCM 5.x, specifically when using Voice Mail Port Wizard there are some config settings under Cisco Voice Mail Device Information like: CSS, AAR CSS, location
1: i still didn't get the idea behind these settings, how could this port between unity and CCM be used to dial numbers, so that I have to restrict it by assigning a CSS for it,
2: why and how to implement the locations for these ports if I have 32 ports between unity and CCM, i know
that the purpose of locations is to help WAN links from becoming oversubscribed,
but I still didn't get the idea behind assigning locations to these ports
3: finally what is meant by device and line in this VM port wizard, since there are settings per device and settings per line?
