A phone
has a device CSS that includes the partitions phones and PSTN. This provides
access
for all
internal phones and external calls. The first line on this phone has a CSS that
includes the
partitions
phones, 911, and local. If a call is placed to a long-distance number, will the
call be
completed
and why or why not?
Yes, because the call will use the device CSS
When
creating your own CSV file to be used by Cisco Unified Communications Manager
BAT,
which three
rules do you need to follow?
1. Edit the
Excel macro for each separate Unified Communications Manager BAT transaction.
2. Use a
separate line for each data record.

phone will go through the list from first server to last server listed in the
Cisco Unified
Communications
Manager group list.
