Once successfully created, users can configure the inbound route destination as "DISA" or IVR key event
as "DISA". When dialing into DISA, users will be prompted with password first. After entering the correct
password, a second dial tone will be heard for the users to dial out.
Firmware Version 1.0.2.5
Configure the permission level for DISA. The available permissions are
"Internal", "Local", "National" and "International" from the lowest level to
the highest level. The default setting is "Internal". If the user tries to dial
outbound calls after dialing into the DISA, the UCM6510 will compared the
DISA's permission level with the outbound route's privilege level. If the
DISA's permission level is higher than (or equal to) the outbound route's
privilege level, the call will be allowed to go through.
Configure the maximum amount of time the UCM6510 will wait before
hanging up if the user dials an incomplete or invalid number. The default
setting is 10 seconds.
Configure the maximum amount of time permitted between digits when the
user is typing the extension. The default setting is 5 seconds.
If enabled, during an active call, users can enter the UCM6510 hangup
feature code (*0 by default) to disconnect the call or hang up directly. A
new dial tone will be heard shortly for the user to make a new call. The
default setting is "No".
