General Features
• UCD Call Waiting
This feature is different from regular Call Waiting. This feature (if enabled)
allows UCD group members to hear a Call Waiting tone when an outside /
inside call arrives but all the extensions in the UCD Group are busy.
However, if a single extension belongs to multiple different Incoming Groups
and there are calls in the waiting queue in one of the Incoming Groups, the Call
Waiting tone is generated at the busy extensions.
The tone stops only when there are no calls in the waiting queue in all of the
groups.
• All Logout
All extensions in the Extension Group or Incoming Group can be logged-out.
This is determined by System Programming <Section 2.8 System Option,
"Empty Group" in the Programming Guide>.
If this feature is disabled by System Programming, the extension user cannot
leave the group (Log-Out).
At least one extension must be logged in.
However, this does not apply to Auto-Logout of the UCD group extensions.
• Call Log, Incoming
If a CO call to a UCD Group is not answered, the caller's information is
recorded in the Call Log of the last extension at which the call rang.
