Different type of Hunting Group under Avaya Communication Manager (CM)

DDC - Direct Department Calling (DDC) is also known as "hot seat" distribution. The system starts with the first extension in the hunt group, and hunts for an available extension. If the first extension is busy, the system checks the second extension. If the second extension is busy, the system checks the third extension, and so on.  When an extension is available, the system rings that extension to connect the call. This type of hunting provides the most equitable distribution of calls. Also, this type of hunting is required for a modem pool, data-line circuit ports, and data modules.
When the group is administered as a skill, DDC is unavailable

EAD-LOA - The system hunts for the available agent
who has the highest skill level, and the

EAD-MIA - The system hunts for the available agent
who has the highest skill level, and the
longest idle time since the last call. (Requires EAS)

available agents based on a comparison of
work time in the skill, and the target
allocation for the skill.

UCD-LOA - The system hunts for the agent with the
lowest percentage of work time since the
