ASAI and Call Control
This chapter describes the Call Control Capability Group.
1
 The capabilities in this 
group are categorized by their functions: initiating, controlling, and terminating. 
The adjunct uses these capabilities to set up (place), take control of, monitor, or 
end a call on DEFINITY ECS.
 
1.
Capability groups are analogous to the Application Service Elements (ASEs) described in the 
Adjunct/Switch Application Interface (ASAI) Specification.
This initiating capability enables the adjunct to set up a call 
on behalf of an on-ECS station. The four types of controlled 
calls supported by this capability are as follows:
Switch-Classified
User-Classified (with or without priority)
Direct-agent
Supervisor-assist
This initiating capability enables the adjunct to take control of 
a call that is already in progress to perform additional call 
control functions when needed.
This controlling capability enables the adjunct to place the 
controlled call on hold at the specified station.
This controlling capability enables the adjunct to direct the 
ECS to reconnect a specified station to the controlled call.
