ASAI and Domain Control
Third Party Domain (Station) Control
Request
An adjunct uses this capability to receive event reports and control calls at a specified extension.
Information Flow
The adjunct expects a response to its request.
The ECS returns an acknowledgement to the application after the ECS verifies that the station number is valid and the maximum number of controllers for the station has not been reached.

ACK (Positive Acknowledgement) Parameters
The ECS responds to the adjunct’s request with a list of call_ids, the party_id of the principal’s extension on the call, and the state of the principal’s extension on the call.
Denial (NAK) Causes

■Invalid number/domain (CS0/28)
An invalid address or extension number is present in the request.
■Service or Option Not Available (CS3/63)
The maximum number of Domain Control Requests are in use for the domain.
■Switching Equipment Congestion (CS0/42)
The ECS is not accepting the request at this time because of processor overload. The adjunct or user may wish to retry the request but should not do so immediately.
