Event Notification Capabilities

Event Notification Cancel

This capability enables the adjunct to cancel any notification request (for all calls) for a given domain only for the association that received the request.

Information Flow

ECS always accepts the request. If the request is not understood by ECS or is received over a non-Event Notification association, ECS aborts the association. See Chapter 3, ‘‘Event Reporting and U-Abort Capabilities’’ for more information regarding the U-Abort capability.

Event Notification Cancel Parameters

None for this capability.

ACK (Positive Acknowledgement) Parameters

No parameters are contained in the acknowledgement for this capability.

Denial (NAK) Cause

ECS issues the following reason as the cause for not executing the request.

Invalid association (CS0/81) The association does not exist.

Protocol Error (NAK) Cause

ECS issues the following cause for generating a protocol processing error:

Protocol error (CS0/111)

The Q.932 protocol has been violated.

NOTE:

For more information regarding protocol errors and a complete list of reason codes (cause values), see the DEFINITY Enterprise Communications Server CallVisor ASAI Protocol Reference, 555-230-221.

Considerations

The cancel notification takes effect immediately. Event reports to the adjunct for calls in progress cease over this particular association.
