ASAI and Call Control

Third Party Relinquish Control

The adjunct uses this capability to terminate a Call Control association. The call itself is not affected by this capability.

Information Flow

The adjunct expects a response to its request. The ECS:

— Relinquishes control of the call if the request is valid

Third Party Relinquish Control Parameters

None for this capability.

ACK (Positive Acknowledgement) Parameters

No parameters are contained in the acknowledgement for this capability.

Denial (NAK) Cause

This request receives a NAK for a Switch-Classified call if the request is made while the call is being classified (CS0/98).

Protocol Error (NAK) Cause

None for this capability.

Considerations

After an adjunct has invoked Third Party Relinquish Control for a call, the same adjunct or another adjunct can take control of the same call by invoking the Third Party Take Control capability.

If this call is being monitored (Event Notification active), the adjunct continues to receive event reports over the event notification association.

This operation does not disconnect any parties from the call; ECS call processing continues for the duration of the call.
