ASAI and Domain Control

Third Party Reconnect

The adjunct uses this controlling capability to reconnect a held call to a station.

Information Flow

The adjunct expects a response to its request.

The ECS either:

Reconnects the call after validating the parameters, or

Denies the request if the call_id parameter is incorrect

Third Party Reconnect Parameters

call_id

[mandatory] Identifies the call to be reconnected

ACK (Positive Acknowledgement) Parameters

No parameters are contained in the acknowledgement for this capability.

Denial (NAK) Causes

The ECS issues one of the following reasons as the cause for ending the association:

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

Invalid number/domain (CS0/28) The call_id is incorrect or invalid.

Invalid state (CS0/98)

The call is not currently in the hold state so it cannot be reconnected.

Mandatory Information Element missing (CS0/96) The call_id is missing in the request.

Resources not available (CS3/43)

The call cannot be reconnected due to too many parties on the call or other ECS-specific resource problems.

No User Responding (CS0/18)

The party was on-hook when the request was made and it did not go off-hook within five seconds (call remains held).
