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
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).
call_id [mandatory] Identifies the call to be reconnected
