ASAI and Call Control
Issue 7 May 1998
4-61
An acknowledgement (with party/extension information) is sent to the controlling
adjunct when the conference/transfer is complete. Included in the
acknowledgement is a list of all parties on the call (including extensions for local
parties).
The acknowledgment is sent over the association used to request Third Party
Merge. Any other associations monitoring the call or Domain Controlling
endpoints receive the Call Conference/Call Transferred Event Reports.
Denial (NAK) Cause
The ECS issues one of the following reasons as the cause for denying the
request:
■ Invalid association (CS0/81)
The association is nonexistent.
■ Invalid number/domain (CS0/28)
The controlling party has not been specified correctly.
1. The field “Send UCID to ASAI” is administered on the feature-related System
Parameters form.
result_call_id The call_id after the call is merged (provided by the
ECS).
party_id list The list of party_ids for the merged call (provided by the
ECS).
old party_id A list of party ids corresponding to the calls prior to the
conference. This report item is used in conjunction with
the party_id list to map the party ids prior to the
conference to the party ids after the conference.
extension list The list of extension numbers for the parties on the
merged call. Off-ECS parties always provide the default
station extension. The address for queued parties is the
split extension of the queue.
