ASAI and Call Control
Third Party Make Call
The adjunct uses this initiating capability to establish a call between two parties.
Information Flow
An acknowledgment (ACK) is optional for the Third Party Make Call capability. If requested, an ACK is sent to the adjunct when the ECS successfully originates the call (a call identifier has been assigned). If conditions prohibit a call from being established, a Negative Acknowledgment (NAK) is returned.
Starting with Release 6, if the UCID (Universal Call ID) is present, it is included in the acknowledgment if administered to be sent. An application that wishes to make use of the UCID should request an acknowledgment since the UCID is not included in every event report.
Third Party Make Call Parameters
orig_addr [mandatory] The calling station’s address. For
dest_addr [mandatory] The called party’s address.
dest_route_ [optional] The trunk access code or feature access code [for
selectexample, Automatic Route Selection (ARS), or Automatic Alternate Routing (AAR)] of a called endpoint that is not directly connected. Alternately, this information may be included in the dest_addr.
return_ack [optional] If this parameter is present, it indicates that the ECS should return an acknowledgement to the request. If this parameter is not present, then the ECS does not return an acknowledgement.
