Operation
The purpose of the reply-best step is to return data for the best resource found by the consider series in a status poll vector to the primary vector in a multisite BSR application. The status poll vector executes in response to a call from a consider step in the primary vector. Each time the status poll vector executes, the reply-best step:
Drops the incoming call without returning answer supervision.
Returns status data to the primary vector using the ISDN DISCONNECT message.
Clears the best data.
Terminates processing in the status poll vector.
If the incoming call is not a trunk call, the reply-best command drops the call and logs a vector event. No status data is returned to the origin Communication Manager.
If the consider series yields no best data, the reply-best command drops the incoming call without returning answer supervision, terminates vector processing, and returns an infinite value for Expected Wait Time (EWT) in the DISCONNECT message. A consider series does not always produce best data due to any of the following reasons:
All resources being checked are unstaffed.
No resource being checked has an open queue slot.
The best data is cleared before execution of the reply-best step, which can be because there are no consider steps in the status poll vector or because the vector contains a prior step that clears best data.
