This feature allows multiple ASAI route requests for the same call to be simultaneously active. The route requests can be over the same or over different ASAI links.

Route requests are all made from the same vector. The requests must be specified without intermediate wait-time, announcement, goto, or stop steps. If the adjunct routing link commands are not specified back-to-back, standard adjunct routing functionality applies and previous outstanding route requests are cancelled when an adjunct routing link vector step is executed.

The first route select response that is received by Communication Manager is used as the route for the call and all other outstanding route requests for the call are canceled.

With multiple outstanding route requests, multiple adjuncts can process the route call request without waiting for the first route attempt to fail. An application can make use of this feature to distribute the incoming call load evenly across adjuncts based on the adjunct’s current CPU load.
