Call Vectoring provides a vector disconnect timer, which can be set for a time between 1 and 240 minutes, inclusive. Set Vector Disconnect Timer on the Feature-Related System-Parameters screen to y. The timer starts when vector processing starts. Once the timer runs out, the call is dropped. The timer stops when vector processing terminates.

When you set the field to y, queued calls that have are unanswered within the administered time are dropped.
