Here is an example of how the wait(1) is problematic.
A company can have time conditions for various times of the day. When a caller calls the company they can hear 'good afternoon' which should immediately be followed by the IVR announcement.
As is the case currently, the caller will hear nothing between the time condition destination announcement and the IVR announcement. Although 1 second is not a long time period, the delay breaks what the company wants the caller to hear.
There should be a way to change the value of wait() imho.
