If set to 0, the old ETI speech engine will not be run when an audio call is sent or received, and an instance of SAPIWrap will not be run.
If set to 1, the old ETI speech engine will be run when an audio call is sent or received, and an instance of SAPIWrap will be run.
Note: Use of the ETI speech engine with the call-out system is now obsolete. This variable has been added for backwards compatibility.
Default: UseOldSpeechEngine = 0
