[cisco-voip] ipcc QUESTION re initializing callContact

[Joanne Thompson]

I am reviewing a script developed by somebody not with our company
anymore. Can anybody explain why the below would be done? This is logic
handling sending a caller to voicemail. 

1 - set some session information (understand this!) 
2 - set a _contact = ********

 (this is defined as a contact variable - value null - I am not sure how
this gets set to ******* - when i go into the expression editor i cannot
modify it) 
3 - if (_contact != null) then 
true - 
set enterprise call info (_contact) 
false - do nothing 
4 - Call redirect(triggering contact--to VM Number) 

What is the purpose of doing step 2 and 3?? As step 4 does not use the
_contact variable?
