[Spce-user] Method to identify in CDR what answered a call (...to permanent contact or call forward rule)

[Gavin Sweet]

Hi all - 

 

I'd like to identify in the CDR where a successful inbound call
(call/200/ok) went when answered - whether to an actual perm contact, or via
a forward ruleset by cfu/b/t/na.

 

Specifically, I want to levy a different charge if the call was really
answered, versus if it went to voicemail.

 

I wondered whether there was an obvious and workable method someone has
tried to extend the call types/codes or destinations to add this
information?

 

Thanks, 

Gavin
