Hello Asterisk Community,

Is there a way to check in asterisk cdrs and extension forwarded?

I mean, i'm calling to a ISDN number, wich goes to extension 8222, but
this extension is forwarded to another one, the problem is that in
CDRs i am able to see the the first step of the call, but never see
the forwarded extension, how can i do that?

Thanks!

The CDR is only going to record "all legs" on incoming calls. As you state
above, your "outgoing" call is going to show as "one leg" regardless of 
how
many "bounces" it takes.

The way I have addressed this issue is using flag variables that determine 
how the call has originated. Inbound calls set one state and outbounds 
calling checks for that state if it exists we assume that it is either a 
call forward or a transfer. We then check headers and variables to see what 
state it is. We then forward the outbound call through a call to 
LOCAL/customeroutbund/number~trackingvars. This will cause the system to 
create a sperate channel leg for that part of the call. We have found it to 
very tricky to get this right for both blind and attended transfers as well 
as call forwards but you can get very close. We were loosing on 100% of our 
transfers and forwards and now we are down to 3%-5% of the cases where our 
method does not work. Or 100% method is to use an additional asterisk box 
that routes all toll bearing inbound and outbound calls we disable forwards 
and transfers there. That is where we bill from so we don't loose and $$$. 
Asterisk 1.8 is looking good with the CEL logging but you have to sift the 
records to create billing CDR's
