asterisk users - May 2007 - Blind Transfer - Who transferred the call?

Hi all,

Is there a way to tell which extension transferred a call in a blind 
transfer?

Sorry if it's a basic question, but I haven't seen an answer. 
${CALLERID(num)} still holds the outside party caller id (which it 
should), but I'd like to the extension number of the extension that 
transferred the call.

Any suggestions?

Thank you,

Parsing the variable ${BLINDTRANSFER} gives what I need.

// Sample: AChannel = 'SIP/111-0Asswwosee'
Function DialStringFromChannel(const AChannel: string): string;
var
iPOS: Integer;
begin
    iPOS := POS('-', AChannel);
    if (iPOS = 0) then exit;
    result := Copy(AChannel, 1, iPOS -1);
end;


I had thought that there was a specific variable somewhere for the 
extension that transferred a call.  No matter, the above code works like 
a treat.
