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.
