[Asterisk-Dev] unique cdr id per call

[asterisk at billheckel.com]

CDR as offered is weak, no easy way to tell who hung up, doing a call abandonment report seems close 
to impossible and I need to link the calls in CDR with the calls processed by my ACD application. 
Adding a unique call identifier that is in the channel vars and the CDR record and exists from the 
beginning of the call through its completion would help.
