+If the channel has a cdr, that cdr record has it's own set of variables which 
+can be accessed just like channel variables. The following builtin variables
+are available.
+
+${CDR(clid)}			Caller ID
+${CDR(src)}			Source 
+${CDR(dst)}			Destination
+${CDR(dcontext)}		Destination context
+${CDR(channel)}			Channel name
+${CDR(dstchannel)}		Destination channel
+${CDR(lastapp)}			Last app executed
+${CDR(lastdata)}		Last app's arguments
+${CDR(start)}			Time the call started.
+${CDR(answer)}			Time the call was answered.
+${CDR(end)}			Time the call ended.
+${CDR(duration)}		Duration of the call.
+${CDR(billsec)}			Duration of the call once it was answered.
+${CDR(disposition)}		ANSWERED, NO ANSWER, BUSY
+${CDR(amaflags)}		DOCUMENTATION, BILL, IGNORE etc
+${CDR(accountcode)}		The channel's account code.
+${CDR(uniqueid)}		The channel's unique id.
