Summary:                    [patch] Generating output using cdr_custom backend
is corrupt because of pbx.c
Description: 
Then use cdr_custom with use this fields in cdr_custom.conf:
simple.csv =>
${CDR(answer)},${CDR(src)},${CDR(dst)},${CDR(billsec)},${SHELL(echo -n
test)}

Used dialplan sample:
exten => 100,1,Answer()
exten => 100,n,Echo()
exten => 200,1,Wait(100)
And make calls: 100 (answered call) and 200 (unanswered call)
Then in sample.csv I have this output:
4400,100,2011-05-18 08:49:22,3,3test
4400,200,4492,0,0test
Third and fifth field are corrupted. Fifth field append result to previous
value. Third field copy previous value if result is null.
This is because in pbx.c string variable are not reseted in all cases.
With my patch output get corrected:
4400,100,2011-05-18 09:06:15,10,test
4400,200,,0,test
