If you're using the cdr_adaptive_odbc backport (for 1.4), you can work
around this limitation by using aliases:

cdr_adaptive_odbc.conf:
[first]
dsn=mysql1
alias dst => does_not_exist
alias realdst => dst

extensions.conf:
exten => _X.,1,Set(CDR(realdst)=${EXTEN})
...

If you're using 1.6, there isn't a problem, because CDR(duration) will never
return zero except during the first half second of a call.
