answered). If the u option is specified, this value will be returned as an integer

complete). If the u option is specified, this value will be returned as an integer

The following options may be specified:
l
All results will be retrieved from the last Call Detail Record for the call, in the case
of using multiple CDRs via ForkCDR().
r
Custom CDR variables will be retrieved from the last Call Detail Record, but the
standard fields will be retrieved from the first.
u
The unparsed value will be returned. See the fieldname list above for entries that
are affected by this flag.
You may also supply a fieldname not on the above list, and create your own variable,
whose value can be changed with this function, and this variable will be stored in the
CDR.
