asterisk users - Sep 2005 - Asterisk Realtime.. : Unixodbc drivers

Hi!

About realtime...
Anybody knows a unixodbc driver for oracle (free or comertial)?
I am working with a trial easysoft odbc-driver, but the commertial license
is very expensive...

Another question.
res_odbc.so works with IODBC ?

Regards.
