+        If you want to go directly to postgresql database, and have the cdr_pgsql.so
+        compiled you can use the following sample setup.
+        On Debian, before compiling asterisk, just install libpqxx-dev.
+        Other distros will likely have a similiar package.
+
+        Once you have the compile done,
+        copy the sample cdr_pgsql.conf file or create your own.

+        Here is a sample:
