+- rate_detail: the rate determined for this call (L<FS::rate_detail>)
+- minutes: the maximum number of minutes to be charged
+
+Finds available usage minutes for a call of this class, and subtracts
+up to that many minutes from the usage pool. If the usage pool is empty,
+and the C<cdr-minutes_priority> global config option is set, minutes may
+be taken from other calls as well. Either way, an allocation record will
+be created (L<FS::cdr_cust_pkg_usage>) and this method will return the
