/mcpTo restore the default setting, click Restore Defaults. By restoring the default value of 0 for the call charge/block, you effectively disable the other factors that are used in determining call cost. Factor Time of Day To further define the cost of calls, you can specify a multiplication factor for certain times of day. For example, if you want to charge subscribers a premium for daytime calls, you can apply a multiplication factor to the base charge/block that you specified in the Call Duration window. This section describes how to establish certain times of day when calls cost more. If you do not want to increase call cost by time of day, you can use the default values. The default multiplication factor specifies 1, so no increase in call cost for time of day occurs. Note Procedure Step 1 Choose Report Config > Rating Engine > Time of Day. The Time of Day window displays. Step 2 To add rows, click the Add Rows link. The system adds a row between 00:00:00 and 23:59:59. Step 3 To add additional rows, check the check box for the row above which you want to add a new row and click the Add Rows link. Note To delete rows, check the check box for the row that you want to delete and click the Delete Rows link. Step 4 Enter the From and To time ranges in 24-hour, minute, and second format. A 24-hour period, from 00:00:00 to 23:59:59, represents the default time range. If you want to set one time-of-day range from 8am to 5 pm, you will need to establish three time-of-day ranges: the first from 00:00:00 to 07:59:59, the second from 08:00:00 to 16:59:59, and the third from 17:00:00 to 23:59:59. Note You must use Coordinated Universal Time (UTC), rather than a 12-hour clock, when factoring Time of Day into Call Cost. Step 5 Enter the Multiplication Factor that designates a number by which you want the base charge/block to be multiplied when a call occurs in the specified time range. For example, if you charge a premium of double the price for calls that are placed between 8a.m. and 5p.m., the multiplication factor equals 2.00. A multiplication factor of 1.00 does not affect the cost of the call. Step 6 To add the time-of-day and multiplication factors, click Update .
