Configure Fax Modem to Operate at Certain Times

Hi. I would like to know if anybody here is familiar with configuring a fax modem set up on a SBS Server 2003. I would like to set a schedule on the usage of the fax modem – no sending between 8pm to 8am. In the console there is an option ‘Discount Rate Hours’ which will only allow sending of faxes marked ‘Discount Rate Only’ during hours with discounted rates. We are using outlook for our faxes. The process is as follows: Users send a message to a ‘Business Fax’ contact using the fax mail transport, which sends the fax to a shared fax modem that is on our servers. Thanks.
