freeFAX.com is powered by the international tpc network which is a collection of fax servers in many locations around the world. Each fax that you send from freeFAX is routed through the tpc service and directed to the closest fax server to the recipient. The fax is usually sent within a few minutes but could take longer depending on fax traffic at the local fax server. After your fax has been delivered you will receive an e-mail confirmation from the server that sent the fax.
