ABSTRACT:
A fax over Internet protocol client driver. The present invention enables a client to support a fax over Internet protocol. Whereas conventional systems commonly rely upon an Internet service provider (ISP) to support the fax over Internet protocol functionality, the invention ensures that a client can perform multiple Internet sessions, one of which is a fax over Internet protocol session. There is no need to disconnect from a current Internet session, and then re-establish another Internet session. The client is any number of devices including a personal computer, a laptop computer, a pen based computer, an Internet capable fax machine, or any other fax capable device. By providing a fax over Internet protocol driver within the client, the client can send a fax transmission over the Internet, even in the situation where the ISP that the client solicits does not support that particular functionality.
