Fax to email is commonly known as internet faxing. The way internet faxing works is simple. SRFax assigns you a unique local or toll-free number. Anyone faxing a document to this SRFax number will be received by our servers. As soon as the fax transmission has completed, our system will convert the fax to a PDF file (or TIFF file if you prefer) and then send it as an attachment to you by email.
