As ridiculous as it may seem for us techies, the email to fax option is still confusing for those less familiar with technology. People often make typos, try to attach Word documents, try to attach documents too large, etc. It seems to take care of the need for about 70% of our clients, but the other 30% who heavily fax we had to offer them an alternative platform. I think the Google Cloud Print would allow this other 30% to be able to use 2600hz based faxing again, but I do realize and understand the challenges in working with it.
