I was wondering if it is possible to send a Fax via ASP.NET without using proprietary Fax software (i.e. using all .NET native classes)
All I am after is to send a generated PDF to a remote fax machine rather than a printer.
There is this question already, however this chap uses a 3rd party program as the Fax software
EDIT: We have no control over the remote Fax and will have little to no visibility of how the Fax is set up.
You might find it easier and more reliable to use a third party service that will send the fax for you. There are services out there that are preety cheap and have web service front ends.
This way they will handle all the retry logic for example when the line is busy or circuts are busy etc etc…
This also decouples your web server from sending the fax. If you send the fax within the Asp.Net request pipeline, I can only imagine what that might do to the scalability. Not to mention what happens when five users all send a fax at the same time.
