I'm looking for some suggestions for hosted Fax solutions that could replace our on premise GFI Faxmaker server. The solution needs to work similar to how faxmaker does. The users would be able to fax by sending an email to a faxnumber@thefaxhostsdomain.
We would like to be able to receive faxes to a shared ftp location as well.
We will be porting our existing phone numbers, so keeping our existing numbers is a requirement.
What does everyone else use and what are the pros and cons to the service?
