I have Hylafax running on my Elastix box and I am using the Hylafax Client Pro on my computer. When I start the client on my PC I get the following message: "No connection to the server could be made". I have verified that port 4559 is open on my firewall and on the firewall on the PBX (located at another location). I have tried using Passive FTP, the administrator/password and all various possibilities on the client. Is there a step to setting up Hylafax on the server that I may have missed? Hylafax is running on the server.
