I have been on the same path although I am using a TDM400. No matter what I did I could not get a fax to go through. Yesterday I moved the * server outside my firewall and the rest of the network and now I am making more progress. I blame it on old network hardware. I have two accounts, one with Broadvoice and the other with LiveVoip. The Broadvoice fax is going through with out any problems. LiveVoip faxing still fails. I would like to use LiveVoip so I will keep at it. -Scott
