Asterisk and fax calls
Fax over IP
In short:Across the Internet even a G.711 codec fax transmission is unpredictable. An excellent discussion of why faxing and modems don't work well over VoIP can be found here. However, people often get perfectly good results on lightly loaded LANs. It still isn't perfect, as a burst of data on the LAN can still upset things, but some people get results they can live with.
