[Serusers] Fax and SIP

Maybe not specific to ser, but I think this issue may be intresting to serusers... I think business voip solution would have a major added value if they could offer fax service. After some googling around it seems that fax over IP protocols (T.38) are somewhat unreliable. Ok now some loud thinking: enters SIP, and we all well know that SIP is media independent, so could I send documents instead of voice? I mean having two SIP endpoints which can transfer, say, a postscript file. Then we should build SIP fax machines which can scan documents to ps and send and receive via SIP, and as well build PSTN gateways which receive from SIP and simply pass ps data to some fax server like hylafax. Do you thik this is possible? Am I delirating? ciao -- Giovanni Balasso giaso(a)yahoo.it
