flexfax: routing Faxes

[Alvaro Rosales <alvaro@procacao.wintersperu.com.pe>]

Hi friends , I have a question , Is there a way to make the routing of
faxes automatic ? I mean what criteria can I use to route faxes ? I{ve
heard that the only way to route faxes is trough the telephone number of
the sender ,Is there other way ?? , what happens is I have two modems ?
can I send those faxes to a different directory ??
