I'm not sure what B. Whittaker is "trying to ask" here, but to make it
clearer for him:
- as it's been mentioned, fax on VoIP (encoding fax directly in a G.711
RTP stream) is not reliable, so you may forget about that
- but you can have T38 and VoIP in the same network architecture, a lot
of VoIP gateways also feature T38 relay
- "normal phone lines" only support "standard" fax protocols, you have
to use adapters to connect your (analog) fax machine at one end, and
adapters (gateways) to connect to (analog or numeric) phone lines at the
other end if you want your fax traffic to go over IP.
