Fax over VoIP

I know it is old technology but,

Is it possible to find software that can send/receive a fax over VoIP - I
assume it is technically possible and all one has to do is find the correct
software.

So the answer is no, you can't

Yes you can, but it requires careful doing.

I use voipcheap for sending occasional faxes with a Fritzbox. I have not
changed any settings to accomodate fax.

HOWEVER, expect it to take multiple attempts and a lot longer than you would
expect. I find it OK for faxes every now and again but nothing more. There
is a previous thread in the group about Vonage's "dedicated" FoIP service,
but it doesn't sound like it's any different to my setup. I think they call
this emerging technology, but converting data to analogue audio to IP
packets and then back again sounds like a recipe for disaster to me.

Someone just needs to write software that emulates a fax modem and then
simply connects to a SIP provider to make the call and send the fax.

More like someone needs to write a working t.38 implementation for
Asterisk. Software that emulates a fax modem and then sends the data
over an IP connection using SIP will just run into all the same problems
an ATA with a fax machine plugged into it using g.711 codec currently
does. The problem is a fax transmission relies on near-perfect timing
at either end which is fine with analogue phone lines or ISDN. But IP
(and therefore the Internet) is a best-effort service which was designed
from the ground up with little or no consideration to synchronised
timing at both ends of a connection.
