Roger,
so far, we have avoided stepping on the toes of the IFAX group, which is
what I think this would lead up to. Also, I do not see the real need for
this. If your output device happens to be a fax machine, your IPP Printer
should know how to contact the fax machine; it could even be sneaky enough
to include it a part of the Printer URI. I know that this would require a
unique IPP Printer id for every fax machine, but if you want to start
defining a fax off ramp (in IFAX terminology) as part of IPP, you are going
to need a lot more than just the phone number, apart from making enemies in
the IFAX camp.
In summary, I think we should leave this for implementors that might like
to provide bridges between IPP and IFAX (or current fax) in their products.
