I told my somewhat tech-savvy sister to create an SRV record in her DNS.
 She asked me if I was having a stroke.

Maybe your average users are smarter than the average average user.

I am sure that everyone here either knows how to do this or can figure
it out.  We aren't exactly a mass market.  BTW, I am SIP:darcy at Vex.Net
or SIP:darcy at VybeNetworks.com.  That still goes through the proxy
though.  It's a separate issue to direct phone-to-phone calls.

If everyone had public IPs on their phones we could do a partial
solution.  Use the proxy to set up the call then hand it off to direct
P2P.  Tech savvy users could do that or we can wait for IPV6 and give
every phone (as well as every "thing") it's own public IP.  That won't
work in the interim though as my previous email showed.  My client's
phone had a public IP and mine, as most users, did not so it failed.

Of course.  The discussion was about avoiding that.

I could also do it and, because of the phones that we use, I can put
your minimal luser on the net with a modem (in bridge mode) our
telephone and one computer.  The phone would have a public IP and, with
our DSL, could even have a static, public IP.
