Is it possible that this only works with a "compiled" config?  I've been
trying do the above, but with the XML config, and I'm not getting
anywhere.

Oh well - I wonder what I'm doing wrong then.  I've been trying to get
this to work for most of last week.

Do you push it from Asterisk or somewhereelse?  Again, I can't make it
work. I've got "Auth resync-reboot" disabled on the SPA, so it
shouldn't be asking for authentication, but the SIP NOTIFY goes out,
and the phone does nothing.
