You've gotta be using a different "SIP" from the SIP I'm used to.

A basic configuration has "name", "user name", "domain", "realm",
"authentication name" and "password".  That's just for me.  Then I've
got "Registrar", "Outbound Proxy" for the server.  Now codecs turn out
the be important.  Twinkle has 5 different ones for speech, and 4
different ways of sending DTMF codes (the default one didn't work for
me -- I had to experiment to get it to work).

That doesn't cover a couple of dozen checkboxes and minor switches.

Voicemail, hold and other features have another giant selection.  In
fact, I've never got voicemail notification to work properly, although
if I remember the right number to call and the PIN then I can at least
now log in to my voicemail and pick up the messages.  Way to go, all
the usability of a regular phone.

Is this the 1890s?  Do I need to remember a NUMBER to call someone!!
I've got a keyboard here and at least 3/4s of it has these things
called "letters" where I can type "words".
