VoWIFI from your cell phone is essentially the same thing, except your

Yeah, I got the IPsec part right away. I guess they figure once it's in
an encrypted tunnel it's nobody's business what's in it :)

Look up VoLTE.
Yeah I did, and confirmed it's just SIP+RTP over IP. Which is why
it's so frustratingly hard to find the same simple diagram or
whatever for vowifi.

Yeah, no kidding. It's like acronym soup. I've been trying
all afternoon
to figure out vowifi and am now pretty certain that it's just
SIP
signaling over IP. But it's been really frustrating because I
still
haven't managed to find "RTP" explicitly. I would assume that
if you use
SIP you're probably going be shipping RTP packets for media,
but it's
amazing how hard this has been to confirm, and I've tried to
find this
out more than once. I even stumped Dave Oran...
