I think most everyone in the SIP Forum knows how the mechanism could work
using HI. The question was if we wanted to solve the issue using HI for
the SIP-Connect profile. I think the rationale for "no" was the feeling
we had on whether PBX's would actually support HI anytime soon, or whether
in practice we would actually be doing something different in deployment
to actually make calls work. (though I can't really speak for others - I
could be totally wrong on that, this was just the sense I got)
Speaking only for myself, I thought that the obstacle for SIPconnect was
that there was already a history-info-bis effort underway - we just weren't
excited about requiring support for a mechanism that was being revised. It
wasn't clear to me that we would be equally unexcited if 4244bis was
approved for publication.
But as Hadriel says, I could also be totally wrong about that. And other
people don't have to be shy about explaining things to me.
Thanks,

Personally, I look at it from a motivation perspective: who has the
motivation to change to make something work? In the SIP-Connect case, the
Service Provider is the one selling the SIP-Trunk service, so to win the
deal and satisfy customers they've got more of the motivation/burden to
make it work. The SP's also have a large motivation to support as many
IP-PBX vendors as possible. Any changes we mandate of IP-PBX vendors will
reduce the pool of them that are "SIP-Connect compliant", which is not
good. Especially when what we're proposing basically works *now* in
SIP-Trunk deployments - i.e., there's running code. It doesn't quite work
that way today within the SP's domain on the wire, but as I said they have
the motivation (and the ability) to change their side.
