I posted a comment on the blog, but it does occur to me that this is a
better forum for a back-and-forth discussion than perhaps the Comments
section on that page. The phone looks very nice, and I think that
this kind of feature set will sell well - good to see some innovation
from Cisco phones! The Bluetooth capability is really nice. It would
be amazingly far-sighted of them to have Bluetooth association create
SIP NOTIFY events - would that be the enabler for all sorts of
interesting features or what? When you (or at least your Bluetooth
headset) sit down at your desk, the phone could send a NOTIFY and
calls start flowing to your desk. (or "REGISTER" - not sure which
would be more appropriate.) When you move away, the SIP server is
NOTIFYed that you are away, and routes calls to your cell phone.
(Yes, I know, I'll stop my crazy talk about "features" and
"innovation" - it just gives developers headaches.) This is of course
all stuff that Asterisk can or could do easily as the core, and allow
those components to be accessed quickly by the huge development
community. But of course that only means hardware revenue for Cisco,
and no Call Manager revenue. The Open Source barbarians might storm
the gates in San Jose with swords made out of Linksys phones. But I
don't particularly care about the internal contentions in CSCOs
product group - I'm only interested in what features are available on
equipment I (we) can use.

I'll throw a few more bones of contention out to see if you or someone
else on the list know better than I some of the answers:

No G.722 of any sort? Surprising.

Also: I've been remiss in keeping up with these for a while. Can XML
URLs be pushed into the phone on an INVITE yet or is that still a
"complex feature" only available on the proprietary protocols? In
other words: do a screen pop on the phone when a call comes in with
some arbitrary web-based data displayed?

I've tried beating that idea into the heads of the Sipura/Linksys/
Cisco people for literally 7 years now, and there has been a
resounding silence. Doesn't this seem like an obvious feature? When
a call comes in, have DATA on that screen instead of just caller ID.
I've heard various hemming and hawing about "Oh, well, XML would be
too slow" or "That would require a new RFC!" and nonsense of that
ilk. Bollocks! They do it on the SCCP phones, and SIP accepts easy
header extensions with no new RFC. This has been bald-faced
intentional feature absence so that the SIP phones didn't steal the
show from the bulky and proprietary Cisco back-end products. If those
SIP phones could do it, Asterisk would eat MORE of Call Manager's
lunch than it already has. Maybe I'm frustrated about something that
has been possible for a long time on those phones - it's been a few
years since I really delved into the manuals on the SPA software
loads. Do you know if it is possible yet to do screen pops on the SIP
images of these phones via an XML URL?

PS: MP3's from the speaker on the phone? Err... why? Cool feature
and everything, but mono audio from a speakerphone is not exactly
"listening pleasure" material.
