Greetings from Sydney, Australia, where I'll be spending the next week (along with Kevin) at the UC Voice Ignite event. (If you're one of my readers and you're here too, look me up.) I want to capture some neat bits and info that you should know but may not. I can't put everything down, of course, and I won't post anything that I can't verify from publicly available material from Microsoft -- yes, Virginia, I take my NDAs seriously.
12:06: Exchange 2007 UM RTM didn't directly detct fax tone on incoming calls -- I didn't know that. Your IP gateway had to do it, then UM would renegotiate the media as T.38. SP1 changes that -- UM will detect fax tone, but the detection is off by default, you must manually enable. (source http://technet.microsoft.com/en-us/library/bb691398(EXCHG.80).aspx)
12:08: If you're planning on doing both Exchange 2007 UM and OCS 2007 using the same VoIP gateway, be careful it's certified for both! There is currently only one gateway (from Dialogic) that is certified for both applications. In theory, you shouldn't need two separate gateway products.

12:10: How do I know if Exchange 2007 UM works with my PBX/VoIP PBX? See the Microsoft Telephony Advisor and the IP PBX and PBX Configuration Notes.
12:12: Which IP PBXes connect to Exchange 2007 UM? At this point, Cisco Call Manager 6.x gives full interop (voice and fax), 5.x gives full interop for call answering, 4.x is not tested, and CallManager Express is not supported. The Mitel 3300 (v7.1 UR2) also supports direct interop (this is what we're using), but look at Interactive Intelligence CIC (v 2.4 SU13 at least). Avaya and Nortel CS1000 v5.0 require SIP proxies. Note that this is talking solely about Exchange 2007 UM interop, not OCS interop! (source http://www.microsoft.com/technet/prodtechnol/exchange/telephony-advisor.mspx)
12:19: During Q&A, it's already been noted that the 12:12 information is out of date. Moral of the story: many vendors are working hard on this, so keep a good watch on the previously mentioned websites and talk to your vendor!
13:35: Lunch was tasty! Added source links to previous points so it's clear I'm not posting any information under NDA. (Thanks, Kevin!)
14:47: Remember how you had to pick whether a UM Auto Attendant was DTMF-enabled or voice-enabled, but not both? Fixed in SP1. (source http://technet.microsoft.com/en-us/library/bb124501(EXCHG.80).aspx)
15:35: Lots of labs -- crunchy but not too deep for this first day.
Continue on to my day 2 notes.
