#1. Is the reporting capabilities of archival data better in R2? Right now, people typically buy FaceTime or write their own scripts to query SQL directly.
#2. Are some of the LiveMeeting "Hosted Service Only" features, like easy server-side meeting recording, available in R2?
#3. What is the migration/upgrade strategy, if it exists?
#4. Does Remote Call Control (RCC) still exist? LCS 2005 had more RCC capabilities than OCS 2007.
#5. G.729 codec support?
#6. Live Meeting High Fidelity Presentation (HFP) format 64-bit client codec support?
#7. Support for TAPI-based phone system integration without use of 3rd party add-ons?
#8. Better documentation? There are topics in the OCS 2007 documentation that are glanced over with a single sentence, when they should have a few pages worth of explanation. There are also sections that have a few pages of pictures and words that could be summarized by a single sentence. It goes both ways.
#9. Pick a dial plan/address book normalization scheme with the Exchange group and consolidate efforts? Enterprise voice dial plan format is different than Address Book normalization rules format. The integration pieces between Exchange 2007 and OCS 2007 R1 are not very straightforward to figure out and setup.
#10. Tools to mass modify Enterprise Voice AD attributes and RCC attributes?
#11. Ability to rename/change display of IM/PIC contacts in Office Communicator?
#12. Tools to prepopulate IM lists for new users?
#13. Ethical walls built in, not an API add-on after the fact?
#14. Updates from WSUS (almost there with the latest Category changes) for Office Communicator that offer a brand new .MSI instead of just .MSP (MSI transforms) that apply to the original release? It becomes a packaging/deployment hassle for enterprises.
#15. Full list of registry settings used by Office Communicator? Updated ADM/ADMX to support all the new options that have come out since OCS 2007 R1 RTM?
#16. Working TelephonyMode = 4 (TelephonyModeRccOnly) in Office Communicator? Currently broken in all Office Communicator 2007 R1 versions.
#17. Custom presence status messages without editing the registry/XML files? More than 4 entries available?
