Exchange 2010 Unified Messaging (UM) has the following functional limitations when operate with Cisco Unified Communications Manager (CUCM) 7.1:
· CUCM 7.0 and Exchange UM support SRTP over SIP trunk. However, there are SRTP cipher suite mismatch issues which are causing interoperability to fail.
· CUCM 7.0 and Exchange UM support T.38 FAX. However, there are implementation issues which are causing interoperability to fail.
· During Exchange 2007 → Exchange 2010 upgrade, users whose mailboxes are still on Exchange 2010 may be prompted twice for their phone extension when they attempt to dial the pilot number to logon to Outlook Voice Access. For more information, please refer to section 6.1.
pls reply if these caveats have been solved with CUCM 8.0 or 8.5
