Hi<br><br>I'm looking at the <a name="Print_Area">Cisco Unified CallManager
Compatibility Matrix document at the link below and wonder if anyone can clarify what 'Additional
Tested Upgrades' means exactly. I'm looking to upgrade a customer from 4.02a to 4.2.3 and want to make sure when I put the 4.2.3 CD in the drive it won't give me the business. <br><br><br><br>http://www.cisco.com/univercd/cc/td/doc/product/voice/c_callmg/ccmcomp.htm#RANGE!A26
