[cisco-voip] IOS for CME 4.2?

[Kelemen Zoltan]

Hi,

A client with CMExpress asked for Extension Mobility feature. As far as 
I understood it though, I would need CME 4.2 to implement extension 
mobility in an express system.

The question is, what IOS do I need for that? From the compatibility 
matrix I got 12.4(11)XW2, but the feature list of that image does not 
contain anything above CME 4.0(3)

So is the feature list incomplete, or am I looking in the wrong place?

Thanks,
  Zoltan
