I have a customer with CME on version 4.1 currently. He is experiencing a known bug where unanswered calls to an overlayed DN do not get logged as missed calls. As this overlayed DN is their main published number they can't see if they are missing important calls. This bug is detailed in:
The Cisco notice syas that the bug has been fixed in IOS versions 12.5(0.7)M, 12.4(18.4)T1 and 12.4(24.5.1)PIX11. We are looking to upgrading the CME version to 7.1 and Cisco recommend that the IOS versions for 7.1 are 15.0(1)M, 12.4(24)T or 12.4(22)YB - none of which are listed as having the bug fix in the above document.
Can anyone please tell me if any/all of the recommended IOS versions for CME 7.1 have this particular bug fixed as I don't want to go through the pain of an IOS/CME upgrade if the fault will still be there?
No I did not and I will not be able to.
But I know the Cisco code maintenance logic and I know that when is fixed in one version, it gets propagated to all versions.
