Widnows verison CCM 5.01
I guess the major change is to support to SIP protocal.
Still have no paging system feature.
Any good to upgrade from 4.1 to 5.0??
CM 5.0 is only linux based. SIP is big in CM 5.0. and its an appliance based box. I dont think paging is roadmapped yet. I would say that you run 4.1 for now, until 5.0 gets stable. I am sure after a few months Cisco will have bug fixes and patches in a new release 5.0(x) (x=1,2,3 etc).
Meanwhile your next upgrade path, if you want to stay in windows, may be to 4.2 to get some of the new features that have been added in CM 4.2 (still windows based).
PS: please remember to rate replies!
As Sanker states, CCM 5.0 is currently only appliance based on Linux. You can't obtain S/W and upgrade a 4.1/4.2 system today.
CCM 5.0 has some significant changes/additions in the SIP, AD, CAC/RSVP, Licensing, Patching facilities amongst many other changes. I've had the opportunity to tinker with a V5 system and it really is a different approach with a new front end GUI also.
It will be at a later date when V4.2/V5.0 come together in a new major release after which it should be possible to upgrade a Windows system.
I'm sure for now many existing installations will take a cautious approach and await the bugs/stability issues to be identified.
Realistically you should be looking at getting an appliance in the lab for familiarisation or only consider it for new installations...just my thoughts.
You are sure?
Following documnet consider different view:
"Cisco Unified CallManager provides a choice of operating system, either a Windows-based server (release 4.x) or the appliance model (release 5.0) The feature enhancements listed in this section are available only on the appliance model at this time."
It is possible to upgrade from CCM 4.1 to 5.0.
As per the Upgrade guide "Cisco CallManager 5.0(1) uses a different installation framework than previous releases. The installation process allows you to perform a basic installation, upgrade from Cisco CallManager 4.x to Cisco CallManager 5.0, and upgrade to a newer service release during the installation"

From Cisco Parter publication:
"Appliance Model implementation for call processing; ships with operating system and Cisco Unified CallManager application software
pre-loaded on MCS platform and optionally available as a DVD kit for customer-provided servers"
Q. Will Cisco Unified CallManager 5.0 be available in a Windows-based appliance model?
A. Cisco Unified CallManager 5.0 is available only in a Linux-based appliance model implementation at this time. Cisco Unified CallManager 4.x
remains available as a Microsoft Windows-based server implementation.
Q. How much do Cisco partners or customers need to know about Linux?
A. Cisco Unified CallManager has deployed the Linux operating system in an appliance model implementation. The Cisco Unified CallManager
application is loaded along with the operating system on a dedicated server. There is no need for partners or customers to know Linux in order to
install or operate Cisco Unified CallManager 5.0.
