Hi Vinay,

It looks like (from the attached Server Support Matrix) that this box would work if the Memory were upgraded;

Cisco CallManager requires a minimum of 1GB of memory on the Cisco CallManager servers. To avoid system problems, such as dropped calls, verify that your servers have a minimum of 1 GB of memory installed. If the installation process detects less than 1GB memory on the publisher server, the installation aborts. The installation process performs a similar check on the Cisco CallManager subscriber server; it allows the installation to continue if it detects less than the minimum requirement.
