[cisco-voip] upgrade PBX to Cisco call manager

[Vincent]

HI All,


I would like to know more info about upgrading my existing BPX to Cisco Call 
Manager or Unified.  would someone please guide me how to achieve this goal. 
I know how to configure the call manager, but upgrading is a brand new thing 
for me.  Also, could you please guide me the cost for what i have to pay, 
like license, which is yearly for the phone and what other fee.  Will Cisco 
Call save me money over the PBX system?

Thank you very much for your help and very appreciated.

Best Regards,
