implement centralized IP telephony

We need to implement a project which is based centralized IP telephony sip through a softswitch,

and see the availability of voice mail and instant messaging could someone help me decide I need? I was thinking about a similar scenario attached. greetings and thanks

implement centralized IP telephony

Dude,  did you mean to have a CUCM in that picture as well?  Technically your centralised cluster with Presence, CUC and CUCM,and SRST will work. 

Please remember that this is a technical forum, for a Bill of Materials; you will need to engage your Cisco Contact or reseller.
