Having the Call manager servers and VG in different locations

[ryan]

what are the main advatages and dis-advantages of have the VG and CM cluster seperatly other than there being more switches routers in the middle?

Hi Ryan,

CUCM and VG dont even care about it, you would have to make sure that you are meeting the bandwidth requirement for the protocol used between them.

I strongly suggest your read Cisco Collaboration SRND where different deployment models are documented and described well.
