[hasan yenilmez]

Hi , I am newbie on telepresence  deployment . Actuallay I don't know which device does what .

we have  virtual machines . cucm , im&presence and Cisco Telepresence Video Communication Server  

 As ı read   Cisco Telepresence Video Communication Server should be configured  as Cisco Expressway-C Server and E server .      

And we have physical Telepresence Server 310 .

Expressway C sits in your internal network and Expressway E sits in the DMZ/public networks. CUCM connects to Expressway C and Expressway C connects to Expressway E. When an endpoints registered in CUCM tries to call an endpoint that doesnt belong to your organizations, the call flows through CUCM <> Exp-C <>Exp-E. 

TP 310 is a conference bridge which registers to CUCM and is used for mixing video streams.
