Hi, I have recently started working CUCM 7.0 and got stuck with a basic question. I have two IP Phones A and B. Both the phones are in PT-Internal and both the Phones have default CSS i.e. None.
My question is : Do we need to configure any CSS to get the Phone A talking to Phone B when they both are in same partition ? I know for sure that this is not required in CCM 4.x but in CUCM 7 i am not sure.
