i have CUCM Publisher , Cisco unity connection, Cisco Expressway- E , Cisco Expressway - C all these machine have been installed running fine, i need to know the scinario of configuration ( i need to check if understand am right or not , and also to get more info about that )

CUCM Publisher is integrated with Cisco unity using SIP trunk , as per my understanding of expressway ( information read from Cisco site) , the expressway edge will be integrdated with expressway - C ( expressway core ) , expressway - C ( expressway core ) will be integarted with CUCM Publisher.

expressway edge will be Published using Public IP , but i need to understand should i need CUCM IM Presence to be installed , if yes what integration needed to be done ( is just only the integration between CUCM IM Presence and CUCM Publisher ) , is there any integartion between Presence and Expressway core or edge ??
