we have UCM 6.1(5), CuciMoc 8.0.1 and OCS 2007 R2. CUCIMOC queries LDAP for every new number and all calls are logged to Conversation History window. Everything is OK for numbers that are stored in LDAP but the problem is with numbers that are not in LDAP. CUCIMOS sends a search request to LDAP which sends back 0 results in searchResDone packet. The call is logged in Conversation History as Unknown (Work) without any detail of Caller ID number. Why caller number isn’t displayed in Conversation History?
