[cisco-voip] CUCM 9 ELM Question

[Mark Holloway]

If I've got CUCM 9 Publisher and Subscriber nodes, plus Unity Connection, does ELM need to know about all of them or just the Publisher and Unity Connection?  If I try to add a Subscriber node to ELM it fails. In a prior CUCM 9 thread someone mentioned ELM only needs to know about the Publisher but I want to verify this is actually the case. I've been searching the docs but so far I haven't found the answer. Thanks!
