You could try using SIP trunk for the integration instead of H323 ICT, but I am not sure if the presence state will be delivered accross it, worth a try.

Try to use a SIP trunk like Chris said, take a look on CUCM SRND to unterstand the concept.

"If the presence entity exists outside the cluster, Unified CM will query the external presence entity

through the SIP trunk. If the watcher has permission to monitor the external presence entity based on the

SUBSCRIBE calling search space and presence group (both described in the section on Unified CM

Presence Policy, page 23-9), the SIP trunk will forward the presence request to the external presence

entity, await the presence response from the external presence entity, and return the current presence

status to the watcher."

Thanks for the replies.

I saw that in the SRND, but thanks for posting it.  I guess it's confusing a bit because "presence" is a term used when maybe it shouldn't.  My understanding is when you see the line status in the corp directory, it's often referred to as "BLF For Call Lists", and not "Presence" since you're only seeing the line status.  So it's sometimes hard to understand when the SRND referrs to "Presence", if it's also referring to the directory, or just the product called "Presence", "Jabber", CUPC, etc.

BLF is presence.
