I have 2 CUCM 7.15 clusters. They are connected via a “Inter-Cluster Trunk (Non-Gatekeeper Controlled)”. Calls and caller ID pass between them just fine.
Phones in one cluster can see the line status of other phones in the same cluster when I check missed calls, placed calls, corp directory, etc.
I am trying to get the line status in the corporate directory to display for ALL phones, including the phones in the other cluster. Is this possible? I do not see a “SUBSCRIBE Calling Search Space ” field on a “Inter-Cluster Trunk (Non-Gatekeeper Controlled)” – but I do on a SIP truck.
Do I need a SIP trunk to pass presence (line status) information? If so, I assume I can ditch the old trunk and just use SIP for both calls and line status? Would this also allow the Attendant console to see line status of phones in the other cluster? All phones are currently listed in the corporate directory.
Am I barking up the right tree? Any advice\pointers would be greatly appreciated.
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.

No. You will only need the SRST licenses on the primary router. Because this feature...
