Hi all,
CUCM8.6
We have a 6-7 Cluster CM, i need some help with one of our sub on a site that is no longer registering new extensions/phones, after some troubleshooting; found out that, the sub is Off-Line with Replication Setup (4)
My concern is only the 172.16.4.31(sub) ive checked utils service list, db, dbreplicator, DLM is all started, nothing of the unusual
Output from PUBLISHER

Output from SUBSCRIBER

Ive read thru several videos & doc, it suggest to do a dbreplication stop, reset, repair etc.
My question is; doing that these dbreplication command does it require downtime? Does it affect all current phones registered to my subscriber(172.16.4.31)?
Appreciate any advise.
