Source notes citing this source

• By default, HTTPS networking does not replicate system distribution lists and their membership; the HTTPS link setting 'Include distribution lists and membership when synchronizing directory data' turns it on. in context
• If RTMT raises a NetworkLoopDetected alert, Cisco says to find the loop with the Network Analyzer tool and then unjoin and rejoin the affected locations in the correct hierarchy. in context
• When an SSL-enabled HTTPS link is created, Unity Connection checks that the IP address, FQDN or hostname entered matches the remote location's web SSL certificate; if not, enter the matching value or tick 'Ignore Certificate Errors'. in context
• The CLI command 'utils cuc networking synchttps' resynchronises selected data across an HTTPS link or location, by USN (up to 10 per command), by object type, or by recorded voice name. in context
• To check replication, compare the Last USN Sent, Received and Acknowledged fields on the Edit Unity Connection Location page; if they stop incrementing, replication may be stalled, and the system re-requests records after a default five-minute timeout. in context
• A shortage of available voice messaging ports can stop cross-server transfers; Cisco suggests checking port use with the Unity Connection Port Usage Analyzer. in context
