• Intersite and HTTPS directory replication use a Feeder service and a Reader service: the Reader polls the remote Feeder for changes since the last poll, and the Feeder answers from its change-tracking data. in context
• For an intersite link, one location in each site acts as site gateway, and all directory synchronisation and voice messages between the two sites pass between those gateways. in context
• System contacts, system distribution list membership and VPIM locations and contacts are not replicated between sites over an intersite link. in context
• The Release 15 networking guide and system requirements say every server in both sites must run Unity Connection version 15 before two sites can be linked. disputed in context
• A legacy Unity Connection site (intrasite networking) can contain at most ten Unity Connection servers or clusters, called locations. in context
• Within an intrasite network, every location uses SMTP to exchange both directory synchronisation information and voice messages directly with every other location. in context
• In legacy (intrasite/intersite) networking the global directory limit is 100,000 users and system contacts combined, with the same limits on distribution lists as HTTPS networking. in context
• Legacy networking tracks directory changes with Unique Sequence Numbers (USNs): each change increments the location's USN by one and is recorded in its database. in context
