Services were automatically switched back to the active device immediately.

Services were switched back to the active device after the execute manualswitch command was executed on the active device.

If no operations were performed, at 09:00 next morning, the active device was processing all services.

Data generated during the period when the standby node took over services was not automatically synchronized to the primary node after the services were switched back to the primary node.

Terminals including IP phones on each node all register with the convergence gateway.

The convergence gateway routes inter-node calls.

Multiple convergence gateways can be deployed to work in active/standby or load balancing mode.

Periodically delete the log file.

Periodically back up the database file.

The log file needs to be periodically deleted and does not need to be periodically backed up.

AR routers in local branch scenarios do not provide the IP phone registration function in any case.

When a device on the central node is faulty and the AR router in the local branch scenario enables the local regeneration function, IP phones on both the central node and the local node register with the AR router.

When configuring the AR router in local branch scenarios, you do not need to configure user data. All user data is synchronized from the central gateway.

AR routers in independent PBX scenarios can provide diverse functions such as user registration, call routing, voice services, and automatic switchboard.

The central site uses two U1911s working in active/standby mode.

IADs can be deployed at a branch site separately.

It is recommended that U1960 be deployed at a branch site that has no more than 800 users.

The primary node in the center uses U1960, and the standby node in the center uses U1981.

U1981 cannot function as a branch node.

All types of users on the local node are synchronized from the central node.

On the central node, you can view the information about the licenses of the central node and local node.

The number of users on a local node that register with the central node cannot exceed the number supported by the license.

The BMU is a service management system in eSpace UC solution,

The BMU provides CDR-based charging.

The BMU provides self-service management.

The BMU supports role classification.

An SBC supports IP-based communication between the carrier networks and voice access devices, and between the headquarters and branches of an enterprise.

An SBC processes and controls data streams between IP networks in real time to support VoIP service implementation.

Generally, firewalls can convert only Layer 3 and Layer 4 headers. For UC applications such as SIP and H.323, the IP addresses required for exchanging signaling and media streams are contained in the packet payload; therefore, firewalls cannot perform NAT for private IP addresses at the application layer.

On the terminal, the SIP server address configured is the SBC address. The SBC functions as the signaling proxy, and media streams do not pass through the SBC.

The unified gateway provides an open and secure interface for a third-party billing system or center to obtain CDRs.

BMU provides the CDR query function.

Original CDRs are stored in the CDR pool of the unified gateway.

After CDRs are obtained from the CDRServer, the CDRs in the current folder are deleted and saved to the backup folder.

The eSpace server encounters exceptions.

The unified gateway encounters exceptions.

The firewall blocks port 8011 of the eSpace server.

The network between the PC where eSpace client is installed and the eSpace server is unstable.
