About linkage between an eSpace Desktop and an IP phone, which of the following statements are CORRECT? (Multiple Choice)
In the eSpace UC solution, the eSpace Audio Recorder in a single-node system indicates that the recording server, IMP server, database server, and unified gateway are deployed on the same server.
In an external network access scenario, an SBC and an enterprise firewall are deployed in parallel. Which of the following statements are INCORRECT as regard to the external eSpace Mobile authentication and registration processes?

If the console access code duplicates with the short and long numbers of a user, when a user dials the console access code, the call is directly connected to the short or long number. Then, the console services cannot be implemented.
Before installing the recording server in the eSpace Audio Recorder solution, install the SQL Server 2008 first.
In a multi-node centralized network, there is a central node with a U1981 deployed, and two branch nodes, one with a U1911 and the other with a U1960. When POTS user A under U1911 calls POTS user B under U1960, the path along which the call's SIP signaling is transmitted is ().
In the remote disaster recovery (DR) and local regeneration scenario (without considering registration update), assume that user A is a SIP user in the central site and user B is a PSTN user outside a branch site, User A calls user B through the gateway in the branch site. User A and user B are engaged in an ongoing call. At this time, the active device breaks down due to the central site power outage. Then, the standby device takes over services from the active device. In this scenario, which of the following statements is CORRECT?
There are three nodes in a distributed call management network (peer-to-peer mode). When SIP user A on node 1 calls SIP user B on node 2, () first performs number analysis.
In a multi-node centralized call management network, only the active node needs to be added for the local node, because the networking data of the standby node is simultaneously delivered by the active node.
You can configure IP phone linkage by creating a UC number and binding the UC number to an existing SIP number. The prerequisite for implementing this function is that ( ).
Which of the following URLs can be used to access the BMU administrator bgin page?
The SRU main control board of AR routers is the system control and management core, provides four FXO ports, and supports concurrent access of multiple channels to the PSTN.
Which of the following statements are CORRECT about the recording server functions in the eSpace Audio Recorder solution? (Multiple Choice)
U1900 series unified gateways are deployed in redundancy mode in an enterprise. One day, a communication fault occurs, so all users cannot make voice calls. The cause of the fault is that the active gateway breaks down, but the standby gateway does not take over services from the active gateway. In this case, which of the following methods is the most suitable?
In a single-node system network; all IP phones are registered with the same U1900.
Two U1981s are deployed in active/standby mode. By default, when the heartbeat connection between the active and standby devices has been lost for () minute(s) due to the active device fault, the active device is deactivated and the standby device becomes activated.
AR routers provide flexible slot combinations. Two SIC slots can be combined into one WSIC slot. Two SIC slots and the WSIC slot below can be combined into one XSIC slot by removing the guide rail.
The administrator can export the account file from the BMU, modify account information in the account file, and upload the modified file to the BMU to modify account information in the directory in batches.
eSpace Desktop fails to join a multimedia conference, and the system displays an error message (error code: 102) indicating the server connection failure. Which of the following possible causes is INCORRECT?
Which of the following components do NOT belong to the enterprise communications suite (ECS) in the UC solution? (Multiple Choice)
The procedure for configuring the mobile rich media function includes the following two steps: 1. Mount a storage device to the UMServer. 2. Configure the UMServer service.
In a distributed disaster recovery network, SIP users on the local node select the () as the SIP server preferentially.
The process for configuring outgoing calls on an AR router at a branch node is as follows: first configure the call route, then the prefix or trunk group, and last the trunk group or prefix. Which of the following is the logical process for the outgoing call route on the AR router?
