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 SIP user A under U1911 calls POTS user B under U1960, the path along which the call's SIP signaling is transmitted is ().
In the eSpace UC solution, before backing up the database, specify the backup policy, including the backup period and data save duration.
About the standby node configuration in the disaster recovery scenario, which of the following statements are CORRECT? (Multiple Choice)
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?
Which of the following statements are CORRECT in the CDR and billing scenario? (Multiple Choice)
In a multi-node centralized network, the status of SIP users of the local node is normally displayed as () on the local node.
During software installation, you can first install the eServer and then the BMU and database.
In remote disaster recovery scenarios, when the active node (U1981) is faulty, POTS user A on a branch node (U1911) makes an outgoing call to local PSTN user B through the branch node. Which of the following is the path along which the SIP signaling of the call is transmitted?
What are the possible causes when eSpace Desktop fails to initiate an instant conference? (Multiple Choice)
A group customer deploys two U1981s in active/standby disaster recovery (DR) mode and deploys a U1960 in both branch A and branch B as the local gateway. One day, due to the carrier network fault, the U1960 in branch A cannot detect the heartbeat of the active and standby U1981s, but the heartbeat connection between the U1960 in branch B and the active and standby U1981s is normal. In this scenario, which of the following statements is CORRECT?
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.
In the eSpace UC solution, which of the following components need to connect to U1900 series unified gateways? (Multiple Choice)
Which of the following statements are CORRECT as regard to UC multimedia conferencing functions?
(Multiple Choice)
In a multi-node centralized network and not supports two unified gateways working in active/standby mode,() SIP server(s) need(s) to be configured for users on the central node.
About the console service, which of the following statements are CORRECT? (Multiple Choice)
In a local regeneration scenario, some IP phones in an office of an enterprise branch can successfully register with the AR router in the branch. However, in the case that the configurations and licenses are correct, conference calls cannot be initiated between the IP phones. If the preceding problem is caused by a damaged hardware, which of the following damaged hardware may result in the problem?
In the eSpace UC solution, an SQL Server 2008 R2 of the standard edition is used with the eSpace Audio Recorder in a single-node system.
If a user links his or her eSpace Desktop with an IP phone and both the eSpace Desktop and the IP phone work properly, which of the following statements are CORRECT when another user calls the linked number of the user? (Multiple Choice)
The eSpace UC solution provides end-to-end security networking schemes, including (). (Multiple Choice)
After an attendant successfully logs in to the SoftConsole, the attendant is displayed in the unsigned-in state. Which of the following are possible causes? (Multiple Choice)
In a service scenario, if you want to use the BMU for CDR query, which of the following configurations are CORRECT? (Multiple Choice)
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 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. After a call from SIP user A under U1911 to POTS user B under U1960 is connected, the path along which the RTP streams are transmitted is ().
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.
Which of the following URLs can be used to access the BMU administrator bgin page?
IP phone user A and IP phone user B register with the same AR router, The AR router does not connect to the PSTN. After A successfully calls B, A can properly talk with B. The call is an () call.
