Which two pieces of information can be gathered about the calls traversing these border elements? (Choose two.)

  1. The total number of calls is 150.

  2. The number of non-native calls is 70.

  3. The number of native calls is 501 .

  4. The number of calls preserved is 220.

  5. The total number of active calls is 100.

Answer: A,B Explanation:

To check for native and nonnative (preserved) calls when both are present The numbers of calls on the system are shown as follows:

Total number of calls = quot;Number of calls in HA DBquot; quot;Number of calls in HA sync pending DBquot;. This is 100 50 = 150 in the example output below.

Total number of preserved (nonnative) calls = quot;Number of calls in HA preserved session DBquot;. This is 70 in the example output below.

Total number of native calls (calls set up since the failover and therefore not preserved over the failover) is the difference in the previous two numbers. In this example, it is 150 – 70 = 80.
