Example of traditional LAI

Last Updated : Sep 08, 2012 |

The vectors in the sending Communication Manager use the goto command to determine whether the call must be sent to the receiving Communication Manager. Recall that the goto command tests various outflow threshold conditions such as expected wait time. If the expressed condition is met, a branch is made to the appropriate route-to command. This command sends the call to the receiving Communication Manager, which, as already noted, can accept or deny the call.

The following example shows an outflow vector that can be included in a sending Communication Manager.

Using LAI with route-to commands to outflow calls

1. wait-time 0 secs hearing ringback
2. goto step 5 if expected-wait for split 3 pri m < 30
3. route-to number 5000 with cov n if unconditionally
4. route-to number 95016781234 with cov n if unconditionally
5. queue-to split 3 pri m
6. announcement 3001
7. wait-time 30 secs hearing music
8. goto step 6 if unconditionally

If split 3 has an expected wait time of less than 30 seconds (step 2), step 5 queues the call to the queue at a medium priority.

If the expected wait time is more than 30 seconds, LAI attempts are made in steps 3 and 4. If the call is accepted by one of the receiving Communication Manager call control passes to the receiving Communication Manager.

If the receiving Communication Manager deny the call, the call queues to split 3 and announcement 3001 plays. The caller hears music, interrupted by announcement 3001 every 30 seconds.
