Figure 70. Priority service diagram
By default, the service drops any lower priority calls if a higher priority call fails. However, you have the option
to limit the number of lower priority calls to be dropped if a higher priority call fails. It also blocks new lower
priority calls for a configurable time after a higher priority call failed.

The following procedure demonstrates how to configure a priority service.

Note
Although this service improves the probability that higher priority calls can
be established successfully, there is no guarantee that a higher priority task
can be established successfully at any time.

Define the time for which the service waits after a
higher priority call failed until it tries to establish it for a
second time. This allows resources used by dropped
lower priority calls to get available again. (Default is
3 seconds.)
