Call router configuration task list 505
SmartWare Software Configuration Guide 40 • Call router configuration
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.
Mode: context cs
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.
Step Command Purpose
1 node(ctx-cs)[ctx-name]# service
priority <svc-name>
Create a priority service.
2 node(svc-prio)[svc-name]# port
<port-name>
Create a port within the service.
3 node(port)[port-name]# route
dest-….
Define the routing destination for calls received on this
port.
4
(Optional)
node(port)[port-name]# service
priority
Define the priority for calls received through this port.
(The default priority level is 0)
5 node(port)[port-name]# exit Leave the port configuration mode
6 Repeat steps 2 to 5 for any additional calls you need to
create.
7
(Optional)
node(svc-prio)[svc-name]# max-
calls-to-drop <calls>
Define the maximum number of lower priority calls to be
droppedif a higher priority call fails. (Default is to drop
any lower priority calls.)
8
(Optional)
node(svc-prio)[svc-name]#
quiesce-time <seconds>
Define the time for which lower priority calls are
blocked after a higher priority call failed. (Default is
15 seconds.)
9
(Optional)
node(svc-prio)[svc-name]# retry-
timeout <seconds>
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.)
