Call router configuration task list 508
SmartWare Software Configuration Guide 40 • Call router configuration
Note It does not make sense to configure the maximum number of concurrent
destinations but no timeout, though the software does not prevent this con-
figuration.
Distribution-Group Min-Concurrent setting
A new command in the call-control’s distribution-group service lets the user specify how many of the config-
ured call destinations should be tried first:
min-concurrent <number>. Together with the max-concurrent
and
timeout commands, you can configure the behavior of the call distribution. The distribution-group starts
with min-concurrent calls and after the timeout one destination call is added until max-concurrent is reached.
Then, again after the timeout, a call to the next destination is placed while the first destination call is dropped.
Mode: service distribution-group <name>
Example: To configure a distribution group that first rings on the phone#1 and then, after 5 seconds, on
phone#1 and phone#2, enter the following commands:
node(svc-hunt)[service-name]#min-concurrent 1
node(svc-hunt)[service-name]#max-concurrent 2
node(svc-hunt)[service-name]#timeout 3
node(svc-hunt)[service-name]#route call dest-interface PHONE1
node(svc-hunt)[service-name]#route call dest-interface PHONE2
Call-router ‘limiter’ service
The call-router ‘limiter’ service limit offers a flexible technique to limit the maximum number of concurrent
calls within the system. It also limits the call-setup rate within a system. Calls exceeding the defined limits can
either be simply dropped or they can be handled differently. A call is counted as an active call as soon as the
call-setup message reaches the limiter service. The call remains active until the signaling has completed tearing
down the call.
In the figure is a call-router configuration which uses the limiter service to limit the maximum number of con-
current calls between SIP and ISDN to 20. In this scenario, if the limit is reached, any additional call received
from sip will be dropped. If however an additional call arrives from ISDN, it will be forwarded to the special
ISDN interface called ‘voicemail’.
