Patton electronic SmartNode 4110 Series manual Distribution-Group Min-Concurrent setting

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-concurrentand timeout commands, you can configure the behavior of the call distribution. The distribution-group starts with min-concurrentcalls and after the timeout one destination call is added until max-concurrentis 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>

Step	Command	Purpose
1	[name](svc-dist)[name]# min-	Sets the minimum number of concurrent calls.
	concurrent <number>

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’.
