Use the Call Notification commands to configure call notification criteria as part of the SBC's call notification feature. For deployments requiring notifications when calls are set up by the SBC, you can configure the SBC to send SIP NOTIFY messages to a specified Application Server when a call's calling party or called party matches criteria you specify. Refer to Sending Unsolicited Call Notifications to Application Servers for more information on the call notification feature.

Call Notification Criteria

Use the callNotificationCriteria object to specify individual sets of criteria (called party, calling party, trunk group for the other call leg) that the SBC's Embedded Routing Engine (ERE) compares against calls. This object also identifies the servers, using a cnsGroupCluster, to notify in the event of a match.  

Command Syntax

% set global servers callNotificationCriteria <criteria ID>
     calledPartyId 
     calledPartyType <AoR | number>
     callingPartyId
     callingPartyType <AoR | number>
     cnsGroupClusterId <cns group cluster ID>        
     otherLegTG 
     role <egress | ingress | none>
     userPartType  <none | useCalledNumber | useCallingNumber | useConfigured>
       userPartValue

Command Parameters 

callNotificationCriteria Parameters

ParameterLength/RangeDescription
<criteria ID>

up to 23 characters

Specifies a name for the set of call notification criteria. 

calledPartyId
up to 134 charactersSpecifies the called party user to match.  The value can be a specific calling number, prefix, calling uri or the "*" character. The default value is "*" which matches all.
calledPartyType
  • AoR
  • number
  • *

Specifies the format in which the called party is identified in the criteria. The options are:

  • AoR
  • number
  • * (a wildcard character to match any called party)
callingPartyId
up to 134 charactersSpecifies the calling party user to match. The value can be a specific calling number, prefix, calling uri or the "*" character. The default value is "*" which matches all.
callingPartyType
  • AoR
  • number
  • *

Specifies the format in which the calling party is identified in the criteria. The options are:

  • AoR
  • number
  • * (a wildcard character to match any calling party)
cnsGroupClusterId
up to 23 charactersSpecifies the name of the call notification server (Cns) group cluster that should receive NOTIFY messages when a call matches this set of criteria.
otherLegTG
up to 23 charactersSpecifies the name of a SIP trunk group for the other call leg to match. The value can also be the "*" character which matches all.
role
  • both
  • egress
  • ingress

Specifies on which call leg to apply the criteria. The options are:

  • both – (default) applied on both ingress and egress.
  • egress - applied when the trunk group to which the criteria is attached is the egress trunk group.
  • ingress - applied when the trunk group to which the criteria is attached is the ingress trunk group.
userPartType
  • none
  • useCalledNumber
  • useCallingNumber
  • useConfigured

Specifies what to use to populate the userpart in the Request-URI within NOTIFY messages. The options are:

  • none (default)
  • useCalledNumber
  • useCallingNumber
  • useConfigured (requires you to specify a static value for the userpart using the userPartValue parameter.)
userPartValueup to 23 charactersSpecifies a static value for the userpart of the Request-URI within NOTIFY messages, only if you specify the userPartType as useConfigured.

Call Notification Criteria Group

Use the callNotificationCriteriaGroup object to group up to 32 callNotificationCriteria objects that you can then assign to a SIP trunk group. For calls on that trunk group, the ERE compares the calling number/called number and other-leg trunk group against the criteria in the group. The callNotificationCriteriaGroup specifies the sequence in which the criteria is evaluated. Once a call matches one of the callNotificationCriteria objects, the matching process skips the remaining criteria in the group and the SBC initiates its notification process. 

Command Syntax

% set global servers callNotificationCriteriaGroup <group ID>
     callNotificationCriteriaGroupData <sequence: 0 - 31>
        callNotificationCriteriaId <call notification criteria ID>
     description

Command Parameters

callNotificationCriteriaGroup Parameters

ParameterLength/RangeDescription
<group ID>

up to 23 characters

Specifies a name for a group of up to 32 sets of call notification criteria. Sets of criteria are identified within the group by a sequence number.

callNotificationCriteriaGroupData
<sequence>		0-31Specifies a sequence number for a set of call notification criteria within the group. The SBC checks for a match in sequence order until it finds a match or exhausts the list of  notification criteria.
callNotificationCriteriaId
up to 23 charactersSpecifies the name of the set of call notification criteria to associate with the sequence number.
description
up to 199 charactersSpecifies an optional description for the call notification criteria group.
