Prerequisite features |
The SRI For Basic Call Routing feature performs a MAP SendRoutingInformation lookup based on the address selected by a previous execution of the Determine SRI Lookup Number Feature. The SRI request contents and destination HLR are determined by the configuration associated with the feature.
The SRI response is saved in the SendRoutingInfoRes field defined in the com.opencloud.sentinel.feature.common.sribasiccall.SRIForBasicCallRoutingSessionState Sentinel session state interface.

Session State interface
Uses the SRILookupNumber as the MSISDN for the query. If this is not set the feature continues without affecting the call.
The SendRoutingInfoRes result is stored in the SendRoutingInfoRes field defined in the com.opencloud.sentinel.feature.common.sribasiccall.SRIForBasicCallRoutingSessionState session state interface.
The IMSI from the SendRoutingInfoRes is stored in the IMSI field defined in the com.opencloud.sentinel.common.ImsiSessionState session state interface.
Configuration
The SRI For Basic Call Routing configuration includes:
| Parameters | Type | Description |
|---|---|---|
SccpOriginatingAddress |
Will be used as the TCAP Calling Party Address in dialogs initiated towards the HLR and MSC.
May be null in which case the local SCCP address configured for the platform will be used.
Example: |
|
InvokeTimeout |
Long |
SendingRoutingInformation invoke timeout in milliseconds (for example, 5000). A 0 value results in CGIN RA defaults being used. |
Map3Supported |
Boolean |
if ‘true’ will use |
HLRAddress |
HLR address for the SRI |
|
GSMSCFAddress |
Return address for responses (e.g. Sentinel address) |
|
PrePagingSupported |
Boolean |
When true sets the Pre_pagingSupported flag in the SRI |
FailOnError |
Boolean |
When true the feature will respond on error with a featureFailedToExecute to the Sentinel core, when false the feature will continue without reporting error to the core. |
