Update the Sentinel SS7 dependency to 4.0.0.10

Fix an issue that meant the SCCOriginatingPreAnswerSessionTransfer feature would not handle the access transfer INVITE if an UPDATE transaction was already in progress. Outstanding UPDATE requests on the remote leg will receive 491 response. (VOLTE-10166)

Add support for early REFER in Conferencing, when moderator sends REFER before ACK for the INVITE transaction. (VOLTE-9938)

Fix an issue where TADS CS fallback would fail. If the PS routing fails after the SCCTADSRouting timer fires and the CSRN for CS routing is queried from the HLR then CS routing would fail. (VOLTE-10169)

Update SCCTerminatingPreAnswerSessionTransfer so that the contact address of the new access leg is correctly sent to the calling party in the INVITE/2xx response. (VOLTE-10118)

Update SCCOriginatingPreAnswerSessionTransfer to handle the case where a reliable provisional response was sent on the original PS access leg, but a PRACK was not received back before CS handover was initiated. The feature will now use the remote update by PRACK behaviour in this case, or simply generate a PRACK to the remote party if no remote update is required. (VOLTE-10132)

Update SCCOriginatingPreAnswerSessionTransfer to handle the case where a 200 response to the initial INVITE was sent on the original PS access leg, but the ACK was not received back before CS handover was initiated. The feature will now use the remote update by re-INVITE behaviour in this case, or allow the to call to be continue if no remote update is required. (VOLTE-10133)

Update SCCOriginatingPreAnswerSessionTransfer to release the original PS access leg with a BYE request if the INVITE 200 response has already been sent. (VOLTE-10165)

Update MMTelCDIV to look for oustanding UPDATE transactions from the A-Party when creating the C-Party and responding to the UPDATE (with a 491 if no response is currently pending) to allow any SDP from the C-Party to be propagated to the A-Party. (VOLTE-10168)

Update the Sentinel Common dependency to 4.0.0.10

Update the Sentinel SIP dependency to 4.0.0.11

Update the Sentinel SS7 dependency to 4.0.0.9

Update the IM-SSF dependency to 3.0.0.8

Update SCCOriginatingPreAnswerSessionTransfer to handle signalling received after a successful remote update but before the INVITE 200. (VOLTE-10021)

Update the sentinel-registrar CacheESRVCCRegistration feature to support retry of the ATCF update. The ATCF update can be retried after a configurable period, on receipt of a SIP error response from the ATCF. CacheESRVCCRegistration feature configuration has been extended with RetryAtcfUpdateOnSIPErrorDelayMilliseconds and RetryAtcfUpdateOnSIPErrorCode (VOLTE-9969)

Add configuration to Fetch TLDN to support integration with a non compliant HLR/MSC. When InvertLOCREQDigitsAddressFromNatureOfNumber is true the LOCREQ sent to the HLR will include an address in the opposite format to that specified by the Nature of Number. The value of Nature of Number is configured with feature configuration SubscriberNatureOfNumber. (VOLTE-9941)

Fix the Fetch TLDN to respect configuration specifying the desired Nature of Number of the address in the outbound LOCREQ arg. Similarly the FetchTLDN feature should respect the 'Nature of Number' in the LOCREQ result. Transforming the TLDN to international format. (VOLTE-9777)

Add configuration for the MSC Identification Number (MSCIN) to the CDMAHLRConfigProfileTable. (VOLTE-9868)

Fix an unhandled error case in Terminating Pre-Answer Access Transfer when remote update to the calling party fails because no SDP answer was received from the called party before transfer procedures were initiated. This is now handled by immediately ending the call with a 480 response. (VOLTE-9907)

When determining the Transferrable Session Set for SCC, prefer active sessions with a last-active-time for the DN over other session types, regardless of the order in which they are read from the Session Ownership table. (VOLTE-9954)

When looking up previous registration data in the ESRVCC Reregistration feature (in order to determine whether the new registration warrants the sending of a new MESSAGE to the ATCF), default to sending the MESSAGE if this lookup fails for whatever reason, so that the code is resilient to transient lookup failures. (VOLTE-9964)

In Conferencing, fix a race condition to ensure the control connection is terminated if a connection failure occurs before the Conference INFO 200OK has been processed (VOLTE-10028)

Fix feature script to play announcement on forwarding to voicemail on timeout when not charging. (VOLTE-10080)

Update the DetermineInternationalAndRoamingStatus feature to prefer to use ISO country codes for determining the international status of a call when the destination number is in the North American numbering plan. This only applies when North American numbering plan analysis is enabled. (VOLTE-9999)

Add new InternationalCallManagement feature that can play an announcement when a subscriber is making an international call. It can also bar an international call (with an optional announcement) if the subscriber did not dial the number in international format or with an international escape code. (VOLTE-10000)

Update the Sentinel Common dependency to 4.0.0.9

Update the Sentinel SIP dependency to 4.0.0.9

Update the Sentinel SS7 dependency to 4.0.0.8

Update the IM-SSF dependency to 3.0.0.6

When using the IM-SSF for charging and the Service Composition does not receive a response from the service, respond with a 500 rather than a 503. (VOLTE-9920)

When TADS is configured to end a session due to no routes available (ie. TADSEndSessionWhenNoValidRouteFound is true), and TADS is configured to use an SRI to fetch the CS routing number, SCC T-ADS now uses the configured error response code, rather than 503. (VOLTE-9881)

Update FetchTLDN feature to support extracting TLDN from TerminationList parameter IntersystemTermination. (VOLTE-9869)

Ensure SCC Terminating Pre Answer Session Transfer feature uses the correct direction 'receiver' in generated INFO request. (VOLTE-9822)

Update Prefix Barring to still apply OperatorBar rules if the user has no ODB data. (VOLTE-9811)

Update T-ADS to not cancel last routing leg on timer and to add calling party null check that can occur after endsession has removed leg. (VOLTE-9908)

Update default sip-sis-ra configuration to send 100 Trying responses for non-INVITE transactions: after 3500ms on UDP; 1000ms on TCP and other reliable transports. (VOLTE-9906)

Update the Sentinel Common dependency to 4.0.0.8

Update the Sentinel SIP dependency to 4.0.0.8

Update the Sentinel SS7 dependency to 4.0.0.7

Update the IM-SSF dependency to 3.0.0.5

Update FetchTLDN feature to check the digits fields returned in the LOCREQ response if there is no TerminationList included. (VOLTE-9791)

Update FetchTLDN feature to set TransactionCapability parameter in the LOCREQArg. This ensures we receive a TerminationList in the LOCREQResult from the HLR. (VOLTE-9751)

Fix a bug in the threshold alarm for sip-sis-inbound and sip-sis-failover. Also disable the ramp-up portion of the respective rate limiters (VOLTE-9782).

Replace 'No subscriber service data' warnings generated by MMTel features with 'FallbackToNetworkDefaultServiceConfig' statistic (VOLTE-5651).

Allow disabling reorigination-bypass when users are roaming with the always-term-reoriginate-if-served-user-is-roaming option. (VOLTE-9713)

Installs now come with a default rate limiting structure that is connected to the SIP SIS inbound_invites endpoint. The limiters are bypassed=true by default, meaning that they need to be altered (bypass=false) in order to take effect. When they are altered with bypass=false Initial INVITE requests are subject to overload control. Default values include a maximum number of activities, a maximum size for MemDB-Local, and a maximum rate of Initial INVITE requests per second. (VOLTE-9724)

Installs also come with threshold alarms, that are not activated. A minor alarm is raised when the MemDB-Local is above 70% full, and cleared when it is less than 70% full for 5 minutes. This is defined in the memdb-size-rejecting-work threshold rule. A minor alarm is raised when the number of active activities is above 70,000, and cleared when it is less than 70,000 for 5 minutes. This is defined in the active-activities-rejecting-work threshold rule. A major alarm is raised when the sip-sis-inbound rate limiter (or parent) rejects work and is cleared after 5 minutes of no work rejection. This corresponds to the sip-sis-inbound-rejecting-work threshold rule. A major alarm is raised when the sip-sis-failover rate limiter (or parent) rejects work and is cleared after 5 minutes of no work rejection. This corresponds to the sip-sis-failover-rejecting-work threshold rule. (VOLTE-9667)

Add SAS tracing for CAP messages. (VOLTE-9704)

Fix a bug where conference call state could be preserved after a conference ends, even after a SLEE restart. (VOLTE-9574)

Change ESRVCC Re-registration logic to trigger the normal ESRVCC registration flow when detecting a change in ATU-STI or in ATCF uris. This will result in a new MESSAGE to update the ATCF. (VOLTE-8998)

Changed the SIS composition on-timeout behaviour when invoking the Registrar from ignore-and-continue to terminate-processing. The SIS will no longer forward the request (based on the Request-URI) and instead send a 504 response to the received REGISTER request. Also changed the status code of the response sent on SIS trigger failure from 503 to 500. (VOLTE-9376)

Update the Sentinel Common dependency to 4.0.0.3

Fix issue where SCCProcessHandoverInsideAnchor would fail when trying to use the PlmnIdAnalyser for conference PSI comparisions using the MCC and MNC. (VOLTE-7991)

Remove a restriction for Re-INVITE based conference calls. (VOLTE-7877) The originating attempt from the moderator towards the conference factory is now able to traverse originating Application Servers. This means that once a conference is established, the conference moderator may access transfer, and the conference continue. Additionally the iFC is simplified as conferencing may be invoked using regular Terminating AS iFC. Each conference factory identity must still remain as a Public Service Identity in order to trigger the terminating MMTel AS for the call towards the conference factory (terminating unregistered). When the originating attempt towards the conference factory occurs - there will now be charging (e.g. Ro / Rf / CDRs) for that session as for any other originating attempt. The IM-SSF proxies Initial Requests without contacting the Service Control Point if the Request-URI (i.e. Conference Factory PSI) is not a phone number. Note: Moderator control of the conference is not transferred to the CS domain as this requires the so called "MSC Server Enhanced for IMS Centralised Services" that is mutually exclusive with the MSC Server invoking CAP triggers for non-roaming subscribers. Additionally the SCC-AS requires several additional capabilities to support the "MSC Server Enhanced for IMS Centralised Services".

Fix RemovePreconditionsFields counter of StripPreconditions feature in error call cases. (VOLTE-7833)

Update MMTelCDIV to use legManager.releaseLeg() rather than legManager.detachFromLeg() when re-targeting. Using detachFromLeg() affects leg state immediately and can cause subsequent features to error if the detached leg is also the triggering leg. (VOLTE-5113)

Add SAS logging to IMSIDLookup feature. (VOLTE-6020)

Update DetermineRoamingFromHLR feature to perform an ATI if a SIP response indicates the terminating user is in a CS network. A new feature script MMTelTerm_HLR_SipAccess_PartyResponse has been created to run DetermineRoamingFromHLR on initial SIP responses. On installation, if GSM is enabled this feature script will be configured to run at the SipAccess_PartyResponse:sipcall:mmtel-term: execution point. (VOLTE-6429)

Make MMTel features no-op if subscriber data indicates feature is not authorized. The default behaviour when operator data is not present is configurable (true/false). When provisioning a subscriber through REM or the REST server, all authorized flags are now mandatory. To make this new functionality work for MMTelCONF in existing installations, add the relevant SubscriberDataLookup feature to the MMTelConf_SipAcess_SubscriberCheck feature script. (VOLTE-6232, VOLTE-6254 - VOLTE-6257, VOLTE-6312)

Add a list of non-provisionable retarget URIs to the MMTelCDIV feature and XCAP provisioning service. If a subscriber tries to provision a retargeting rule with a target on the non-provisionable retargeting list, the request is denied. Before MMTelCDIV retargets a request, it checks if the new target is on the non-provisionable retargeting list. If so, the retargeting rule is ignored. (VOLTE-6217 - VOLTE-6221)

Update default Post_SipAccess_SubscriberCheck execution scripts to run RecordTimestamps feature. (VOLTE-6412)

Fix a bug in the DetermineRoamingFromHLR feature. If the feature was unable to send a MAP AnytimeInterrogation Request it would pause execution for five seconds. (VOLTE-6317)

Update DetermineRoamingFromHLRFeature to extract phone number from the SIP URI regardless of whether user=phone parameter is present. (VOLTE-6317)

Update VolteInterimCdr feature to maintain extension AVPs added to ACRs by the BaseInterimCdr feature. (VOLTE-6577)

First release in the 2.8.0.x series.

Add support for session replication and failover for MMTel and SCC sessions. This support is optional, the product can be used without the capabililty. Architecture documentation for this capability is described in Session Replication. DNS configuration to support session replication and failover is described in Non-sharded DNS configuration and SRV configuration for fail-over of sticky sessions.

In order to support session replication and failover, the External Session Tracking features have been replaced and a new Facility has been added to Rhino, the Session Ownership Facility. The External Session Tracking features have been replaced with a single feature called External Session Tracking.

A new feature, named Access Leg Tracking is responsible for SR-VCC specific tracking logic within the SCC-AS.

Features gain support for session replication in a near transparent manner through the new Rhino 2.6.1 Key/Value Store. Software changes to enable session replication have been performed underneath existing APIs. For standard or "out of the box" features, this meant migrating API calls from SipSession.get/setAttribute to Sentinel Session state CMP fields. SipSession.get/setAttribute API still exist and function as they did previously, i.e. do not replicate. Custom features should use Session State, i.e. CMP APIs for their state variables.

Additional semantics and annotations for CMP fields have been added to Rhino. For details please refer to CMP Field Enhancements within Rhino 2.6.1 documentation.

Support for replicated SIP Dialogs has been added to the SIP-SIS. For details please refer to SIP Session Replication

Add support for CDMA traffic in O-SDS and T-SDS (Reorigination) scenarios and in T-ADS delivery to CS. See CDMA and SIP support for SCC for a description of the architecture, CDMAFetchTLDN for a description of the T-ADS functionality, and CDMA Reorigination Service for a description of the reorigination service.
