Sentinel SIP 4.0.0 Changelog

Session-Expires header, Min-SE header and "timer" value of the Supported header are now copied to the MRF INVITE in the Play Announcement feature. (#519194)

Fixed a bug in the SIP Play Announcement features which caused URI parameters in the configured ICSCF URI to be ignored. (#641218)

Update the Sentinel Common dependency to 4.0.0.15

Address B2BUA issue observed when a PRACK is received on the upstream leg for rel100 response after the downstream leg has already been terminated. (#206770)

The Sip Play Announcement (Early Media) feature runs twice in the MMTel-Term SIP Access Response feature script. It would queue the same response twice. If the message contains SDP, it can interact badly with the SDP Monitor and cause issues with subsequent SDP negotiation. (#359032)

Fix a bug in SequentialForkedSDPMediation feature when handling an ACK during mediation. (VOLTE-7976)

Update the Sentinel Common dependency to 4.0.0.14

Update StoreHeaderInfo to set the IsOCTerminatingDomainPresent flag to true if 'OC-Terminating-Domain' header is present. (#233441)

Update RecordTimestampsFeature to record the timestamp of an initial INVITE 180 Ringing. The timestamp is used by VolteNetworkKPI to calculate Post Dial Delay. (#195142)

Fix an issue in the B2BUA SCUR feature that allowed rounding errors to accumulate over time. When the rounding error accumulates to a full second value the next CCR will include a greater number of Used-Service-Units than granted in the previous CCA. (VOLTE-8788)

As a result of this fix the OC-Cumulative-Granted counter (present in CDRs) will report a partial second value if at some point during a session credit is invalidated.

Fix issue with parsing of P-Associated-URI, where earlier it was taking the entire value of the field eg. "<sip-uri>;param=val", vs now it would take only the part inside of angle braces (<sip uri>). (#257024)

Fix a typo in SAS bundle for 2 events in SipMidCallPlayAnnouncement feature so that the leg name is displayed in the summary as intended, and one in SipPlayAnnouncement feature so that UNABLE_TO_LINK_LEGS correctly shows the exception message if one is provided. (#257684)

Update the Sentinel Common dependency to 4.0.0.13

Update the Sentinel Common dependency to 4.0.0.12

Fix issue where post mid call announcement the passive party would receive SDP answer containing m= lines not present in the SDP offer. This could happen if the played party negotiated different media to those agreed for the original call. (VOLTE-9212)

When Normalizing numbers from national to international format, allow for the possibility that the Country Code on the output number matches the National Dial Prefix on the input number, as is commonly the case for US numbers. (VOLTE-9949)

Update the Sentinel Common dependency to 4.0.0.11

Update SDPMonitor to execute FSM on all outbound messages for a leg. Previously you could use leg.sendMessage() to send both an SDP error response and a new SDP offer in the same transaction. The offer would not be detected by the SDPMonitor feature and associate leg SDP accessors would not be updated. (VOLTE-10166)

Fixed an issue in SequentialForkedSDPMediation feature where a preconditions UPDATE arrives from calling party while updating preconditions in called party, causing an exception and leaving FSM in a bad state. (VOLTE-10150)

Add support in the leg API for querying the progress of the INVITE session setup on that leg. (VOLTE-10133)

Add the NorthAmericanNumberingPlan feature, which examines dialled numbers based on information from the normalizer to identify numbers that are within the North American numbering plan and load additional geographic information when a geographic area code is detected. (VOLTE-9962)

Update the Sentinel Common dependency to 4.0.0.9

Added a number of ServiceInformationSessionState fields containing various aggregated and extracted values for use as sources of data for Service-Specific-Info AVPs. (VOLTE-9894)

This release is built on and requires JDK 11. It requires Rhino 3.0 or later releases.

Improvements to handling of reason headers on CANCEL requests. (STLSIP-1310)

Modified handling of activities when a feature enters the waiting state. Previously all activities would be suspended and then activities that the feature is waiting on would be resumed, but this can cause issues when a feature has activity contexts from different transactions. So now activities will only be suspended if they will stay that way, activities that the feature is waiting on will never be suspended. (VOLTE-9290)

Log ICID to SAS with double quotes (STLSIP-1314) SAS requires markers to be raised with identical data for it to correlate trails. Both Clearwater and CFS raise ICID with surrounding double quotes so Sentinel is modified to do the same.

If a Reason header is present on an incoming CANCEL request, it will now be copied onto any corresponding outbound CANCEL request on the linked SIP leg. Additionally, when a feature creates a new outbound CANCEL request with Reason header, the header will now be correctly included when the message is sent. (STLSIP-1301)

Make the Sentinel SIP service handle outstanding PRACK requests as per RFC 3262 (STLSIP-1298). Outstanding PRACK requests that match acknowledged reliable provisional responses respond with a 200 response irrespective of if a session has ended.

Update the Sentinel Common dependency to 3.1.0.3

Improve MediaDescription comparison in SdpTransformerFunction so that a media description rtpmap attribute which includes an explicit channel declaration (/1) is considered equivalent to the same rtpmap attribute that implies a single channel is in use (without /1). (VOLTE-8810)

Update ChargingInstanceToCCR mapper and SipAvpCdrUtil to ensure CCR-Us and ACR-Is include Timestamps AVP based on the SipTimestampAvpPresenceMode attribute from the DetermineChargingConfigProfileTable. (VOLTE-8493)

Out-of-the-box Diameter AVPs for Ro and CDRs are now based on 3GPP Rel 12, rather than 3GPP Rel 8.13.0 as in earlier releases. Rf AVPs are Rel 12.

The Diameter Ro Resource Adaptor has been updated to the 3.1.0.x release series, enabling AVP version downgrade/upgrade between Rel 12 and older versions. The Ro Resource Adaptor can now be configured with a SLEE API version that is different to the "wire" protocol version for the OCS. Downgrading from Rel 12 is supported as far back as Rel 8.13.0. For further information refer to Diameter Resource Adaptors Changelog.

The Sentinel Registrar service has been re-written in terms of Sentinel SIP. This means 3rd Party Registration features are programmed the same way as other SIP features, simplifying development. In previous releases general 3rd Party Registration functionality was only available as part of Sentinel VoLTE and Sentinel IP-SM-GW applications. As of this release it is available in Sentinel SIP. For further information refer to Sentinel Registrar Overview and Concepts
