[2.4.0]

[Added]

• Conference server: new parameter conference-server/call-timeout to kill all incoming calls that last longer than the defined value.
• Configuration: you can now indicate a unit (ms, s, min, h, d, m, y) along with the value for a duration parameter in the configuration file. See File Syntax for more information.
• Proxy/Router: new parameter module::Router/static-targets that lists sip addresses which will always be added to the list of contacts fetched from the registrar database when routing INVITE and MESSAGE requests.
• Proxy/NatHelper: new strategy to route requests through NATs called "flow-token" (RFC5626)
  • new parameter module::NatHelper/nat-traversal-strategy to indicate the strategy to use for routing requests through NATs (contact-correction or flow-token).
  • new parameter module::NatHelper/force-flow-token to force the use of flow-token under specific conditions ( boolean expression).
• B2BUA server: improvement of the 'sip-bridge' mode. It now enables the bridging of calls from a Flexisip-managed domain to a third-party domain but also from that third-party domain to the Flexisip domain, on a per-user level. See SIP Bridge for more information.
• Conference and B2BUA servers: new parameters b2bua-server/audio-port, b2bua-server/video-port, conference-server/audio-port and conference-server/video-port to specify which port (or range of ports) to use for RTP and RTCP traffic.

[Changed]

• Build: refactor of the build system to meet new CMake standards.
• Configuration: now throw an exception with an explicit explanatory string when a key is found several times in the configuration file.
• Proxy/PushNotification: Invite/Cancel feature is now only used for Apple voip push notifications.
• Internal: refactored software architecture (removed singletons) so you can now run several flexisip instances on the same machine.
• Proxy/NatHelper: parameter module::NatHelper/contact-verified-param is renamed module::NatHelper/contact-correction-param.
• B2BUA: custom header flexisip-bu2bua is renamed X-Flexisip-B2BUA.
• Internal: Flexisip tester can now be used without the need for installation.

[Deprecated]

• Windows push notifications: these push notifications are not handled anymore.
  • parameter module::PushNotification/windowsphone no longer has an effect.
  • parameter module::PushNotification/windowsphone-package-sid no longer has an effect.
  • parameter module::PushNotification/windowsphone-application-secret no longer has an effect.
• Proxy/registrar: parameter module::Registrar/redis-server-timeout no longer has an effect. This parameter is not really deprecated. It is not used for the moment but may be used in the future.

[Removed]

• Ubuntu 18.04: support discontinued as distribution end-of-life has exceeded (2023-05-31).
• CentOS 7: support discontinued as distribution end-of-life is scheduled for 2024-06-30.
• Debian 10: support discontinued as distribution end-of-life is scheduled for 2024-06-30.

[2.3.4]

[Added]

• Dependencies: added python3-google-auth and python3-requests to package dependencies.
• Build: added CMake variable FLEXISIP_VERSION to enable build without GIT repository.

[Changed]

• Build: disabled default configuration file generation when crosscompiling.
• flexisip_cli.py: API change, REGISTRAR_DELETE now returns an empty record instead of "Error 404" when deleting the last contact of a Record, OR when attempting to delete a contact from a non-existent Record.

[Fixed]

• Proxy: fix a crash when parsing an invalid "Contact" header value.
• Proxy/NatHelper: fix wrong "Contact" header correction in response when the proxy is first and last hop.
• Configuration: fix a crash when configuring an invalid boolean expression.
• Proxy/PushNotification: fix missing "to-tag" parameter on "110 Push Sent" when module::PushNotification is enabled and filter parameter module::PushNotification/add-to-tag-filter evaluates to true.
• Proxy/Router: fix no call is routed to callee when module::Router/fork-late and module::Router/message-fork-late are enabled.
• Proxy/PushNotification: fix several issues on the new Firebase V1 push notifications client.
• Proxy/EventLogs: fix wrong computation of event id. Previous method was sensitive to an inversion of "From" and "To" header values.
• B2BUA server: fix behavior of the B2BUA. It was erroneously trying to resume a call that was paused with a=inactive in SDP.
• Proxy/Forward: fix missing contact paths processing for mid-dialog requests intended to GRUU addresses. Fetched paths from database were not translated into Route headers before forwarding the request.
• Proxy/Router: fix Proxy does not send terminal response in case of an early cancelled call when module::Router/fork-late is on. This case could happen when a client had an offline device and/or did not have the time to answer to the INVITE request before the CANCELED request (from the caller) arrived to the Proxy.

[Deprecated]

• Proxy/EventLog: parameter event-logs/flexiapi-token is renamed event-logs/flexiapi-api-key. It still works but deprecated, please use the new name.

[2.3.3] - 2023-12-14

[Added]

• Presence: last activity date is sent with long term presence.
• B2BUA server: you can now force the usage of a specific video codec. See the video-codec config for more information.
• B2BUA server: add a configurable time limit on calls and fix a bug where calls where limited to 30 minutes. See the max-call-duration config for more information.
• B2BUA server: allow to use other transport protocol than TCP.
• B2BUA server: you can now choose the User-Agent header for outgoing B2BUA request with the user-agent config.
• Proxy/push-notification: you can now choose between a HTTP/1 or a HTTP/2 client for the generic push-notification service. See the external-push-protocol config for more information.
• [Experimental] Proxy/push-notification: you can choose to use the new Firebase v1 API to send Android push notifications. See firebase-service-accounts config for more information. Use with caution, this feature is experimental.

[Changed]

• Proxy/logs: improve Redis request logging in case of errors.
• Proxy/router: add a configuration parameter to choose database connection pool size for message persistence. See the message-database-pool-size config for more information.
• Packaging: Flexisip will create default configurations files on first install.

[Fixed]

• B2BUA server: fix a bug where Trenscrypter mode placed outgoing calls using the request address instead of the To header from the incoming call.
• Packaging: fix Systemctl warning and service restart on Rocky Linux 9 after package update.
• Proxy: fix a server hangup that occurred on TLS connection timeout.
• Proxy/push-notification: fix crashes around HTTP/2 client that occurred on iOS push notification sending.
• Proxy/http/2 client: fix a problem where frames where not sent directly after an HTTP/2 window size update.
• Proxy/registrar: fix a race condition on rapid consecutive REGISTERs that may lead to a crash.
• Proxy/router: fix bug where a 5xx response was preferred over a 6xx response for some INVITEs.
• Proxy/forward: fix a bug where stateless CANCEL could be forwarded without the Reason header.

[2.3.2] - 2023-09-07

[Fixed]

• Proxy/media-relay: fix candidates media attributes being wiped out of all INVITE responses. This buggy behaviour was introduced in 2.3.1 while attempting to handle a response with ICE candidates to an INVITE without ICE candidates.
• Proxy/registrar: fix a regression in a domain-registration scenario with "relay-reg-to-domains" enabled, where the backend server fails to route to the intermediate proxy.

[2.3.1] - 2023-08-30

[Added]

• B2BUA server: add the 'no-rtp-timeout' parameter that allows to set the delay before the call is automatically hung up because no RTP data is received.

[Fixed]

• Proxy/authentication: fix behavior differences of 'soci-password-request' according to which Soci backend is used. With SQlite backend the :authid placeholder was mandatory, which is not conform with parameter docstring, whereas it was optional with MySQL backend. It is now optional whatever the backend in use.
• Proxy/media-relay: fix bad behavior when the MediaRelay forwards an INVITE without ICE candidate and the callee send back a response with ICE candidates. In this case, the media relay didn't masquerade the connection address of the response.
• Proxy/push-notification: add support of 'google' legacy pn-type.
• Conference & B2BUA servers: remove liblinphone debug messages from standard output when '-d' command-line option isn't used.

[2.3.0] - 2023-08-21

[Added]

• Flexisip proxy: add global/tport-message-queue-size parameter to set the max number of SIP messages to be queued for writing when a socket is full.
• Flexisip proxy: add support for REGISTER requests with several Contact headers.
• Flexisip proxy: reply to OPTIONS requests with “200 Ok”. Useful to keep a connection alive by using OPTIONS requests.
• Flexisip proxy: add module::Registrar/redis-auth-user parameter to allow authentication to Redis servers via user/password.
• Conference server: add audio/video conferencing capability.
• B2BUA: forwarding of RFC2833 and SIP INFO DTMFs.
• flexisip_cli.py: add REGISTRAR_UPSERT command that allows to modify or insert any registrar binding for a given Address of Record.
• External authentication plugin: add the SNI header in order to establish TLS connections with HTTPS virtual hosts.
• Packaging for Rocky Linux 9 and Debian 12.
• [Experimental] New EventLog backend based on an HTTP REST API.

[Changed]

• Flexisip proxy: enforce compliance with RFC3261 when processing REGISTER requests. The Call-ID is no longer used as unique-id when no +sip-instance parameter has been set in the Contact-URI; the Contact-URI is used instead by using URI comparison logic as described in RFC3261 – Section 10.2.4. The CSeq value is now used to avoid replay attacks or SIP race conditions.

[2.2.5] - 2023-08-02

[Added]

• Presence server: add timestamp of last activity to the presence notification when the status of the user is 'away' or their client is no longer active.

[Fixed]

• Proxy: fix system file descriptor limit detection bug that was eventually causing Flexisip to run out of file descriptors to handle all of its connections on some OS.
• Proxy – ContactRouteInserter: increase the max size of the 'CtRtxxxxx' parameter to 512 bytes to ensure that a full domain name can be stored.
• Proxy – ExternalPushNotification: fix bad behavior when an iOS client uses legacy push parameters while registering and the 'app-id' parameter doesn't end with '.prod' or '.dev'. It caused the '$app-id' placeholder to be replaced by a truncated 'app-id'. The fix makes Flexisip assume the 'app-id' ends with '.prod' if the user agent hasn't specified the last component.

[2.2.4] - 2023-04-20

[Fixed]

• Bug in SofiaSip that causes the proxy to choose a not fully established TCP connection when it needs to send a SIP message to a user agent. That causes some SIP message losses.
• Make the proxy to answer “200 Ok” to OPTIONS requests that are directly addressed to itself.
• Crash when the “Generic Push Notifications” feature is enabled (module::PushNotification/external-push-uri) but no Firebase API key has been put in firebase-projects-api-keys parameter.
• Fix a bug that causes some PUBLISH requests that was not related to presence information to be forwarded to the presence server.

[2.2.3] - 2023-04-11

[Fixed]

• CLI: print a more explicit message when the CLI cannot connect to the server socket due to permissions.
• Pusher: allow to set a custom payload for Firebase push notifications requests, as it is for Apple.
• Presence server: ensure that capabilities of each device of a user are concatenated by union while sending a NOTIFY request to the subscriber.
• Proxy server: make the generic pusher to replace the $app-id parameter by the right value.

[2.2.2] - 2023-02-24

[Fixed]

• Issue in packaging and deployment scripts.

[2.2.1] - 2023-02-24

[Added]

• 'global/tport-message-queue-size' parameter in flexisip.conf. Allows to set the size of the message queue which is used when a SIP message cannot be sent because the socket is full.

[Changed]

• Format of --key option of ./flexisip_pusher tool. The option only takes the Firebase authentication token now.

[Fixed]

• Bug that caused the number of contacts for a given AoR to grow indefinitely when there was no '+sip.instance' parameter in the Contact-URI.
• Push notification was not sent to the second device when two devices had the same 'pn-prid' but distinct ' pn-provider'.
• Messages were not forwarded with the same order as when they were received, should 'save-fork-late-message-in-db' feature have been enabled.
• 6xx responses were not prioritized on 4xx responses when the proxy had to forward a final response to the caller.
• Compilation with ENABLE_SOCI=OFF was broken.
• Crash when the “Periodic Binding Refresh” mechanism (rfc8599) was enabled (module::PushNotification/register-wakeup-interval>=0)
• The MediaRelay let the video stream pass in one direction only when the call was in early-media.
• Flexisip depended of useless runtime libraries such as libGLEW, libX11, etc.
• The ExternalAuthentication module didn't set the SNI header when it connected on the HTTPS server.

[2.2.0] - 2022-10-28

[Added]

• Back-to-back user agent service
• module::Router/message-database-enabled parameter: allow to store the chat messages that are waiting for delivery in a SQL database instead of memory (experimental). Associated parameters: message-database-backend, message-database-connection-string.
• Filter syntax getter additions:
  • contact.uri.{user,domain,params}: get parts of the Contact-URI of the current SIP message;
  • content-type: get the full Content-type of the body as string.
• module::ExternalAuth/trusted-hosts parameter: allow to let requests coming from given IP addresses pass the ExternalAuth module. This module is provided by 'libexternal-auth' plugin.
• Make the proxy to answer to double-CRLF ping sequence (RFC5626 §4.4.1).
• Use double-CRLF ping sequence (RFC5626 §4.4.1) to maintain connections made by the domain registration feature.
• Packaging for Rocky Linux 8, Debian 11, Ubuntu 22.04 LTS.

[Changed]

• Improve the usage of iOS remote push notifications for notifying incoming calls. This is useful for home-automation applications that haven't any VoIP push notification token. In such a case, Flexisip will send several alert PNs to the application until one called device accept the call, and then, send a final alert PN to all the other devices telling that the call has been answered elsewhere. Furthermore, all the called devices receive a final PN should the caller cancel the call. Related parameters: module::PushNotification/call-remote-push-interval.
• The body of the SIP messages are hidden by default except the body of type application/sdp. This behaviour may be customized by global/show-body-for parameter that allows to modify the condition that discriminates which request should have their body displayed.

[Fixed]

• Make the MediaRelay module to handle UPDATE requests.
• Issue where a 200 Ok for REGISTER coming from an upstream server is discarded instead of being routed back the originator of the REGISTER. Only concerns user of module::Registrar/reg-on-response feature.
• Avoid push notification sending while forwarding INVITE requests with Replace header.
• Issue with domain registration digest authentication which failed because of the selection of a different SRV node between first and authenticated request.
• Add a mechanism to ensure that all devices receive an INVITE followed by a CANCEL when a caller cancel a call invitation. This is useful for iOS devices that are ringing before receiving the INVITE request because they are notified by a VoIP push notification. Thus, such devices need to receive a CANCEL request to stop ringing.

[Deprecated]

• conference-server/enable-one-to-one-chat-room parameter. Will force to true in further versions.
• Package for Debian 9.

[2.1.6] - 2023-09-22

[Fixed]

• Backport of several fixes concerning our HTTP/2 client code.

[2.1.5] - 2022-06-09

[Fixed]

• reg-on-response parameter no longer worked since Flexisip 2.1.0

[2.1.4] - 2022-05-19

[Fixed]

• Fix warning about failing SQL request on conference server starting.
• Make Flexisip to require Hiredis >= 0.14.
• Remove Sofia-SIP implementation of some functions that must be found on system.

[2.1.3] - 2022-03-18

[Fixed]

• ExternalPusher: the response to each HTTP request systematically has a delay of a few seconds when using a TCP connection instead of TLS.
• Race condition around Redis SUBSCRIBEs/UNSUBSCRIBEs that causes Flexisip to wrongly thinks that it is subscribed to some fork contexts. Finally, that causes to have end-users' device receiving push notifications for a message but no message is delivered by Flexisip once the application registers again.
• Weakness in the module replacement algorithm that causes some modules coming from plugins to be inserted in bad position in the modules list.

[2.1.2] - 2021-12-22

[Added]

• rtp_bind_address configuration parameter, which allow to choose the listening address of the media relay.
• Allow boolean expression filter to access the Contact header of the request.

[Fixed]

• Have the CMake script to install flexisip-version.h header and embed it in the RPM/DEB package.
• Crash of the proxy when using REGISTERAR_DELETE command in flexisip_cli.
• Fix problems in migration of old protobuf-encoded Registrar entries.

[2.1.1] - 2021-10-25

[Fixed]

• Fix an issue in the CPack script that caused the name of CentOS packages to not conform with CentOS format, because the distribution tag (el7, el8, etc.) was missing.

[2.1.0] - 2021-10-20

[Added]

• New Flexisip service, 'RegEvent server', available through flexisip-regevent SystemD service. The RegEvent server is in charge of responding to SIP SUBSCRIBEs for the 'reg' event as defined by RFC3680 - A Session Initiation Protocol (SIP) Event Package for Registrations. To generate the outgoing NOTIFY, it relies upon the registrar database, as setup in module::Registrar section.
• Proxy New transport URI parameter: tls-allow-missing-client-certificate=<true/false>. This allows to accept TLS connections from clients which haven't any X.509 certificate even if tls-verify-incoming has been enabled. Valid for SIPS transport only.
• Proxy Add module::DoSProtection/white-list parameter in flexisip.conf to allow packets from given IP addresses to bypass the DoS protection system.
• Proxy Add module::Authentication/realm parameter that allows to force the realm offered by the proxy to user agents during authentication (401/407 responses).
• Conference server Several factory URIs can be handled by the server.
• Push notifications New option --custom-payload for flexisip_pusher utility that allows to manually set the payload sent to push notificaiton server (Apple push only).
• Flexisip CLI Add REGISTRAR_DUMP CLI command to dump all addresses of record registered locally.
• Packaging Support of CentOS 8 and Debian 10 GNU/Linux distributions.

[Changed]

• Proxy regex operator of filter expressions in flexisip.conf now uses ECMAScript grammar from C++ specification.
• Proxy Firebase push notifications are now sent by using HTTP/2 protocol.
• Presence server Moving soci-user-with-phone-request and soci-users-with-phones-request parameters from [module::Authenticaiton] section to [presence-server].
• Conference server Conformance to 1.1 specification.
• Packaging Packaging process has entirely been reworked in order to embed Flexisip and Linphone SDK inside a single package. Thus, a given version of Flexisip is strongly bound to a specific version of Linphone SDK.

[Deprecated]

• Presence server Setting module::Authentication/soci-user-with-phone-request and module::Authentication/soci-users-with-phones-request parameters still works but will raise a warning.

[Removed]

• Proxy/Push notifications pn-silent push parameter has no more effect.
• Proxy/Push notifications Remove legacy form-uri key-value from Firebase push notification body.

[2.0.9] - 2021-08-10

[Fixed]

• Proxy Reverts the previous fix which prevents that two contacts with the same push parameters be registered for the same user. Side effects which caused some users to not receive messages or calls have been observed in production.

[2.0.8] - 2021-08-09

[Added]

• Proxy Adding 'fallback-route-filter' parameter in 'module::Router' section. This parameter allows to prevent some SIP requests to be forwarded to the fallback route when all the forked transactions have failed. The parameter expects a boolean expression as the filter parameter at the beggining of each module::* sections. The fallback route is used when the boolean expression is evaluated to true.

[Fixed]

• Proxy Prevent SIP client to registers two distinct contacts (distinct UID) which would have the same push notification parameters. That often happens when Linphone is uninstalled and installed again on an iOS device, causing the instance UID to be generated again but keeping the same push notification tokens. That causes the device to receives several push notifications for each SIP request because Flexisip assumes that each contact URI matches a distinct device. To avoid this scenario, Flexisip automatically removes the old contact URI to ensure the unicity of the push notification parameters.

[2.0.7] - 2021-07-09

[Fixed]

• Proxy Fix a bug that caused the fallback route to be used even if the forked request had succeeded.

[2.0.6] - 2021-07-07

[Fixed]

• Proxy INVITE requests was systematically forked to the fallback route (if set) independently of the status of each received response. Furthermore, the fallback destination was called alongside the real contact addresses of the called identity.

[2.0.5] - 2021-06-09

[Added]

• Flexisip CLI Add three new counters: count-basic-forks, count-call-forks and count-message-forks.

[Fixed]

• Apple push notifications Set the 'apns-push-type' header.
• Apple push notifications Correctly set the 'apns-expiration' header, basing on some parameters of module::Router (call-fork-timeout and message-delivery-timeout).
• Apple push notifications Prevent the TLS connection from blocking the main thread for more than one second while connecting.
• Android push notifications Fix typo in the name of one key in the PNR payload. ('form-uri' -> 'from-uri'). The old key will be supported until Flexisip 2.1.
• External Authentication plugin Correctly print the HTTP response from the authentication server in the log.
• External Authentication plugin Fix bug that caused the HTTP response to be matched with the bad request when several request was sent simultaneously.
• Filter parameter Fix crash on evaluation when 'contains' operator has no left-hand operand. Makes Flexisip to abort on starting otherwise.
• Flexisip CLI Fix crash with Python3 < 3.7.
• Memory usage Fix several memory leaks.
• XWiki doc generator Fix bad output syntax when bullet points are used in parameter descriptions.
• XWiki doc generator Generate documentation for the experimental modules.

[2.0.4] - 2021-03-01

[Fixed]

• Authentication Prevent password mismatch error when hashed passwords are in upper case in the user database.
• Push Notifications Prevent the PushNotification module from sending an out-of-dialog "180 Ringing" reply when an in-dialog 180 reply has already been forwarded back by the Router module.
• Apple push notifications The new HTTP/2 client now automatically close the connection with the APNS after one minute of inactivity to prevent the connection to be silently destroyed by aggressive routers. That improve PNR sending reliability.
• Android push notifications Use timeouts that has been set in the Router module settings to fill the TTL with the push notification request. See Flexisip's specification around push notifications for more information about the involved parameters.
• Media relay Fix an issue while processing a SDP without ICE containing an IPv6 connection address, and Flexisip has no IPv6 address available. Previously, an empty connection address was set by the MediaRelay module, causing a blank call. Now, the IPv4 address will be used as fallback, which will work if the network provides NAT64 service.
• Proxy server Fix several huge memory leaks. No more memory leaks issues are known on the proxy component today.
• Conference server The transport address now allows to restrict the listening interface. Before, the conference was listening on all interfaces independently of the transport host.

[Removed]

• 'pn-silent' custom Contact parameter for push notifications.

[2.0.3] - 2020-11-13

[Fixed]

• Apple push notification client: the body of HTTP/2 GOAWAY frames wasn't printed in log, which doesn't allow to know the disconnection reason.
• Fix a regression that causes to have an empty pub-gruu parameter in the Contact header of forwarded REGISTERs.
• Fix potential crash or at least memory corruption when both "route" and "default-transport" are set in the ForwardModule. The default-transport will not be applied when route is used.
• MediaRelay: fix ICE restart not being detected or notified on the offered side. This causes relay candidates to be not added in the 200 Ok, which can break RTP communication.

[2.0.2] - 2020-10-14

[Fixed]

• Fix a crash that occures when module::Registrar/reg-on-response feature is enabled. It happens when the “200 Registration successful” response is received from the backend server.

[2.0.1] - 2020-10-13

[Changed]

• Usage of HTTP2 protocol to send Apple push notification requests. No change in PushNotification module configuration required.

[Fixed]

• Crash when trying to fetch domain records from registrar DB.
• Avoid MediaRelay's channel to continuously swap between IPv6 and IPv4 during ICE connectivity checks. Indeed, this causes some connectivity checks to fail because some stun requests sent over IPv6 are answered over IPv4 and vice versa. The workaround implemented consists in locking the destination chosen by the MediaRelay's channels (when receiving a packet) for a minimum of 5 seconds. The switch to a new destination is allowed only if the previous destination has been unused over the last 5 seconds.

• Prevent “110 Push sent” response from being sent after “180 Ringing”.
• Prevent sending of multiple “110 Push sent” responses when a call is forked into several legs.
• Prevent server abort on registration with an invalid Address-of-Record.
• Crash when processing a REGISTER with an invalid Contact URI.
• Bad behaviour when receiving a REGISTER request which contains a '@' in its CallID.
• Failing authentication when the user part of the "From" URI has escaped sequences.
• Improve Firebase's push notification resilience against broken sockets.
• Remove empty 'pub-gruu' params from contact headers of OK response when module::Registrar/reg-on-response is on.
• SystemD service not restarted on package update.
• Fix MediaRelay ICE processing when the server has both IPv6 and IPv6 addresses. Previously, only ICE relay candidates with the "preferred" connectivity was offered. However, the way the "preferred" connectivity is guessed is not reliable, especially when sending the INVITE to the callee, and it can change during a call, for example when one of the parties moves from an IPv6-only LTE network to an IPv4-only network. For these reasons, it is preferable that ICE relay candidates are added for both IPv4 and IPv6.

• Fix becoming admin again after leaving and reentering a chat room.
