Migration from 4.0.x to 4.1.0


What is new in 4.1.0

OpenSIPS Interfaces

Provisioning Interface

  • A new core Provisioning Interface (PI) framework, migrating the provisioning logic previously hosted by the pi_http module into the core. The framework is now transport-independent and driven by the PI XML schema, while pi_http remains responsible solely for HTTP transport and command parsing. Existing behavior is fully preserved, while future transport modules can reuse the same core provisioning functionality.

OpenSIPS Core

B2B_LOGIC module

  • The b2b_bridge command receives a new flag, provmedia-extra-headers that allows you to pass the same headers as for the client when doing a bridge.

B2B_SDP_DEMUX module

  • A new parameter, pending_wait_timeout, was added to control how much we should wait for an ongoing SDP negociation to finish before handling a new client-side operation

DIALOG module

JSON module

  • added support for boolean value serialization
    • new $json_true and $json_false static values, assignable to $json() objects
    • new core {i.bool} transformation, for concise conversion of integer variables to JSON boolean values

PROTO_WS module

  • the new allowed_origins parameter allows you to filter origins allowed to communicate with the server.

PROTO_WSS module

  • the new allowed_origins parameter allows you to filter origins allowed to communicate with the server.

  • Two new variables, $rtp_relay_caller and $rtp_relay_callee were added to simplify flags provisioning for caller/callee.
  • The $rtp_relay_ctx variable has been enhanced with a new node parameter, used to specify and/or retrieve the node that has been used for that session.

RTPENGINE module

  • A new function has been added, rtpengine_rollback() that can be used to rollback to a previous checkpoint the state of the (remote) RTPEngine session.
