v0.3.0

Fixed

• honour 423 Min-Expires on REGISTER (#62)

v0.2.5

Fixed

• report presented certificate names bare (#60)

v0.2.4

Added

• [breaking] implement SIP over TLS: Transport::Tls (RFC 3261 §26.2),
  a new tls cargo feature, certificate verification against the account's
  SIP domain (RFC 5922 §7.3) with optional SHA-256 pinning via TlsPolicy,
  and a typed CertFailure / UntrustedCertificate error surface
  (tls_error).

  This ships in the 0.2.x line by deliberate maintainer decision, so it is
  not a major-version bump — but it is not additive either. It carries three
  source-breaking changes, and cargo treats 0.2.x -> 0.2.y as compatible,
  so anything depending on "0.2" picks these up on a routine
  cargo update:

  • Transport gained a new variant, Transport::Tls. An exhaustive
    match on Transport in consumer code stops compiling — add an arm
    for Tls.
  • Transport is now #[non_exhaustive], so that match also needs a
    wildcard arm. This is deliberately bundled into the same release as
    the variant above: it is the last time adding a transport breaks a
    consumer. Every future variant is additive.
  • SipAccount gained a new field, tls_policy: TlsPolicy. Constructing
    the struct with a literal stops compiling — add
    tls_policy: TlsPolicy::default() (or your chosen policy).
    Deserialized configs are unaffected: the field is #[serde(default)],
    so no stored config file needs to change.

v0.2.3

Fixed

• advertise the real transport on calls, not just REGISTER (#56)

v0.2.2

Added

• implement SIP over TCP (#54)

v0.2.1

Added

• send 100 Trying and 180 Ringing for inbound calls (#51)

v0.2.0

Added

• [breaking] Opus SDP negotiation with pinned re-offers (#49)

v0.1.2

Added

• expose Call::peer_uri for attended Refer-To target
• attended call transfer via REFER + Replaces (RFC 3891)

v0.1.1

Added

• blind call transfer via REFER (RFC 3515) (#45)

Added

• blind call transfer (RFC 3515): Call::blind_transfer sends an in-dialog
  REFER with Refer-To; transfer-progress NOTIFYs (a message/sipfrag
  status line) arrive on Call::inbound_requests and are parsed with
  parse_sipfrag_status / is_final_sipfrag. Inbound REFER / NOTIFY now
  route to the owning Call instead of being auto-answered.

v0.1.0

Added

• [breaking] in-house SIP engine, full call lifecycle (#43)
