 # Changelog

+## 2026-04-14 - 1.25.2 - fix(proxy-engine)
+improve inbound SIP routing diagnostics and enrich leg media state reporting
+
+- Extract inbound called numbers from DID-related SIP headers when the request URI contains a provider account username.
+- Emit detailed sip_unhandled diagnostics for inbound route misses, missing devices, and RTP allocation failures.
+- Include codec, RTP port, remote media, and metadata in leg state change events and preserve those fields in runtime status/history views.
+- Match hostname-based providers against resolved inbound source IPs to accept provider traffic sent from resolved addresses.
+- Invalidate cached TTS WAV metadata across engine restarts and vendor the kokoro-tts crate via a local patch.
+
+## 2026-04-14 - 1.25.1 - fix(proxy-engine)
+respect explicit inbound route targets and store voicemail in the configured mailbox
+
+- Prevent inbound routes with an explicit empty target list from ringing arbitrary registered devices by distinguishing omitted targets from empty targets.
+- Route unrouted or no-target inbound calls to voicemail with a generated unrouted greeting instead of falling back to random devices.
+- Pass voicemail box identifiers through proxy events and runtime handling so recordings are saved and indexed under the correct mailbox instead of always using default.
+
+## 2026-04-14 - 1.25.0 - feat(proxy-engine)
+add live TTS streaming interactions and incoming number range support
+
+- add a new start_tts_interaction command and bridge API to begin IVR or leg interactions before full TTS rendering completes
+- stream synthesized TTS chunks into the mixer with cancellation handling so prompts can stop cleanly on digit match, leg removal, or shutdown
+- extract PCM-to-mixer frame conversion for reusable live prompt processing
+- extend routing pattern matching to support numeric number ranges like start..end, including + prefixed values
+- add incomingNumbers config typing and frontend config update support for single, range, and regex number modes
+
+## 2026-04-14 - 1.24.0 - feat(routing)
+require explicit inbound DID routes and normalize SIP identities for provider-based number matching
+
+- Inbound route resolution now returns no match unless a configured inbound route explicitly matches the provider and called number.
+- Normalized routing identities were added for SIP/TEL URIs so inbound DIDs and outbound dialed numbers match consistently across provider-specific formats.
+- Call handling and incoming call events now use normalized numbers, improving routing accuracy for shared trunk providers.
+- Route configuration docs and the web route editor were updated to support explicit inbound DID ownership, voicemail fallback, and IVR selection.
+- Mixer RTP handling was enhanced to better support variable packet durations, timestamp-based gap fill, and non-blocking output drop reporting.
+
+## 2026-04-14 - 1.23.0 - feat(runtime)
+refactor runtime state and proxy event handling for typed WebRTC linking and shared status models
+
+- extract proxy event handling into dedicated runtime modules for status tracking and WebRTC session-to-call linking
+- introduce shared typed proxy event and status interfaces used by both backend and web UI
+- update web UI server initialization to use structured options and await async config save hooks
+- simplify browser signaling by routing WebRTC offer/ICE handling through frontend-to-Rust integration
+- align device status rendering with the new address/port fields in dashboard views
+
+## 2026-04-12 - 1.22.0 - feat(proxy-engine)
+add on-demand TTS caching for voicemail and IVR prompts
+
+- Route inbound calls directly to configured IVR menus and track them with a dedicated IVR call state
+- Generate voicemail greetings and IVR menu prompts inside the Rust proxy engine on demand instead of precomputing prompts in TypeScript
+- Add cacheable TTS output with sidecar metadata and enable Kokoro CMUdict support for improved prompt generation
+- Extend proxy configuration to include voiceboxes and IVR menus, and update documentation to reflect Kokoro-only prompt generation
+
+## 2026-04-11 - 1.21.0 - feat(providers)
+replace provider creation modal with a guided multi-step setup flow
+
+- Adds a stepper-based provider creation flow with provider type selection, connection, credentials, advanced settings, and review steps.
+- Applies built-in templates for Sipgate and O2/Alice from the selected provider type instead of separate add actions.
+- Adds a final review step with generated provider ID preview and duplicate ID collision handling before saving.
+
+## 2026-04-11 - 1.20.5 - fix(readme)
+improve architecture and call flow documentation with Mermaid diagrams
+
+- Replace ASCII architecture and audio pipeline diagrams with Mermaid diagrams for better readability
+- Document the WebRTC browser call setup sequence, including offer handling and session-to-call linking
+

+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify

+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,

+# Kokoro TTS的rust推理实现
+
+[Kokoro](https://github.com/hexgrad/kokoro)
+
+> **Kokoro**是具有8200万参数的开放式TTS型号。
+> 尽管具有轻巧的体系结构，但它的质量与大型型号相当，同时更快，更具成本效益。使用Apache许可的权重，可以将Kokoro部署从生产环境到个人项目的任何地方。
+
+
+## 概述
+
+本项目包含幾个示例脚本，展示了如何使用Kokoro库进行语音合成。这些示例展示了如何直接合成语音和通过流式合成来处理更长的文本。
+
+## 前置条件
+
+- Rust编程语言
+- Tokio异步运行时
+- Rodio音频处理和播放的库（可选）
+- 下载模型资源，在這裡可以找到[1.0模型](https://github.com/mzdk100/kokoro/releases/tag/V1.0)和[1.1模型](https://github.com/mzdk100/kokoro/releases/tag/V1.1)
+
+## 特点
+- 跨平台，可以轻松在Windows、Mac OS上构建，也可以轻松交叉编译到安卓和iOS。
+- 离线推理，不依赖网络。
+- 足够轻量级，有不同尺寸的模型可以选择（最小的模型仅88M）。
+- 发音人多样化，跨越多国语言。
+
+## 使用方法
+
+1. 运行示例，克隆或下载本项目到本地。在项目根目录下运行：
+    ```shell
+    cargo run --example synth_directly_v10
+    cargo run --example synth_directly_v11
+    ```
+2. 集成到自己的项目中：
+    ```shell
+    cargo add kokoro-tts
+    ```
+3. Linux依赖项
+    ```shell
+    sudo apt install libasound2-dev
+    ```
+参考[examples](examples)文件夹中的示例代码进行开发。
+
+
+## 许可证
+
+本项目采用Apache-2.0许可证。请查看项目中的LICENSE文件了解更多信息。
+
+## 注意
+
+- 请确保在运行示例之前已经正确加载了模型和语音数据。
+- 示例中的语音合成参数（如语音名称、文本内容、速度等）仅作为示例，实际使用时请根据需要进行调整。
+
+## 贡献
+
+如果您有任何改进意见或想要贡献代码，请随时提交Pull Request或创建Issue。
+
+## 免责声明
+
+本项目中的示例代码仅用于演示目的。在使用本项目中的代码时，请确保遵守相关法律法规和社会主义核心价值观。开发者不对因使用本项目中的代码而导致的任何后果负责。
