+# Voicemail Detection Enhancements
+
+1. **Voicemail Detection Enhancements**: You can now configure voicemail detection across providers with [`Assistant.voicemailDetection`](https://api.vapi.ai/api#:~:text=https://api.vapi.ai/api#:~:text=SessionPaginatedResponse-,Assistant,-AssistantPaginatedResponse), for example with [Vapi](https://api.vapi.ai/api#:~:text=VapiVoicemailDetectionPlan), [Google](https://api.vapi.ai/api#:~:text=GoogleVoicemailDetectionPlan), and [OpenAI](https://api.vapi.ai/api#:~:text=OpenAIVoicemailDetectionPlan).Each plan now supports a `type` property to select between:
+  - `audio`: Native audio model detection (default)
+  - `transcript`: ASR/transcript-based detection
+
+2. **Fine-tuned control**: Under each voicemail detection plan, you can configure backoff plans and beep detection timing with [`Assistant.voicemailDetection["yourVoicemailDetectionPlan"].beepMaxAwaitSeconds`](https://api.vapi.ai/api#:~:text=https://api.vapi.ai/api#:~:text=VapiVoicemailDetectionPlan) for improved voicemail handling in automated calls.

+1. **New Structured Output Endpoints**: You can now use [new APIs for structured outputs](https://docs.vapi.ai/api-reference/calls/list#:~:text=Delete%20Logs-,Structured%20Outputs,-GET) to define, extract, and manage structured data from conversations.
+
+2. **Configure Structured Output Resources**: You can now define reusable structured data extraction templates, including:
+  - **Custom JSON Schema**: Specify the exact structure and validation rules for extracted data using full JSON Schema support (objects, arrays, enums, validation constraints, and more).
+  - **Model Selection**: Choose the LLM (OpenAI, Anthropic, Google, or custom) for extraction, or provide custom system/user prompts with Liquid templating for advanced scenarios.
+  - **Context Linking**: Link structured outputs to specific workflows or assistants for context-aware extraction.
+  - **Metadata**: Track creation/update timestamps, org linkage, and provide rich descriptions for each structured output.
+
+3. **Assistant Transfer Improvements**: You can now include an optional `name` property to better identify and manage your transfer assistants.

 ### 2. Give menus time to finish before responding
 
 IVR menus often speak slowly and include longer silences than typical user speech. If your assistant responds too quickly, it may send tones before the IVR has finished listing options and there's a chance that is not ready to receive inputs.
