Use when building ACS calling, chat, SMS, email, Teams interop, or contact center/Job Router solutions, and other Azure Communication Services related development tasks. Not for Azure Notification Hubs (use azure-notification-hubs), Azure Web PubSub (use azure-web-pubsub), Azure SignalR Service (use azure-signalr-service), Azure AI Bot Service (use azure-bot-service).4---5# Azure Communication Services Skill67This skill provides expert guidance for Azure Communication Services. Covers troubleshooting, best practices, decision making, architecture & design patterns, limits & quotas, security, configuration, integrations & coding patterns, and deployment. It combines local quick-reference content with remote documentation fetching capabilities.89## How to Use This Skill1011> **IMPORTANT for Agent**: Use the **Category Index** below to locate relevant sections. For categories with line ranges (e.g., `L35-L120`), use `read_file` with the specified lines. For categories with file links (e.g., `[security.md](security.md)`), use `read_file` on the linked reference file1213This skill requires **network access** to fetch documentation content:14- **Preferred**: Use `mcp_microsoftdocs:microsoft_docs_fetch`. Returns Markdown.15- **Fallback**: Use `WebFetch`. Returns Markdown.1617## Category Index1819| Category | Lines | Description |20|----------|-------|-------------|21| Troubleshooting | L33-L107 | Diagnosing and fixing ACS calling, SMS, email, Teams,
