Key Takeaways
- AMI is a TCP text protocol on port 5038. It's not REST, not GraphQL, not WebSocket. It's a persistent TCP connection that sends and receives key-value pairs separated by CRLF. Understanding this prevents a lot of confusion when building integrations.
- manager.conf controls everything. Each AMI user gets specific permissions (read/write) for subsystems like call, agent, system, and reporting. Never give a dashboard user write permissions it doesn't need.
- Originate is the most powerful Action. It lets you programmatically place calls -- click-to-dial, automated callbacks, predictive dialing integrations. But it's also the most dangerous if misconfigured, because bad Originate loops can flood your Asterisk with channels.
- Event streams are the real power of AMI. Subscribe to events like Newchannel, Hangup, AgentConnect, and QueueMemberStatus to build real-time dashboards. VICIdial itself is built on top of these same events.
- Lock down AMI in production. Restrict by IP in manager.conf, use a non-default port, put it behind a firewall, and never expose port 5038 to the public internet. AMI gives full control of your PBX -- treat it like root access.
