Call Types

Four Ways to Connect

Landline supports multiple call types to match real-world ATC coordination needs.

Direct Call

Ring-based communication between two positions. The recipient can accept or reject the incoming call.

Override

Immediate connection without ringing. Used for urgent coordination that requires instant two-way communication.

Monitor

One-way audio listening. Perfect for training supervision and quality assurance without interruption.

Conference

Multi-participant audio rooms. Multiple controllers can join the same conversation simultaneously.

Authentication

Secure VATSIM Login

OAuth-based authentication through VATSIM Connect ensures only verified controllers access the coordination system. Select your facility and position to join the network.
