# How can I make a call using the SDK?

## A quick developer guide to initiate outbound calls through the FreJun SDK using virtual numbers and destination numbers with the makeCall() method.

FreJun SDK allows developers to programmatically trigger outbound calls directly from their applications without switching interfaces. Using a simple function, you can connect any destination number with your FreJun virtual number and start conversations instantly. This is ideal for CRM click-to-call, sales automation, and support workflows.

Once the SDK is initialized in your application, initiating a call requires only two parameters — the number you want to dial and the virtual number from which the call should originate. The process is lightweight, secure, and designed for real-time communication use cases.

Once initialized, call `makeCall({ destinationNumber, virtualNumber })` to start an outgoing call.
