### Initiating Calls

There are a few ways to create a call:

1. **Inbound Calls:** Triggered by incoming traffic from PSTN, SIP, or other sources.
2. **Outbound Calls (via Dial):** Initiated from within an existing call session using the `dial` command.
3. **Outbound Calls (via API):** Created directly by sending an API request to the Voice API.
4. **Call Queuing:** Calls can be queued and processed based on parameters such as priority, time, or custom logic.
