VAPI does support various methods for handling voice calls, but as for the specifics regarding websocket and SIP connections, as well as using your own SIP trunk, these details are not provided in the context given to me.
For call flows, typically, you would need to set up your call logic within VAPI to handle incoming and outgoing calls. This often involves registering your application's webhook URLs with VAPI so that it knows where to send call events and instructions.
Regarding the number of multiple calls you can handle in parallel, this usually depends on your service plan and the infrastructure capabilities of VAPI. It's important to check the official documentation or contact support for the most accurate and up-to-date information.
If you need more detailed information on any of these topics, please ask support for more info on this.
