I would like to run Vapi Agents throw evaluation testing. And to do it I want to use WebSocket and text based communication. I've seen that is possible to [send and receive audio via websocket](https://docs.vapi.ai/calls/websocket-transport). And I have a question if it's possible to send and receive text messages? And how can I implement them.

Hi ivanprog00, How can I assist you today with Vapi's services or integrations? If you're looking to build a real-time chat interface or need help with API configurations, let me know. I'm here to help you navigate through our [streaming](https://docs.vapi.ai/chat/streaming) and [non-streaming](https://docs.vapi.ai/chat/non-streaming) chat documentation or any other feature you're working with.

Hello, Streaming chat is working for our Evaluation tests at the moment. But we would like to work with chats same as with call. It would be great if it would be possible to create a call, and using websocket communicate with Vapi AI agent with text messages.

Hey, I see you're looking to set up text-based communication with the Vapi AI agent through websockets for calls. Currently, our streaming chat is functioning for evaluation tests, but I understand you'd like a similar setup for calls. While this isn't fully implemented yet, I’ll pass your feedback on to the team for future consideration.
