acceptCall (15)

The acceptCall message is sent by the recipient of a requestCall message to signal that they have accepted the incoming call. This completes the call signaling handshake and allows media streaming to begin.

This message is a specialized version of the appRequestAccept message, contextualized by the call's sessionId.

Core Data Types

• IxiBytes: See IxiBytes Encoding.

Payload Structure

The payload follows the structure of an AppDataMessage. The appInfo field is not required in the response.

Field	Data Type	Min	Max	Description
sessionId	IxiBytes	*	*	The unique identifier of the call session being accepted. This MUST match the sessionId from the original requestCall message.
data	IxiBytes	0	*	Optional. Contains the recipient's call parameters, such as the chosen codecs from the list offered in the requestCall.

Behavioral Notes

• Trigger: A user's client sends this message after the user clicks "accept" on an incoming call notification.
• Implementation: The client constructs an AppDataMessage payload with the call's sessionId and sends it within a SpixiMessage of type appRequestAccept.
• Sender Action: Upon receiving acceptCall, the original caller's client knows the call is connected. Both clients can then proceed to exchange media via callData messages.
