What is sip late media?

SIP late media refers to the practice in Voice over IP (VoIP) communications where media streams (audio, video) are initiated after the signaling has been established, rather than simultaneously. This approach allows for features like early media, where announcements or prompts can be played to the caller while the call setup is still in progress. It can enhance user experience by providing information or options before the call is fully connected. SIP late media is commonly used in applications like call centers or interactive voice response (IVR) systems.
