This application provides a call prompt method, a call device, a readable storage medium, and a chip system. The method includes: enabling a call prompt mode; identifying a first audio feature of call audio received by the call device; determining a call state based on the first audio feature; and performing call prompting based on a call prompting manner corresponding to the call state.

A system of a telecommunications network that uses IP Multimedia Subsystem (IMS) network elements to screen inbound calls. A Media Resource Function (MRF) intercepts an inbound call and uses various techniques to screen the call. The MRF redirects the call to an interactive voice response (IVR) system, which prompts the caller to state the caller's name, records the caller's response, and relays it to the called subscriber, who can then decide to accept or reject the call. The system can present a random number challenge to the caller. The system can use machine learning analytics and a large language model (LLM) to analyze the response's contents, accepting the call only if it relates to a topic allowed by the subscriber, perform audio analysis to determine whether the caller sounds robotic, or detect whether the response contains other known robocall markers.

Computer program products, methods, systems, apparatus, and computing entities are provided for call control. Upon receipt of a voice call initiated by a mobile device, one or more call control rules associated with the phone number through which the voice call was received is determined, and responsive to identifying the one or more call control rules, an alternative communication session is initiated with the mobile device by transmitting a message to the mobile device including a hyperlink to initiate the alternative communication session. The voice call is then suspended and then later terminated upon determining that a user of the mobile device selects the hyperlink to initiate the alternative communication session.

Embodiments of the present application relate to the technical field of communication, and provide a video greeting playing method, system, server and storage medium. The video greeting playing method includes: in response to receiving a call transfer request indicating that a first terminal fails to call a second terminal, acquiring a type of a media channel currently accessed by the first terminal; in response to that the type of the media channel currently accessed by the first terminal is audio, performing video media negotiation with the first terminal; and in response to that the video media negotiation with the first terminal succeeds, sending a video greeting pre-recorded by the second terminal to the first terminal for the first terminal to play the video greeting.
