Description: SIP-INFO is a method of the Session Initiation Protocol (SIP) used to send additional information during a communication session. This protocol, which is fundamental in VoIP telephony and multimedia communication, allows users to exchange real-time data such as text messages, images, or status information without interrupting the active session. SIP-INFO is characterized by its ability to efficiently transport control information and data, making it a valuable tool for enhancing user experience in voice and video applications. Through this method, participants in a call can send and receive complementary information, facilitating interaction and collaboration. The flexibility of SIP-INFO allows its integration into various platforms and devices, making it relevant in an increasingly connected and digital world.
