Description: SIP (Session Initiation Protocol) dialog refers to a series of messages exchanged between two endpoints in a network that use this protocol to establish, modify, and terminate communication sessions. SIP is a signaling protocol primarily used to manage voice and video calls over the Internet, enabling the creation of real-time multimedia sessions. This protocol is fundamental in VoIP (Voice over Internet Protocol) telephony and unified communication applications, as it allows devices and applications to communicate effectively with each other. SIP messages include requests and responses that contain information about the session, such as the addresses of the participants, the types of media to be used, and encoding parameters. The flexibility of SIP allows its use in various contexts, from simple voice calls to complex video conferences, making it an essential component in modern communication infrastructure.
