SIP Dialogs

Dialogs in SIP are not separate elements, but are inherently built on transactional processes. They play a crucial role in organizing ongoing conversations between two or more participants. A SIP conversation is essentially a series of back-and-forth messages that together constitute a session, such as a call or multimedia conference. Understanding the concept of SIP conversations is essential for developers working with real-time communications applications.

Dialog Interface

A dialog can be likened to a continuous conversation you have with someone over time. Just as you don't reintroduce yourself with every sentence, dialogs allow SIP entities to exchange messages within a session without having to renegotiate terms each time.
