In SIP (Session Initiation Protocol), which is used for initiating, maintaining, and terminating real-time sessions that include voice, video and messaging applications, the INVITE message is used to initiate a call or session. The INVITE message can include a variety of information, including the caller's and callee's SIP URIs, which can resemble email addresses. This is because SIP addresses use a user@domain format, similar to email addresses, allowing for easier identification and communication between parties. The other options, such as OK, BYE, and a non-existent "great" message, serve different purposes in the SIP protocol and are not used for initiating a session with an email-like address.
