Abstract
A method for providing a stateless Session Interface Protocol (SIP) back to back user agent (B2BUA) comprising receiving a SIP message and determining if the SIP message is a SIP request. The SIP request further comprises a request to create an original SIP dialog or a request for an existing SIP dialog. Method further comprises determining if the SIP message is a SIP response.
