| This package implements the main protocol abstractions that are defined by the SIP RFC 3261. |
| These include the following main ones: |
| <ul> |
| <li>SIPServerTransaction -- an implementation of the Server Transaction State Machine (Chapter 17 of RFC 3261). |
| <li>SIPClientTransaction -- an implementation of the Client Transction State Machine (Chapter 17 of RFC 3261). |
| <li>SIPDialog -- an implementation of the SIP Dialog ( Chapter 11 of RFC 3261 ). |
| </ul> |
| |
| SIPTransactionStack is the container that holds references to these protocol objects. |
