<h1><a name="chan_sipTransactionSupportProprosal-Introduction"></a>1. Introduction</h1>
<p>SIP is a transactional protocol. Asterisk's chan_sip has no transaction concept of a transaction layer. Developers have spent countless hours providing workarounds for bugs caused by this situation. In fact, more hours have been spent trying to work around the issue than it would take to actually implement a transaction layer for chan_sip. This document outlines how a transaction layer can be added to chan_sip with a relatively minimal amount of change to existing code.</p>
