Tony, <br><br>Thanks for clearing this up, I was curious about the distinction myself. <br><br><div><span class="gmail_quote">On 8/31/06, <b class="gmail_sendername">Anthony Minessale</b> <<a href="mailto:anthmct@yahoo.com">

<div>Essentially the session is the high level entity that represents an outside connection and the channel is an </div>
<div>object inside the session that is a collection of the higher level components of the call.</div>
<div> </div>
<div>see <a href="http://www.freeswitch.org/docs/structswitch__core__session.html" target="_blank" onclick="return top.js.OpenExtLink(window,event,this)">http://www.freeswitch.org/docs/structswitch__core__session.html</a>
</div>
<div> </div>
<div>At this point channel is just a struct inside session that shows you things you are allowed to safely play with.</div>
<div> </div>
<div>Think of it like C++ as if channel is a class based on session as a base class.</div>
<div> </div>
<div>The switch_channel.c api has no idea what a session is and the core_session api has no idea what a channel is they</div>
<div>only know they have an opaque pointer to each other to use api calls on when the time comes.</div>
<div> </div>
<div>The session contains all the low level things like access to memory pools and the I/O routines where the channel</div>
<div>has things like channel variables and is the main entitiy that travels in the state machine and passes messages and dtmf around.</div>
<div> </div>
<div>So the short answer is that it's purely asthetic for the sake of a clean API.</div>

<br>Subject: [Freeswitch-users] What's differents with "session" and "channel"?<br><br>
<div>
<p><font face="Verdana" size="1"><span style="font-size: 9pt; font-family: Verdana;" lang="EN-US">I am confused "session" with "channel" in FreeSwitch.</span></font></p>
<p><font face="Verdana" size="1"><span style="font-size: 9pt; font-family: Verdana;" lang="EN-US">A channel is a connection which brings in a call to the FreeSwitch.</span></font><font face="Verdana" size="1"><span style="font-size: 9pt; font-family: Verdana;" lang="EN-US">
</span></font></p>
<p><font face="Verdana" size="1"><span style="font-size: 9pt; font-family: Verdana;" lang="EN-US">Once a call is established, it is named "session". </span></font></p>
<p><font face="Verdana" size="1"><span style="font-size: 9pt; font-family: Verdana;" lang="EN-US">So multi session could exist in one channel, am I right? </span></font></p>
<p><font face="Verdana" size="1"><span style="font-size: 9pt; font-family: Verdana;" lang="EN-US"> </span></font></p>
