Guys, this is getting a bit more intense than what the OP asked about. He wanted some information on how to use a first-aid kit, not how to perform brain surgery! :P<br><br>-MC<br><br><div class="gmail_quote">On Thu, May 13, 2010 at 1:16 PM, Phillip Jones <span dir="ltr"><<a href="mailto:pjintheusa@gmail.com">pjintheusa@gmail.com</a>></span> wrote:<br>

An ESL server controlling several FS instances has a view of everything that is going on. All calls/conferences etc. A real advantage. That is lost when two ESL servers are run in parallel. State information could be in a DB cluster - but why not have the in-process app access this directly, cutting out the middle man? <br>
<br>How does using ESL make it more scalable and more available with fewer components? I am sure you are correct - I just don't see it.<br><br><div class="gmail_quote">On Thu, May 13, 2010 at 3:15 PM, Kristian Kielhofner <span dir="ltr"><<a href="mailto:kris@kriskinc.com" target="_blank">kris@kriskinc.com</a>></span> wrote:<br>

more available with fewer components. Why not have N servers running<br>
your socket app with N servers running FreeSWITCH?<br>
<br>
OpenSIPS introduces its own issues with failover and I've yet to see<br>
DNS SRV be the reliability/scalability solution it's made out to be.<br>
