I guess it all depends on what exactly you are trying to do.<div><br></div><div>I would say that XML cURL is by far the easiest approach if you are handling simple scenarios that don&#39;t need in call interaction. ESL is the most powerful but also the most complex one. Hope that helps.</div>

The Adhearsion framework firmly takes the 3PCC approach via inbound event socket, and does a similar thing on Asterisk. We believe that to be the best way to isolate business logic from the switch.<div><br clear="all">Regards,<br>
