[Freeswitch-users] Questions on Building an application for FreeSWITCH

Wed May 26 14:56:08 PDT 2010

Hi,

Will incorporate some threading into the example I am working on for you.

The outbound event socket method is very similar to the dialogic
environment, I know how you felt though, but by starting small(like
just even answering a call) gets you moving pretty quick. Freeswitch
is lots of fun to work with, and the guys on here are very
supportive!!
