Hey Vitalie :)<br><br>Thanks for suggesting Lua. We are keen on Lua but does it support multi-threading. I could see this<br><a href="http://stackoverflow.com/questions/2978120/multithreading-in-lua">http://stackoverflow.com/questions/2978120/multithreading-in-lua</a><br>
<a href="http://kotisivu.dnainternet.net/askok/bin/lanes/">http://kotisivu.dnainternet.net/askok/bin/lanes/</a><br><br>But how stable is multi-threading in Lua ?<br><br>Currently, we are using python stackless for running multi-threaded IVR in FreeSWITCH but we are not happy :(<br>

Hi<br><br>We are considering writing our own module for processing IVR in C. We are considering using mod_event_socket and then modify it to consume and produce the events internally instead of passing them to the socket. Is this a good idea?<br>


<br>I know FreeSWITCH already has a mod_dialplan_xml which can use mod_curl to communicate to the outside world for I/O and DB access. But ...<br><br>1) Does XML have all the power flexibility that will be needed for powerful IVR applications? <br>


<br>2) Does mod_dialplan_xml use a separate thread for each IVR execution ? What will be the overhead of interpreting the XML ?<br><br>3) Any more ideas ?<br><br>Thanks :)<br><br clear="all">regards,<br>Anita<br><br>
