[Freeswitch-users] IVR Architecture

[Anita Hall]

Hey Vitalie :)

Thanks for suggesting Lua. We are keen on Lua but does it support
multi-threading. I could see this
http://stackoverflow.com/questions/2978120/multithreading-in-lua
http://kotisivu.dnainternet.net/askok/bin/lanes/

But how stable is multi-threading in Lua ?

Currently, we are using python stackless for running multi-threaded IVR in
FreeSWITCH but we are not happy :(

regards,
Anita
