[Freeswitch-users] Best way to implement real-time ivr from mysql

[Avi Marcus]

I haven't heard of any lua sql issues.. I'd keep looking into that.
Otherwise, I'm pretty happy with the flexibility and performance afforded to
me by xml_curl (running nginx + php5-fpm. run mysql tuner and increase
cache, also...).
I have a php class with a bit of abstraction for XML and dialplan functions
(but nothing specific for IVR). You can find it at:
