[Freeswitch-users] Lua session originate - freeswitch crash

[Eric Beard]

Thanks Anthony,

I will update to latest.  I last did a pull about 2 weeks ago, FreeSWITCH Version 1.0.head (git-8c5586b 2011-04-01 14-22-43 -0500).

If I shouldn't be doing this in this script, then what is the recommended way to originate an outbound IVR call?

My current production application uses Microsoft Speech Server to send outbound customer service calls, with a B2BUA I wrote to communicate with terminators.  I'm switching my B2BUA out for FreeSwitch, and it's working great.  But if possible I'd like to remove MSS from the equation altogether.

Lua looks like a good way to control the call workflow.  Should I be using ESL from an external application instead?

Thanks for your time,

1) You are not running the latest GIT.  Your scripts works fine on my
development box.
2) the originate method is deprecated.  you can just do
     local new_session =
freeswitch.Session("sofia/gateway/affinity/17277762768", session);
3) In either case you should not be doing what you do in this script
because the whole time you are playing the file to new_session the
original session is blocked not reading or writing any audio.
