[Freeswitch-users] Lua session originate - freeswitch crash

Wed Apr 13 17:05:43 MSD 2011

I'm sort of in the same boat... I've been working on a project completely in
LUA - using mod_lcr / mod_nibblebill etc - and another contributor wrote to
migrate to ESL... Not that I'm against a challenge - just disappointed I
spent so much time writing the LUA script to now have to convert to ESL.

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.
