[Freeswitch-users] event BACKGROUND too late in ORIGINATEscenario?

[UV]

Thanks, Michael!
Your advise seemed to be a workaround to most events although not all
(missing some new, init and few others).

I'll update to the newest version as soon as there's a fix for the win32
build (doesn't work for me either). 

Btw, Will that little race fixing allow me to correlate the BGPAI JOB-UUID
to these missing events? It's not that I don't get those events - I just
don't know what request initiated them...
 
Cheers,
UV

You can set your own unique id reference as a variable to the  
originate using the {my_uuid=1234567ABCD} syntax and then track all  
events off that variable that should be included on every event.

http://wiki.freeswitch.org/wiki/Freeswitch_IVR_Originate

Also, we just fixed a little race that might have allowed you to get  
events before you got the background uuid so you probably want to  
update to most recent code.
