Hi everyone,

I've been trying to determine if a message was successfully delivered to a device.
Stumbled on a post from February (subject: Testing mod_sms) http://lists.freeswitch.org/pipermail/freeswitch-dev/2012-February/005619.html:

hi you can find out how to use the lists at http://lists.freeswitch.org

try latest GIT, i put in a patch to fire the events with the heder
Failed-Delivery true
if you are listening for MESSAGE events you should catch them.

I can't find any reference to Failed-Delivery in mod_sms.c neither anywhere else in the source tree. 
There is a field called Delivery-Failure, but seems to be used by other modules to indicate a failure on the response going out of freeswitch, not to freeswitch.
Was this overwritten / rolled back at some point ? 

thanks
