This technique has worked on 2G gsm nets.  3G and 4G, it's more carrier selective.  For a given message TEXT (not the address#), prefix the msg string with one of either,

111
-or-
*noti#

E.g.  111Hello World -or- *noti#Hello World
(Fido in Canada supports/ed 111, T-Mobile supports/ed *noti#)

I don’t think SIP MESSAGEs have a response/ack. I know that our provider doesn’t send anything except the 200 OK when we send a message, and that doesn’t mean it actually made it to the device. As far as I know there is no way to know if and when the device gets the actual message without the device responding with another message back through the via chain.

Subject: [Freeswitch-users] mod_sms delivery failure

 

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
