here is patch for sms level dlrs for wap push. Note that receiving one does not mean that the phone has understand the push, only that it has received it. You need confirmed push if you want a guaranteed delivery (and a phone supporting it, of course). Or an application level protocol having acks of its own.
Here smsbox is sending dlr to pi. This means that you must define smsbox to get push dlrs.
In addition of dlr-url and dlr-mask, you must define smsbox id and ppg service name.
