Parsing Delivery Receipt Issue #105

Open gruntday opened 9 years ago

gruntday commented 9 years ago

Hello,

Need help regarding below error

com.cloudhopper.smpp.util.DeliveryReceiptException: Unable to find [sub] field o r empty value in delivery receipt message

Delivery Receipt Parse Message works well with other SMSCs but when tried to connect to a new SMSC connection we are facing above exception while parsing the DLR String

DeliveryReceipt.parseShortMessage(dlrStr, DateTimeZone.UTC);

Appreciate your support

Your new SMSC sends you wrong DeliveryReceipt, either force them to fix it, or work around it (make your own DeliveryReceipt.parseShortMessage, or just alter the shortMessage you pass into it).

I concur your new SMSC vendor is returning invalid delivery receipts. Ask them what specifications they are following? The "sub" part for SMPP v3.3 receipts is pretty well defined in the specs.

An alternative (if they support it) is to not parse the text and rely purely on SMPP 3.4 optional parameters to fetch delivery receipt info. You can find out if they support optional parameters for that info and then skip trying to parse the text of the message for it.
