Hi Peter,

The short answer is no. When NowSMS is an SMPP server, it will use the same format for the message ID in both the submit_sm_resp and the delivery report.

You appear to be referring to the issue that there are some SMPP servers which return a message ID as a hex numeric value in the submit response, but then return it as a decimal numeric value in delivery reports.

That is a quirk, and most would say well-known bug, in a particular vendor's SMPP implementation. (In fact the message ID itself is not required to be numeric at all. You will find many SMPP providers using alternative message ID formats.)

When NowSMS acts as an SMPP client, submitting messages to an upstream SMSC, if it receives a delivery report for a message ID it does not recognise, it understands this issue and tries to convert decimal to hex to re-evaluate the delivery report.

However, when NowSMS is an SMPP server, it will use the same format for the message ID in both the submit_sm_resp and the delivery report. There is no option to emulate this well-known bug in that other vendor's implementation.
