Hello Guys, I've been getting delivery reports for quite some time now and until recently didn't know that UNDELIV could have different levels. I just noticed error levels from Err:000 to Err:011, Err:019, Err:255. I've guessed a few like Err:000 is a successful delivery. Can I have an explain of the others; pray tell.

Hi,

Those codes depend completely on your SMSC connection.

In other words, there is no standard for what those error codes mean.

If NowSMS is generating the error because an upstream SMPP connection is rejecting the message (you would see the errors in the SMSOUT-yyyymmdd.LOG), then this is the SMPP error code.

If the upstream SMSC provider is generating the error, then they have their own logic for what the error code means. It might be available in documentation from your provider.

If you can explain more about your outbound SMSC connection, and whether or not the delivery reports match up with errors in the SMSOUT-yyyymmdd.LOG ... then I might be able to help provide more information.

However, it is also very possible that these error codes are specific to your provider ... and that I won't have any additional information.

What kind of information will you be needing about my outbound connection? The delivery reports are ok when they come in, however, I get a message "UNDELIVD" delivery report and I don't know why it expired, so I thought the "Err: 255" will explain it to me in more detail, was it undelivered because the phone was switched off, or the number didn't exist any more or some other reason unknown to me?

As I said. There is no standard for these error codes.

If you tell me what type of outbound SMSC connection you are using, then I might be able to provide some guidance.

Or I might not ... because there is no standard for these error codes, and they could be specific to your SMS provider.

What information do I need about your outbound connection?

Any information would be helpful.

For example, is it SMPP, a GSM modem, other?

Do you see entries in the SMSOUT-yyyymmdd.LOG that also correspond to these errors? If you do, then the error code you are seeing is an SMPP error code.

All my outbound connections are SMPP connections.
The delivery reports I see are from the
SMSIN-yyyymmdd.LOG and it's a something like this.
Below are delivered sms and undelivered sms reports from the smsin-yyyymmdd.log file. Notice the err:000 and err:255 values.

I'm sorry, but I don't know what more I can tell you.

These values are service provider specific.

If you do not see entries in the SMSOUT-yyyymmdd.LOG (not SMSIN-yyyymmdd.LOG), then the messages are not being generated by NowSMS, they are being generated by your SMS provider (or another SMS provider upstream from your provider).
