Hello Henk.

Thank you for your rapid answer.

About the "DeliveryConfirmation". I changed the number format and now it´s working.

Hello Florian,

The 'IsRead' column is not used by Diafaan SMS Server, this field was used by previous versions of our software and it was preserved to keep the database layout backward compatible.

Delivery confirmation does not always work. Some mobile operators do not support status updates and do not send a delivery confirmation back to the modem. Another reason why the status code does not change could be that the number format of the 'To address' of the message does not match with the number format of the status update. For instance, when you send a message to number '0123456789' and the status update comes from number '+44123456789', Diafaan SMS Server won't be able to match the message with the status update. It is usually best to use only numbers in International number format with Diafaan SMS Server.

Regards, Henk

I am wondering for what the column "IsRead" stands for. If the message was successfully sent, only the "IsSent" value changed to "true" but "IsRead" always are "false"

At the gateway advanced properties under "SMS" the "DeliveryConfirmation" is set to "true". But at the "MessageLog" table, the status code never changed from 200 to 201.
