Dear all,
My name is Andi and this is my first post here. I hope I'm doing this
correctly.
I have a question about Kannel that I hope one of you can help me with.
Basically, I'm not quite sure yet on the common practices on handling the
delivery report (DLR) on Kannel.
I believe I've configured the mysql DLR external storage correctly by
inserting the appropriate entries on the config file. When I push an SMS by
using the http command
(http://xxx.xxx.xxx.xxx:yyyyy/cgi-bin/sendsms?username=xxx&password=xxx&from=xxx&to=xxx&text=xxx&dlr-mask=31&dlr-url=xxx),
I could see that a DLR entry is inserted into the database along with the
timestamp, status, etc.
Based on what I've read on the documentation and discussion on the internet,
I assume that when the SMSC has delivered the SMS successfully, Kannel will
do an http request to the dlr-url that I supplied (for example:
http://xx.xx.xx.xx/cgi/dlrHandling.php?smsc-id=%i&status=%d&answer=%A&to=%P&from=%p&ts=%t).
Then on the script, I would have to write my own code to manually process
the DLR individually and do other required tasks such as deleting the DLR
entry and others.
My questions:
1. Is this the common practice on handling the DLR and confirming that the
recipients have received the SMS? Am I doing this correctly by processing
the DLR entry manually? Is there any other way (more efficient way) of doing
this?
2. Why does the timestamp only consist of 2 digit number? Is my database
definition wrong? (I used VARCHAR(40) as stated on the example)
3. Is using the timestamp and the "to" number is enough to uniquely identify
which DLR that I want to process? Because what happens when there is a same
phone number having the same timestamp? Is there a unique ID for each DLR
that I should use instead of relying on the ts and the phone number?
I would appreciate any help or hints that any of you can give me.
Many thanks and best regards,
-Andi
