kannel sms delivery report workout

1) Add one of the following options to core group of kannel configuration. If you use mysql as dlr-storage you have to configure two more groups to associate mysql with kannel. If you use dlr-storage=internal skip step 2. If you use dlr-storage=internal the data is not tangible according to my knowledge. Also keep in mind that there are other parameters for dlr-storage which we can use to connect with other databases like postgresql

dlr-storage = internal
dlr-storage = mysql

2) If you use mysql add following two groups to kannel.conf (or to separate file and include that file). Put your database username and password to the place of [db user] and [db passwd] . Group dlr-db uses to specify the table and map the feilds together. if you configure for mysql, the message will be temporarily stored in the table until it reaches the destination.


group = mysql-connection
id = mydlr
host = localhost
username = [db user]
password = [db passwd]
database = kannel
max-connections = 1

group = dlr-db
id = mydlr
table = dlr
field-smsc = smsc
field-timestamp = ts
field-destination = destination
field-source = source
field-service = service
field-url = url
field-mask = mask
field-status = status
field-boxc-id = boxc


Thats all for kannel.conf...

3) Now you have to introduce following extra parameters to your kannel send sms url

dlr-mask=
dlr-url=


dlr-mask specifies the types of reports which kannel should generate. dlr-url specifies the url which will be called when the delivery report is received. For dlr-mask you can use one of the following mask numbers or any combination of them.

1: delivery success

2: delivery failure

4: message buffered

8: smsc submit

16: smsc reject

If you want multiple report types, you simply add the values together. For dlr-url you have to provide a url-encoded url for example
url:
http://localhost/sms/inc/deliveryReport.php?user=john&passwd=1234&type=%d&receiver=%p&reply=%A&time=%t&usr=%n&message=%b
urlencoded url:
http%3A%2F%2Flocalhost%2Fsms%2Finc%2FdeliveryReport.php%3Fuser%3Djohn%26passwd%3D1234%26type%3D%25d%26receiver%3D%25p%26reply%3D%25A%26time%3D%25t%26usr%3D%25n%26message%3D%25b

If you use php to interact with kannel you can easily generate urlencoded url using urlencode() function.


finally the resulting url is like this
http://localhost:13013/cgi-bin/sendsms?username=[kannel user]&password=[kannel passwd]&to=[to phone number]&text=[message text]&dlr-url=http%3A%2F%2Flocalhost%2Fsms%2Finc%2FdeliveryReport.php%3Fuser%3Djohn%26passwd%3D1234%26type%3D%25d%26receiver%3D%25p%26reply%3D%25A%26time%3D%25t%26usr%3D%25n%26message%3D%25b&dlr-mask=7

here I have used dlr-mask=7 so it will report following three types;
1: delivery success

2: delivery failure

4: message buffered
