Chapter 5. Setting up a SMS Gateway
accepted-smsc = B
get-url = "..."
As can be seen, the smsc-id is used to identify the SMS center from which the message came. Then, the
denied-smsc-id variable is used to prevent messages originally from the other SMS center from being
sent through the other one. Finally ’sms-service’ groups are defined with accepted-smsc so that they
only accept messages from certain SMS center.
If you want to use SMS push services, requesters should then set the smsc request parameter, or
’sendsms-user’ groups should be defined like this:
group = sendsms-user
username = operator_A
password = foo
forced-smsc = A
group = sendsms-user
username = operator_B
password = bar
forced-smsc = B
Note that if your SMS centers do not set the sender phone number but rely on number transmitted, you
should set faked-sender to all ’sendsms-user’ groups.
Running SMS gateway
Using the HTTP interface to send SMS messages
After you have configured Kannel to allow the sendsms service, you can send SMS messages via HTTP,
e.g., using a WWW browser. The URL looks something like this:
http://smsbox.host.name:13013/cgi-bin/sendsms?
username=foo&password=bar&to=0123456&text=Hello+world
Thus, technically, you make an HTTP GET request. This means that all the information is stuffed into
the URL. If you want to use this often via a browser, you probably want to make an HTML form for this.
