**>Guys,
**>Any of you have successfully configured kannel to deal with A# charging? A#
charging is a method where we only need to connect from one user account to
SMSC then when we submit MT we add n digit behind our shortcode/shornumber, for
example I have 1234 as my shortcode, when a subscriber request content which
will be charged $2, then I will add 123402 (the 02 is the A#) then send it back
to the SMSC. I hope this explanation clear enough, what configuration needed
here? Please help me. Any reply is highly appreciated.

Scenario:
User with MSISDN of +85290009999 creates an SMS with the following
content:
add 2 3 5
and then sends it to shortcode 1234. You receive the SMS and
perform the addition, 2 + 3 + 5, and send back "Answer: 10"
using the origination address of 123402 which results in a
charge of $2 on the user's SMS charges ($2 charge requires
Mobile Network Operator to support your request for
MT billing services).
1) In the kannel.conf, have a section that accepts all MO SMS and
HTTP_POST them to your application for processing:
group = sms-service
name = smsc2myappl
keyword = default
omit-empty = true
max-messages = 0
send-sender = true
catch-all = true
post-url = "http://host.domain/addition.cgi";
2) In your application, expect Kannel to do an HTTP_POST with the
entire content of the SMS. You can retrieve the MSISDN number
of the mobile subscriber by looking at the X-Kannel-From
HTTP header. The "addition.cgi" program will get something like
this from Kannel:
POST /addition.cg HTTP/1.0
Host: host.domain:80
X-Kannel-From: 85290009999
X-Kannel-To: 1234
Content-Type: text/plain
Content-Length: 9
add 2 3 5
3) Parse the SMS to see what keyword/service the mobile subscriber
was requesting from you.
4) Perform the service on behave of the mobile subscriber. In this
case, you add 2 + 3 + 5.
5) Send the results to the mobile subscriber via an MT SMS
that is HTTP_POST'ed to Kannel's smsbox with the origination
address to be your short code + charge:
POST /cgi-bin/sendsms HTTP/1.0
X-Kannel-From: 123402
X-Kannel-To: +85290009999
X-Kannel-Username: foo
X-Kannel-Password: bar
Content-Type: text/plain
Content-Length: 10
Answer: 10
You are done.
See ya...
