Application Port Addressing is encoded into the User Defined Headers (UDH) part of an SMS. Kannel does not have the capability to generate a UDH with a user-defined application port address. But, you can still use Kannel to send SMS with UDH that were hand-coded by you. Create the UDH and then use the cgi parameter "udh=..." or the HTTP optional header parameter "X-Kannel-UDH" when communicating with Kannel's smsbox. For example, you want this SMS to be sent to the 16bit application port 1581 and you want the source port to be 3456. Your UDH would look like --> 06050415813456. This decodes to: 06 - SMSC control Parameter 05 - Application port addressing scheme, 16 bit address 04 - Length (in bytes) of the source and destination addresses 1581 - Destination port (in network byte order) 3456 - Originator port (in network byte order) Then, your communication with the smsbox would look like: HTTP_GET: GET /cgi-bin/sendsms?username=foo&password=bar&to=some_phone_num&udh=06050415813456&text=hello HTTP/1.0 HTTP_POST: POST /cgi-bin/sendsms HTTP/1.0 X-Kannel-Username: foo X-Kannel-Password: bar X-Kannel-To: some_phone_num X-Kannel-UDH: 06050415813456 Content-Type: text/plain Content-Length: 5 hello See ya... d.c.
