kannel: send to a different port

to send to a different port, include udh variable in the request string

udh=%06%05%04%2D%BF%32%D5

* 06 means "hey read the following 6 bytes"
* 05 is the format for numbers, in this case hexadecimal numbers
* 04 will tell the UDH that each port is represented using 4 character
* 0B84 is the destination port in hexadecimal, 2948 (decimal representation)
* 23F0 is the source port in hexadecimal, 9200 (decimal representation) or 23F0 (hexadecimal representation).
