You can probably use xhttp module but you will need to extract the GET 
variables from the URL. You can also an external program to send a 
MESSAGE via SIP (ie sipsak) or write your own interface script that sits 
between Kannel and  Kamailio;

check |uac_req_send() from the UAC module.

check |http_query()||| from the utils module;

http_query() again but you can also write your own function in Perl or 
LUA that interacts with the Kannel.
