loadmodule “modules/exec/exec.so”
loadmodule “modules/sl/sl.so”

route{

1. for testing purposes, simply okay all REGISTERs

if (method==”REGISTER”) {
log(“REGISTER”);
sl_send_reply(“200”, “ok”);
break;
};

1. first dump the message to a file using cat command

exec_msg(“printenv SRCIP > /tmp/exectest.txt; cat >> /tmp/exectest.txt”);

1. and then rewrite URI using external utility
2. note that the last echo command trashes input parameter

if (exec_dset(“echo sip:[email protected];echo sip:[email protected];echo>/dev/null”)) {
sl_send_reply(“300”, “Redirect”);
} else {
sl_reply_error();
log(1, “alas, rewriting failed\n”);
};
}
