I'm trying to pass a variable back to the Kamailio script from the Kamailio module.�Let's say that my module is called "random" and it exports the function:

static int do_this(struct sip_msg *msg, char* _information);

- I pass some "_param1" and "_param2" parameters to this function from Kamailio script:

(Kamailio script code)

loadmodule "random.so"

modparam("random", "_param1", "www.host.com")

modparam("random", "_param2", 8877)

- "_information" is the content I get back from the function.

Reading _param1 and _param2 from the function of the module is pretty�straight�forward. In order to write the "_information" variable and�being�able to read from Kamailio script :

pv_spec_t* dst;

pv_value_t val;

val.rs.s = content;

val.rs.len = strlen(content);

val.flags = PV_VAL_STR;

dst = (pv_spec_t *) _information;

dst->setf(msg, &dst->pvp, (int)EQ_T, &val);

From Kamailio script I can do:

(Kamailio script code)

xlog("L_INFO","Calling do_this()\n");

$var(result) = do_this("$var(response)");

xlog("L_INFO","Returning do_this(). result=$var(result). uri=$var(response)\n");

And works fine.

Now, I was wondering If I can have the _information parameter as this :

(Kamailio script code)

loadmodule "random.so"

modparam("random", "_param1", "www.host.com")

modparam("random", "_param2", 8877)

modparam("random", "_information", $(response))

Changing the interface of the function as:

static int do_this(struct sip_msg *msg);

Calling from the kamailio script as this:

(Kamailio script code)

xlog("L_INFO","Calling do_this()\n");

$var(result) = do_this();

xlog("L_INFO","Returning do_this(). result=$var(result). uri=$var(response)\n");

But it doesn't work.

Anyone is welcome to provide insight.
