Yes in this way it worked fine.

Good point, I'll simply leave that for now (I still have to understand
how to associate an arriving message of a dialog to an already sent
one).
BTW, which is the simpler way to print an incoming message in the
event callback function?
Here it is my new try:
------------------------------------8<-------------------------------------
#include <stdlib.h>
#include <stdio.h>
#include <sofia-sip/nua.h>
#include <sofia-sip/su_log.h>
/* This callback will be called by SIP stack to
* process incoming events
*/
void event_callback(nua_event_t event,
int status,
char const *phrase,
nua_t *nua,
nua_magic_t *magic,
nua_handle_t *nh,
nua_hmagic_t *hmagic,
sip_t const *sip,
tagi_t tags[])
{
static unsigned int count = 1;
printf ("arrived request number %d\n"
"I have received an event %s status %d %s\n",
count++, nua_event_name(event), status, phrase);
nua_handle_destroy(handle);
}
/**
* Creates a communication handle, sends an INVITE request and destroys it.
*/
int send_invite (nua_t *nua, const char* callee)
{
nua_handle_t *handle;
/* create an handle */
handle = nua_handle(nua, NULL,
SIPTAG_TO_STR(callee),
TAG_END());
if (!handle) {
fprintf(stderr, "Failed to instantiate an handle for the invite\n");
fprintf(stderr, "Maybe another instance of a sip client running on the
same port?\n");
return -1;
}
fprintf(stderr, "Sending the invite to %s...\n", callee);
nua_invite(handle,
NUTAG_MEDIA_ENABLE(0), /* disable SDP media offer
TAG_END());
nua_handle_destroy(handle);
return 0;
}
int main (int argc, char *argv[])
{
su_root_t *root;
nua_t *nua;
su_log_set_level(NULL, 9);
if (argc <= 1) {
fprintf(stderr, "Missing the destination target");
exit(1);
}
const char* callee = argv[1];
/* Initialize Sofia-SIP library and create event loop */
su_init ();
root = su_root_create (NULL);
nua = nua_create(root, /* Event loop */
event_callback, /* Callback for processing events */
NULL, /* Additional data to pass to callback */
NUTAG_URL("sip:localhost:5060"),

Anyway thanks so far Timo for your precious help.
Best regards.
