Hi everybody,
Actually I modify the simpleua example to manage Early message.
So when I received a message I construct a 183 response like a 180. It's works well but the method, used, does not generate a Contact header in message.
So I trying to add it like this :
/* * Initially send 183 response. * * The very first response to an INVITE must be created with * pjsip_inv_initial_answer(). Subsequent responses to the same * transaction MUST use pjsip_inv_answer(). */ status = pjsip_inv_initial_answer(g_inv, rdata, 183, NULL, NULL, &tdata); PJ_ASSERT_RETURN(status == PJ_SUCCESS, PJ_TRUE);
hsubject = pjsip_generic_string_hdr_create(tdata->pool, &name, &value); pjsip_msg_add_hdr(tdata->msg, (pjsip_hdr*) hsubject);
/* Send the 183 response. */ status = pjsip_inv_send_msg(g_inv, tdata); PJ_ASSERT_RETURN(status == PJ_SUCCESS, PJ_TRUE);
/* Local Contact. */ puts("get contact by pj_gethostip"); if (pj_gethostip(AF, &hostaddr2) != PJ_SUCCESS) { app_perror(THIS_FILE, "Unable to retrieve local host IP", status); } puts("Stock it in hostaddr2"); pj_sockaddr_print(&hostaddr2, hostip2, sizeof(hostip2), 2);
puts("construct l_uri"); pj_ansi_sprintf(l_uri, "<sip:B2BUA@%s:%d>", hostip2, SIP_PORT); puts("l_uri"); puts(l_uri);
puts("store to local_contact2"); local_contact2 = pj_str(l_uri);
puts("Contactname"); puts(Contactname.ptr);
puts("Generate hcontact2"); hcontact2 = pjsip_generic_string_hdr_create(tdata->pool, &Contactname, &local_contact2);
puts("Add in Tdata"); pjsip_msg_add_hdr(tdata->msg, (pjsip_hdr*) hcontact2);
puts("end");
/* * Managed Prack request after sending 183. */ status = pjsip_100rel_on_rx_prack( g_inv, rdata); if (status != PJ_SUCCESS) { app_perror(THIS_FILE, "Problems in managing PRACK", status); return 1; }
There is not error message, but in result no header contact is added.
I don't uderstand why.
Thanks in advance for your help.
C?dric.
