Hello,
this topic was last discussed here:
http://lists.iptel.org/pipermail/serusers/2005-May/019551.html
last few days i was trying to apply juha's move() function with almost no success to
0.9.3 stable branch.
i added such code to my ser.cfg:
onreply_route[1] {
xlog("L_NOTICE", "Reply status %rs: Reason %rr\n");
if (t_check_status("30[12]")) {
xlog("L_NOTICE", "We got a 30[12]!!!!!\n");
t_move(); # custom function by juha
#t_reply();
};
}
and modified move() code like this:
inline static int move(struct sip_msg* _m, char *_foo, char *_bar)
{
//struct sip_msg* reply;
regmatch_t pmatch[2];
struct hdr_field hf;
contact_t* first;
regex_t contact_re;
// What is it? didn't find anywere.
//reply = _m->final_reply;
// MOD HERE
if (!_m) {
LOG(L_ERR, "move(): No reply found\n");
return -1;
}
LOG(L_ERR, "move(): unparsed part of reply: %s\n", _m->unparsed);
// FIXME: where to put this? initialisation?
// MOD HERE
regcomp(&contact_re, "^Contact:(.*)$", REG_EXTENDED|REG_NEWLINE);
if ( ( regexec(&contact_re, _m->unparsed, 2, &(pmatch[0]), 0) != 0) ||
(pmatch[1].rm_so == -1)) {
LOG(L_ERR, "move(): No Contact header found\n");
return -1;
}
hf.type = HDR_CONTACT;
hf.name.len = 0;
hf.body.len = pmatch[1].rm_eo - pmatch[1].rm_so - 1;
hf.body.s = &(_m->unparsed[pmatch[1].rm_so]);
hf.len = hf.body.len + 2;
hf.parsed = NULL;
hf.next = NULL;
// this prints out redirected contact
LOG(L_ERR, "hf.body: '%.*s'\n", hf.body.len, hf.body.s);
if (parse_contact(&hf) < 0) {
LOG(L_ERR, "move(): Error while parsing Contact\n");
goto failure;
}
if (((contact_body_t*)hf.parsed)->star == 1) {
LOG(L_ERR, "move(): Contact is *\n");
goto failure;
}
first = ((contact_body_t*)hf.parsed)->contacts;
if (first) {
// MOD HERE
if (append_branch(_m, first->uri.s, first->uri.len, 0, 0,
Q_UNSPECIFIED) == 1) {
goto success;
} else {
LOG(L_ERR, "move(): Appending branch failed\n");
}
} else {
LOG(L_ERR, "move(): No contacts in Contact header\n");
}
failure:
if (hf.parsed) {
free_contact((contact_body_t**)(&(hf.parsed)));
}
return -1;
success:
free_contact((contact_body_t**)(&(hf.parsed)));
return 1;
}
it seems that t_move succeeds(), contact gets parsed and append_branch() gets execuded.
But then, nothing happens. 302 is replied back to call originator. It is function
build_res_buf_from_sip_res is called() which builds 302 message back to call originator..
It seems that after getting contact from 302 message, INVITE sould be generatated somehow.
I suspect that i am passing wrong message to append_branch, but i didn't found how to
access INVITE from tm module while in onreply_route[].
Can anybody with deeper ser knowledge help?
