Hi all:
Have running this script on Openser 1.2.3-notls version managing forwards
this way:
route[3] {
...
t_on_failure("1");
if avp_db_load("$ru", "*") {
if (is_avp_set("$avp(s:fwdbusy)/s")) {
setflag(23);
};
...
failure_route[1] {
...
if ((isflagset(23)) && (t_check_status("486"))) {
if (avp_pushto("$ru", "$avp(s:fwdbusy)")) {
t_reply("302","Moved Temporarily");
return;
};
};
...
User A calls user B and B has fwdbusy parameter set in user preferences; if
B is busy, proxy sends 302 message back to A with contact set to
$avp(s:fwdbusy) value. This setup usually works fine. However, sometimes the
proxy shows a strange behaviour. It starts to append an arbitrary contact to
the contact header in every forwarding it does. The contact appended has
nothing to do with A or B or the uri set in the avp. The same uri is
appended in all call forwardings performed in the system. If the proxy is
restarted, the problem disappears.
Example:
SIP/2.0 302 Moved Temporarily
Via: SIP/2.0/UDP 10.100.2.254:5060;branch=z9hG4bK51461DD5
From: <sip:[email protected] <sip%[email protected]>>;tag=92DAB388-EE7
To: <sip:[email protected] <sip%[email protected]>
>;tag=880a5593aeb097bc75600b31d6e17107-78ac
Call-ID: [email protected]
CSeq: 101 INVITE
Contact: sip:[email protected] <sip%[email protected]>,
<sip:[email protected]:5060;transport=udp>;q=0
Server: OpenSER (1.2.3-notls (i386/linux))
Content-Length: 0
<sip:[email protected]:5060;transport=udp>;q=0 is added in all forwardings
done the system.
Unfortunately I have no debug info cause it happens in production
environment. I couldn't reproduce the problem in test environment. Have you
got any idea on what could make it happen?
Thanks a lot:
Fran Lizaran
