Hi:<br> I caught the failure again with logs enabled. First of all, I've realized that I made a mistake explaining the issue before. There is no problem with forward busy at all as I said. The problem appears with forward on no answer only, so this is the part of the script to take into account:<br>
<br>route[3] {<br>...<br>t_on_failure("1");<br>...<br> # forward on no answer<br> if (is_avp_set("$avp(s:fwdnoanswer)/s")) {<br> if ($ru==$avp(s:fwdnoanswer)) {<br> sl_send_reply("603", "Decline");<br>
return;<br> };<br> setflag(24);<br> };<br>...<br>}<br><br>failure_route[1] {<br> if ((isflagset(24)) && (t_check_status("408"))) {<br> xlog("L_NOTICE", "Fwdnoanswer: $avp(s:fwdnoanswer) \n");<br>
if (avp_pushto("$ru", "$avp(s:fwdnoanswer)")) {<br> avp_print();<br> t_reply("302","Moved Temporarily");<br> return;<br>
};<br> };<br> };<br>...<br>} <br><br> So, for example, user 20173 calls user 20346 which has a fwd to 20559. After ring timeout expires, the proxy sends back to user 20173 a 302 response. In the contact header appears 20559 and another uri appended:<br>
Contact: <a href="mailto:sip%3A20559@domain.com">sip:20559@domain.com</a>, <sip:066012...@10.100.2.254:5060;transport=udp>;q=0<br><br> This uri is included along all the forwardings on no answer performed in the system.<br>
<br> Looking at the log, there is no trace of such uri in the avp list: <br> openser[11278]: Fwdnoanswer: <a href="mailto:sip%3A20559@domain.com">sip:20559@domain.com</a><br> ...<br> openser[11278]: INFO:avpops:print_avp: p=0xb57356a8, flags=0x0083<br>

<br> That time there was a correct forward no answer to this number, but t_relay got an error after cancelling. Probably it is related with later issues when forwarding.<br> <br> Regards:<br> Francisco<br>

<br>
First of all, maybe it will be a good idea to upgrade to OpenSIPS 1.5.1 - along the versions many bugs were fixed and 1.2 is a really old one.<br>
<br>
Have you tried to place an xlog and print the fwdbusy avp just before the avp_pushto() ?<br>
<br>
Regards,<br>

Hi all:<br>
Have running this script on Openser 1.2.3-notls version managing forwards this way:<br>
<br>
route[3] {<br>
...<br>
t_on_failure("1");<br>
if avp_db_load("$ru", "*") {<br>
if (is_avp_set("$avp(s:fwdbusy)/s")) {<br>
setflag(23);<br>
};<br>
...<br>
<br>
failure_route[1] {<br>
...<br>
if ((isflagset(23)) && (t_check_status("486"))) {<br>
if (avp_pushto("$ru", "$avp(s:fwdbusy)")) {<br>
t_reply("302","Moved Temporarily");<br>
return;<br>
};<br>
};<br>
...<br>
<br>
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.<br>

<sip:030410@10.172.0.254:5060;transport=udp>;q=0 is added in all forwardings done the system.<br>
<br>
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?<br>
<br>
Thanks a lot:<br>
