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>
