<div dir="ltr"><div><div><div>Hi,<br><br></div>First of all, changing From\To headers on proxy breaks the RFC =) So that's the initial problem of your set up I guess.<br><br></div>About your qustion, check out the wiki about failure_route:<br>

<div><br></div><div>So. I have construction Asterisk --> Kamailio --> Providers</div>
<div><br></div><div>My provisers registered with UAC modure and stored at UACREG table.</div><div><br></div><div>Problem scenario is:</div><div><br></div><div>I ring from asterisk to provider</div><div><br></div><div>Asterisk --> Kamailio --> Providers</div>
<div><br></div><div>Call from asterisk come to kamailio with </div><div>furi(Asterisk_clinet_local_number@asterisk)</div><div>turi(external_number@kamailio)</div><div><br></div><div>Then, to forward INVITE to provider that Needed I use some manipulations to choose provider (it does not matter, it is only sql_queryes to some tables), and then modify invite with this code:</div>
<div><br></div><div>#$var(prov) - my.provider.ip</div><div>#$var(trunk) - name_of_trunk </div><div><br></div><div>$rd=$var(prov);</div><div>$rp="5060";</div><div><span style="white-space:pre-wrap"> </span></div>

<div><br></div><div><br></div><div>So -after this manipulation I have write packet, that goues to my provider.</div><div><br></div><div>Then Provier sends me 407 answer and packet goes to failure_route</div><div><br></div>
<div>if (t_check_status("401|407")){</div><div> xlog("L_INFO", "Reply from provider on failure: $rs");</div><div> </div><div> if (uac_auth()){</div><div> #my query to get avp for uac</div>

<div><span style="white-space:pre-wrap"> </span></div><div><span style="white-space:pre-wrap"> </span>So After changes Before Provider answer 407 my $fU = name_of_trunk, but at failure route my fU is Asterisk_clinet_local_number and it so strange because I see this packet at TCPDUMP and it have trunkname at fU</div>
<div>Because of It I can not take from table needed vars for auth and avp`s Have 0.</div><div><br></div><div>So packet for Auth (407) goes to Asterisk (with trunkname!!!! at fU), but t must stops at kamailio and must be ralayed to provider.</div>
<div><br></div><div>So this my problem- I can not understand: Why fU at reply 407 have old parameters?</div><br><br></div></div></div>
