i found a changes for rever_uri() function . i am using carrierroute module
to route changes. so after a query destination number , a prefix is added to
Request uri and sends request. after get error first request goes to
failure route and works revert_uri() . revert_uri changes to first request
uri. There is a example above.
Client sends
: 5055066105
Servers addes prefix
: 200025055066105
after t_relay if i get error goes to failure_route[3] and work revert uri :
5055066105
in kamailio V4.2.5 it gives "200025055066105"
ALERT: <script>: Request Uri -0 05055066105
ALERT: <script>: Request Uri -1 Before revert 200025055066105
ALERT: <script>: Request Uri -2 After revert 05055066105
----- Sample Code ----------------
[switchingroute]{
//$avp(69 is prefix 2002
$rU=$_s($avp(69)$rU);
if(!cr_route("$avp(s:carrier)","$avp(s:domian)","$rU","$rU","call_id","$avp(s:route_desc)"))
{
send_reply("603", "Route bulunamadi");
exit;
}
$avp(s:host)= $rd+":"+$rp;
t_on_failure("3");
if(!t_relay()) {
xlog("L_ERR","Servis Disi");
send_reply("408", "Servis Disi");
}else{
exit;
}
return;
}
failure_route[3]{
xlog("L_ALERT","Request Uri -1 Before revert $rU");
revert_uri();
if(!cr_next_domain("$avp(s:carrier)","$avp(s:domian)","$rU","$avp(s:host)","$T_reply_code","$avp(s:domain)")){
xlog("L_ALERT","[$ci]route:bulunamadi");
exit;
}
if(!cr_route("$avp(s:carrier)","$avp(s:domian)","$rU","$rU","call_id","$avp(s:route_desc)")){

exit;
}
$rU=$_s($avp(69)$rU);
xlog("L_ALERT","Request Uri -2 after rever $rU ");
$avp(maliyet_id)=$avp(s:route_desc);
$avp(s:host)= $rd;
