[Kamailio-Users] kamailio crashes

[Panagiotis Skoulikaritis]

Dear Marius

The scenario is as follows:

1.  A Call is placed by a sip subscriber "A"
2.  kamailio forwards the call to the asterisk server
3.  Asterisk plays an IVR message on the subscriber "A", creates a new 
call to a "virtual" number which is forwarded to the kamailio server, 
and plays an ivr to this leg as well when the call is answered, then it 
connects the two calls.
4.  Kamailio translates the "virtual" number to the pstn number of 
subscriber B


I have attached a picture of the above scenario.

The modules that are loaded are:

loadmodule "db_mysql.so"
loadmodule "mi_fifo.so"
loadmodule "mi_datagram.so"
loadmodule "sl.so"
loadmodule "tm.so"
loadmodule "rr.so"
loadmodule "pv.so"
loadmodule "maxfwd.so"
loadmodule "usrloc.so"
loadmodule "registrar.so"
loadmodule "textops.so"
loadmodule "uri_db.so"
loadmodule "siputils.so"
loadmodule "xlog.so"
loadmodule "acc.so"
loadmodule "dispatcher.so"
loadmodule "pdt.so"
loadmodule "dialplan.so"
loadmodule "siptrace.so"
loadmodule "dialog.so"
loadmodule "sqlops.so"
loadmodule "userblacklist.so"
loadmodule "htable.so"
loadmodule "uac.so"


The config that does all the routing is :

route[10] {

        xlog("alx ------- This is Route 10 -------");

        if($rU =~ "^.*%+")
        {
                xlog("alx ------- The number contains %23 ");
                $rU = $(rU{re.subst,/^(.*)%23(.*)/\1\2/});
                #$rU = $(rU{s.unescape.user}); #It changes the %23 to # !!
                xlog("alx ------- The perl  $rU ------- ");
        }

        if($rU =~ "^.*#+")
        {
                xlog("alx ------- The number contains #");
                $rU = $(rU{re.subst,/^(.*)#(.*)/\1\2/});
                #$rU = $(rU{s.unescape.user}); #It changes the %23 to # !!
                xlog("alx ------- The perl  $rU ------- ");
        }

                $var(dial_grp) = $(rd{s.select,0,.}{s.int}); # Dialplan 
group prefix for routing
                $var(num_pr) = $(rd{s.select,1,.}{s.int});  # The number

                $avp(s:cust_prefix) = $(rU{s.substr,0,$var(num_pr)});
                $rU = $(rU{s.substr,$var(num_pr),0});

                      xlog("alx ------- Translation Done. DST num=$rU

                } else {

                }
