tsilo ts_append problem - sr-users

6 Jul 2016

Hello,

we are using tsilo to achieve mobile push notification in kamailio.

In tsilo module documentation, ts_append() function is used with the pseudo
variable “$tU” holding the username of the to-uri.

Our config looks like :

route[PUSHJOIN] {
        $var(hjoin) = 0;
        lock("$tu");
        $var(hjoin) = $sht(vtp=>join::$tu);
        $var(hstored) = $sht(vtp=>stored::$tu);
        $sht(vtp=>join::$tu) = $null;
        unlock("$tu");

        if ($var(hjoin)==0) {
                if ($var(hstored)) {
                        ts_append("location", "$tU");
                }
                return;
        }

        $var(id_index) = $(var(hjoin){s.select,0,:}{s.int});
        $var(id_label) = $(var(hjoin){s.select,1,:}{s.int});
        t_continue("$var(id_index)", "$var(id_label)",
"INVRESUME");
}

In ts_append() function code, ts_check_uri() is called on a variable holding
a username and not a URI causing the failure of the function ts_check_uri()
and resulting in ts_append() to exit. The following line is displayed in the
log: [tsilo.c:205]: ts_check_uri(): bad uri [giovanni.mele].

The function ts_store() stores in the R-URI field the username and not the
request URI. 

route[RELAY] {
        # enable additional event routes for forwarded requests
        # - serial forking, RTP relaying handling, a.s.o.
        if (is_method("INVITE|BYE|SUBSCRIBE|UPDATE")) {
                if(!t_is_set("branch_route"))
t_on_branch("MANAGE_BRANCH");
        }
        if (is_method("INVITE|SUBSCRIBE|UPDATE")) {
                if(!t_is_set("onreply_route"))
t_on_reply("MANAGE_REPLY");
        }
        if (is_method("INVITE")) {
                if(!t_is_set("failure_route"))
t_on_failure("MANAGE_FAILURE");
        }

        if (!t_relay(PROXY_IP, PROXY_PORT)) {
                sl_reply_error();
        }

        if (is_method("INVITE")) {
                ts_store();
                $sht(vtp=>stored::$tu) = 1;
                route(SENDPUSH);
        }

        exit;
}

route[INVRESUME] {
        statsd_gauge("SIPRegistrar.InviteResumed", "+1");
        lookup("location");
        t_relay(PROXY_IP, PROXY_PORT);
        ts_store();
        $sht(vtp=>stored::$tu) = 1;
}

With the command “kamcmd ts.dump” we can see the following lines:
R-URIs: {
                R-URI: giovanni.mele
                Hash: 74014921
                Transactions: {
                        Transaction: {
                                Tindex: 63704
                                Tlabel: 2105932514
                        }
                }
        }

If we try to use the ts_append() function with the pseudo variable “$tu”
holding the full to-uri address, there is no error returned by
ts_check_uri() (as this is called on a correct URI) but the transaction
corresponding to the to-uri cannot be found (maybe because the R-URI stored
by ts_store() is the username and not the full R-URI). 

How can we make things work ? By storing the full R-URI with ts_store() ?

Thx for your help

Giovanni
