[SR-Users] problem with relaying after t_susped() and t_continue()

[Uri Shacked]

I have a problem when using t_suspend() and t_continue().

Let's say I would like to have a 5 sec delay before relaying an INVITE.

For example the following code:



*                route[MYROUTE] {*

*                                t_newtran();*

*                                if (is_method("INVITE")) {*

*                                                t_reply("100", "Trying");*

*                                                t_reply("180", "In
Queue");*

*                                                $sht(a=>$ci::t_index) =
$T(id_index);*

*                                                $sht(a=>$ci::t_label) =
$T(id_label);*

*                                                $sht(a=>$ci::t_suspended)
= 1;*

*                                                xlog("L_WARN","SUSPENDING
t_index = $sht(a=>$ci::t_index) and t_label = $sht(a=>$ci::t_label)");*

*                                                t_suspend();*

*                                                sleep(5);*

*                                                if (t_is_canceled()) drop;*

*                                                $sht(a=>$ci::t_suspended)
= 0;*

*
t_continue("$avp(t_index)","$avp(t_label)","1");*

*                                }*

*                                route(RELAY);*

*                                exit;*

*                }*



*                route[1] {*

*                                xlog("L_WARN","After transaction
continue\n");*

*                                route(RELAY);*

*                                exit;*

*                }*



When using this code, I get the following error:

Mar  9 16:49:32 mysip /usr/local/sbin/kamailio[5260]: WARNING: <script>:
After transaction continue

Mar  9 16:49:32 mysip /usr/local/sbin/kamailio[5260]: ERROR: <core>

Mar  9 16:49:32 mysip /usr/local/sbin/kamailio[5260]: ERROR: tm [ut.h:319]:

[t_lookup.c:1481]: t_unref(): tm: t_unref: REQ_ERR DELAYED should have been
caught much earlier for 0x7fd4e727a468: 27 (hex 1b)



If I try to t_continue() without any route:

t_continue("$avp(t_index)","$avp(t_label)","");

The call is working great and the following error pops up:

Mar  9 17:10:36 mysip /usr/local/sbin/kamailio[5830]: ERROR: tmx
[tmx_mod.c:635]: w_t_continue(): empty action lists in route block []



Am I doing something wrong?



My other question is regarding CANCEL.

Let's assume I suspended the INVITE and in these 5 sec I received CANCEL
for it.

Is there a short and elegant way to remove the transaction from suspension?

For now I do:



*                if (is_method("CANCEL")) {*

*                                if (t_check_trans()) {*

*
if($sht(a=>$ci::t_suspended) == 1) {*

*
t_continue("$sht(a=>$ci::t_index)","$sht(a=>$ci::t_label)","");*

*
xlog("L_WARN","After transaction continue\n");*

*                                                }*

*                                                route(RELAY);*

*                                }*

*                                exit;*

*                }*



Thanks,

Uri
