Hello,
haven't looked at error message, but if you call sleep() after
t_suspend(), then you don't gain any benefits, because you still block
the worker process, so you could just do sleep and relay.
If you want to resume execution of an invite after 5 seconds, without
blocking a worker for those 5 seconds, then see:
https://www.kamailio.org/docs/modules/stable/modules/async.html#async.f.asy…
Cheers,
Daniel

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:

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

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
