Hello,
I'm using kamailio 3.0 with mediaproxy and I want to cancel calls if I have no
mediaproxy relay connected to my mediaproxy dispatcher.
In my request route I'm checking if "use_media_proxy()" is returning me a
positive result and it's working fine :
use_media_proxy();
if($rc < 0) {
sl_send_reply("480","Temporarily Unavailable");
exit;
}
But I'm also want check in my onreply_route If I still have an active relay because I
need to rewrite the sdp in the 200/OK reply.
My problem is that I don't know how to end the transaction, I have tried :
if (is_method("INVITE") && status == "200") {
#!ifdef WITH_MEDIA_PROXY
use_media_proxy();
if($rc < 0) {
xlog("L_ERR", "invite reply error $rc \n");
dlg_bye("all");
}
#!endif
}
and also :
if (is_method("INVITE") && status == "200") {
#!ifdef WITH_MEDIA_PROXY
use_media_proxy();
if($rc < 0) {
xlog("L_ERR", "invite reply error $rc \n");
drop();
}
#!endif
}
In both case I'm seeing in my log file that use_media_proxy() returned me -1, but the
reply is routed to the caller ...
Any idea on how I can cancel my call in the onreply_route ?
Also, I don't know if it's a good thing to make a second call to
"use_media_proxy" in the onreply_route, mediaproxy module couldn't reply me
with a different relay address if I have multiple mediaproxy relay?
Regards,

Hello,
do you have
#!KAMAILIO
as first line in config file? This is required only for kamailio 3.0,
next versions has the feature of dropping replies by default.
Cheers,
Daniel

Sorry for the late reply, I was a little busy by something else.

Yes I have #!KAMAILIO at the beginning of my kamailio.cfg.
Also, someone notided me that it could be a better idea to do a proper
dialog establishment and try to end it after that, for example with
dlg_bye("all");
So I think I will try to use something like :
#!ifdef WITH_MEDIA_PROXY
if (is_method("INVITE") && status == "200") {
use_media_proxy();
if($rc < 0) {
xlog("L_ERR", "invite reply error,
use_media_proxy() failed with $rc \n");
if (dlg_get("$ci", "$ft", "$tt"))
{
xlog("L_DBG", "ending a new
dialog\n");
dlg_bye("all");
}
}
}
#!endif
Anyone has ever tried something like that ?
Thanks,

You will send the BYE before the 200ok is sent to caller, so it will get
rejected most probably.

The t_reply("480","Temporarily Unavailable"); send a 480 reply to the

But it also send CANCEL to the callee, which is too late because the
callee have already sent his 200OK.
I'm trying to do the same thing with the dlg_bye("callee"); but I'm
having a problem here too, the following route :

}
generate me that error :
Dec 3 15:49:06 uServer-SIP /usr/local/sbin/kamailio[10084]: ERROR:
dialog [dlg_req_within.c:105]: no contact available
Dec 3 15:49:06 uServer-SIP /usr/local/sbin/kamailio[10084]: ERROR:
dialog [dlg_req_within.c:246]: failed to create dlg_t
I think I have set correctly my dialog flag in my "route {}" route
because if I comment the "setflag" line I have a dialog not found error
instead.
For information, dlg_bye("caller") doesn't give me that error message
and send a bye request to the caller (which like you have said, isn't
what I'm looking for).
I digged a little in the source code of the contact module but I haven't
found why my dlg_cell only contain the caller contact ... I will try to
investigate further this weekend.
Thanks again for your time,
Nikita

Actually I was using the TM onreply route. Since I have switched to the
default onreply_route I'm able to drop the 200OK, thank you for the clue.

the dialog structure is not fully completed,
since callee contact comes
in 200 OK, still it is not yet handled by dialog module, so that's why
you get error when trying to send BYE to callee.
