Re: [SR-Users] R: serial forking calls using TSILO

Hi, please find below what you requested. @Daniel: yes, I did ts_store() after relaying for both hops, but for the second call which should call account2, $ru is overwritten to account1 after t_continue @Federico: as you requested, here is my route[LOCATION] and please the attached Kamailio log. # USER location service route[LOCATION] #!ifdef WITH_SPEEDDIAL # search for short dialing - 2-digit extension if($rU=~"^[0-9][0-9]$") if(sd_lookup("speed_dial")) route(SIPOUT); #!endif #!ifdef WITH_ALIASDB # search in DB-based aliases if(alias_db_lookup("dbaliases")) route(SIPOUT); #!endif #!ifdef WITH_FORK if($rU == "9999") route(FORK); #!endif #!ifdef WITH_PDT xdbg("before pdt $rU\n"); #prefix2domain("0", "1"); xdbg("after pdt $rU\n"); #!endif #Check if domains match if($fd != $rd) xdbg("From domain $fd does not match request uri domain $rd\n"); send_reply("488", "Not Accetable Here"); exit; #$rd = $td $avp(oexten) = $rU; if (!lookup("location")) $var(rc) = $rc; t_newtran(); switch ($var(rc)) case -1: case -3: xlog("L_ALERT","ALERT: User not found\n"); if (isflagset(FLT_ASTERISK_TRY)) # Try calling with PUSH KIT send_reply("404", "Not Found"); else # User not found, check if is an app based on uri prefix, then call it with pushkit if($(rUs.substr,0,6)=="007001") xlog("L_ALERT","ALERT: Trying calling $ru with PUSUH KIT\n"); # device token check missing route(SUSPEND); route(SENDPUSH); else setflag(FLT_ASTERISK_TRY); route(ASTERISK); exit; case -2: send_reply("405", "Method Not Allowed"); exit; # when routing via usrloc, log the missed calls also if (is_method("INVITE")) setflag(FLT_ACCMISSED); route(RELAY); route(STORETRAN); exit; route[STORETRAN] ts_store(); $sht(vtp=>stored::$rU) = 1; xlog("L_ALERT", "stored transaction [$T(id_index):$T(id_label)] $fU => $rU\n"); Thanks to both, Regards, T. *Da:* sr-users [mailto:sr-users-bounces@lists.sip-router.org &lt;sr-users-bounces(a)lists.sip-router.org&gt;] *Per conto di *Federico Cabiddu *Inviato:* domenica 22 gennaio 2017 16:24 *A:* Kamailio (SER) - Users Mailing List &lt;sr-users(a)lists.sip-router.org&gt; *Oggetto:* Re: [SR-Users] serial forking calls using TSILO Hi, could you please provide the LOCATION route and the Kamailio's log at level 3?

So far, everything works fine: Kamailio can get an incoming call, suspend it, then send push notification with an external script, receive a new app registration and then call it after resuming the invite. To do so, thanks to Mr, Cabiddu, I used all the functions described here *http://www.kamailio.org/events/2015-KamailioWorld/Day2/20-Federico.Cabiddu-Kamailio-In-A-Mobile-World.pdf* <http://www.kamailio.org/events/2015-KamailioWorld/Day2/20-Federico.Cabiddu-Kamailio-In-A-Mobile-World.pdf> Right now, I would like to support serial forking calls using push notification because it was already supported with legacy voip. To do so, I used failure_route function where, after getting the call destinations and setting them into an avp, I set the new SIP request uri $ru. Here is my failure_route: failure_route[MANAGE_FAILURE] route(NATMANAGE); if (t_is_canceled()) exit; #!ifdef WITH_BLOCK3XX # block call redirect based on 3xx replies. if (t_check_status("3[0-9][0-9]")) t_reply("404","Not found"); exit; #!endif if (is_avp_set("$avp(group_members_db)")) $ru ="sip:"+$avp(group_members_db)+"@"+$fd; $avp(group_members_db) = $null; route(LOCATION); exit; I am troubleshooting this scenario and this is what I see: 1) Kamailio receives incoming call 2) Suspend it 3) Send Push notification to account1 4) Kamailio receives account1 registration -> INVRESUME route is now called 5) Then call account1 6) Nobody answers the call 7) failure_route[MANAGE_FAILURE] is now called -> set $ru with next sipaccount: account2 8) suspend invite 9) send push notification to account2 10) account2 sends its sip registration -> INVRESUME route is now called 11) Kamailio calls account1 instead of account2 -> this is my issue On step 10: despite account2 is registered, I checked it using “kamctl ul show”, the second call is forwarded all'account1 and not to account2. I also checked the TSILO logs and everything seems ok. Here is the logs: First call: suspended transaction [53945:1648394094] asterisk => account1 htable key value [53945:1648394094] resuming trasaction [53945:1648394094] account1 53945:1648394094) second call: suspended transaction [53945:1648394094] asterisk => account2 htable key value [53945:1648394094] resuming trasaction [53945:1648394094] account2 53945:1648394094) In order to find out the issue I put some xlogs, printing $ru value: what I see is the $ru value is set correctly on failure_route but as soon as the t_continue is called, the ru overwritten back to account1 Can anyone address me to find out the solution?
