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.

could you please provide the LOCATION route and the Kamailio's log at level 3?
Thank you.

Hello,
I’m using Kamailio 4.4.4 with TSILO module in order to support Push Notifications used by
our voip app on Apple ios10.
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-…
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?
Thanks in advance
