I hav an issue with append branches to branch route when I need fork call to one endpoint
woth different destionations.
I use my own algorithm for call to this devices because with lookup("location")
I can not use RTPENGINE for different types of endpoints (web endoints and standart UDP
endpoints)
My alg is here:
{
sql_query("ca", "select contact from location where
username='$tU'", "ra");
xlog("L_INFO","rows: $dbr(ra=>rows) cols:
$dbr(ra=>cols)\n");
if($dbr(ra=>rows)>0){
$var(i)=0;
while($var(i)<$dbr(ra=>rows)){
xlog("L_INFO","SQL query return contact {$dbr(ra=>[$var(i),0])} for
{$tU} at step {$var(i)}\n");
if ($dbr(ra=>[$var(i),0])=~"transport=ws"){
xlog("L_INFO", "This is a Websocket call to endpoint");
sql_pvquery("ca", "select received from location where
contact='$dbr(ra=>[$var(i),0])'","$var(recieved)");
$du=$var(recieved);
xlog("L_INFO","SQL query return recieved {$var(recieved)} for {$tU}.
Destination is {$du}\n");
append_branch("sip:$tU@$(du{s.select,1,:})");
}
else
{
xlog("L_INFO", "This is a classic UDP call to endpoint");
$var(recieved)='';
sql_pvquery("ca", "select received from location where
contact='$dbr(ra=>[$var(i),0])'","$var(recieved)");
xlog("L_INFO", "SQL query return RECIEVED {$var(recieved)}");
if ($var(recieved)==0){
xlog("L_INFO", "Recieved string is EMPTY");
$du="sip:"+$(dbr(ra=>[$var(i),0]){s.select,1,@});
}
else {
xlog("L_INFO", "Recieved string is {$var(recieved)}");
$du=$var(recieved);
}
$var(UDP_contact)="sip:"+$(dbr(ra=>[$var(i),0]){s.select,1,@});
append_branch("sip:$tU@$(du{s.select,1,:})");
xlog("L_INFO","Classic Destination URI is {$dbr(ra=>[$var(i),0])}
for {$tU}}. Destination is {$du}\n");
}
$var(i) = $var(i) + 1;
}
}
else{
exit;
}
t_on_branch("1");
return;
}
}
}
branch_route[1]{
if($du=~"transport=ws"){
xlog("L_INFO","Websocket Branch is {$du} for {$tU}\n");
rtpengine_manage("internal extenal force trust-address replace-origin
replace-session-connection ICE=force RTP/SAVPF");
t_on_reply("REPLY_FROM_WS");
}
else{
xlog("L_INFO","UDP Branch is {$du)} for {$tU}\n");
rtpengine_manage("replace-origin replace-session-connection ICE=remove
RTP/AVP");
t_on_reply("MANAGE_CLASSIC_REPLY");
}
}
So as you see I choose array of devices and then set its to branches.
At the kamailio console I see output
This is output of alg that above.
I have 3 devices: 2 websocket devices and 1 udp
But when you look at dump where rtpengine make changes with packets you can see that it
runs for 4 devices and 1 and 4 devices is the same.
You can see start of every branch from words of log "Websocket Branch is" or
"UDP Branch is"
So this bug gives a mistake because some of hardphones can not handlie double INVITE and
kamilio response for this devices cancel with 200 cause because hardphone set 482 reply to
kamialio.
(you can see it reply at the log)

New subject: [kamailio] append_branch add to branch route first R_URI twice (#72)
Be aware that r-uri (request uri, represented by $ru as var) it is itself a branch. Also
$du (outbound proxy - destination uri) is associated with the $ru branch.
In the config snippet, you assign values to $du, that means you set the destination
address for the branch of r-uri ($ru). because you only use append branch, you don't
change the r-uri branch and that stays as extra branch with latest $du you set.
What you should do:
- if $var(i)==0 (the first row of the result) - set the $ru to the contact and the $du to
received value
- if $var(i)!=0 (the next rows of the result) - do append_branch() with the contact and
set the $(branch(dst_uri)[-1]) to received value
As a suggestion, you are using the string transformation to parse URI from database in
order to get domain part, etc... you better use the uri transformation, because it is
designed for this kind of need.
I am closing this here, such discussion has to be done on sr-users mailing list, follow up
there if you need further assitance.
