Hello,<br>
<br>
<tt>the problem is that lookup(location) is handling only R-URI, so
if ruri is for user XYZ and that is offline, then will return
false.<br>
<br>
Since you create many branches with avp_pushto(), other
destinations added as extra branches will be not attempted because
of lookup(location) condition.<br>
<br>
The best is to relay the call after the avp_pushto(), so you will
get two branches (or more) coming back via loopback and then you
do lookup location for each:<br>
<br>
if(src_ip!=myself)<br>
{<br>
if(avp_db_load("$ru/username","$avp(s:fork)"))<br>
{<br>
avp_pushto("$ru/username","$avp(s:fork)/g");<br>
t_relay();<br>
exit;<br>
}<br>
}<br>
<br>
if(!lookup("location")) ....<br>
<br>
Be sure you skip authentication or other checks when the requests
comes back due to such loop, using if(src_ip==myself) conditions.<br>
<br>
Cheers,<br>
Daniel<br>

<tt>Hi all,<br>
I'm using kamailio 3.1 and I have some problems with parallel
forking.<br>
I need to implement parallel forking to different users
registered on kamailio.<br>
So, when call arrives with R-URI= <a moz-do-not-send="true"
class="moz-txt-link-freetext" href="sip:003912345678@">sip:003912345678@</a><IP_server>,
I need to fork te call to (for example) 2 users: 1001 and 1001.<br>
<br>
To do that, I've created my usr_preferences table like this:<br>
<br>
</tt>
<pre>+----+------+------------------+--------+-----------+------+-------+---------------------+
|<i> id | uuid | username | domain | attribute | type | value | </i>last_modified |
+----+------+------------------+--------+-----------+------+-------+---------------------+
|<i> 1 | | </i><tt>003912345678</tt><i> | | fork | 0 | 1001 | |
</i>|<i> 2 | | </i><tt>003912345678</tt><i> | | fork | 0 | 1002 | |
</i>+----+------+------------------+--------+-----------+------+-------+---------------------+</pre>
<br>
<tt>and I've added a code to my kam.cfg like this:<br>
<br>
</tt>
<pre>if (is_method("INVITE"))
{
xlog("L_INFO", "REQUEST Invite - M=$rm RURI=$ru F=$fu T=$tu IP=$si ID=$ci\n");
if(avp_db_load("$ru/username","$avp(s:fork)"))
{
avp_pushto("$ru/username","$avp(s:fork)/g");
}
if(!lookup("location"))
{
xlog("L_INFO", "Local user offline - M=$rm RURI=$ru F=$fu T=$tu IP=$si ID=$ci\n");
sl_send_reply("404", "User Offline");
exit;
}
else
{
xlog("L_INFO", "Local user online - M=$rm RURI=$ru F=$fu T=$tu IP=$si ID=$ci\n");
t_relay();
}
}</pre>
<br>
<tt><br>
If 1001 and 1002 are registered everything works fine (1001
Ringing and 1002 ringing).<br>
If</tt><tt> only 1001</tt> <tt>registered everything works fine
(</tt><tt>1001 ringing and 1002 is offline.).</tt> <br>
<br>
<tt>But when 1002 is registered and 1001 in offline, kamailio try
to call 1001, find that it's offline ( and I get 404 User
Offline") but no call to 1002 is attempted.<br>
<br>
<br>
<br>
What's wrong ?<br>
<br>
<br>
<br>
Regards,<br>
</tt><tt><br>
