<font size="-1"><font face="Courier New, Courier, monospace">Just
some additional information. I've been reading up on variables,
<br>
script-operations, etc, and I cant find any(simple) way to cause
<br>
what I call a "roll-over" timer. <br>
That is, setting the timer(C) between the different
serial-forked <br>
targets low, but keeping a normal timer c for non-serial forked<br>
scenarios, and the last target in a serial fork.<br>
<br>
Also, even though I am a complete n00b when it comes to the
opensips<br>
source, I got the _parallell_ forking to work, by hacking
serialize.c<br>
and making sure that it doesnt completly bail out if the
q-values are<br>
the same. <br>
This will most certainly cause a lot of unnecessary sorting
which the<br>
old logic in the lcr-module was able to avoid, if I understood
the <br>
docs properly. <br>
But at least now my call to serialize_branches() doesnt fail.<br>
<br>
if (branch.s == 0) {<br>
LM_DBG("nothing to do - all same q!\n");<br>
// return 0; // This causes parallell fork to fail<br>
}<br>

<br>
Serialforking does work even though I cant figure out(trying
the rtfm-concept)<br>
how I can reduce the "timer C" for only the serial-forking
scenario, which<br>
I was capable of doing with the lcr module....but now
Parallell forking doesnt<br>
work anymore :-(<br>
<br>
I changed my script to:<br>
--------------------------<br>
lookup("location", "m");<br>
switch ($retcode)<br>
{<br>
case 1:<br>
log(2, "(lab2) - Contact found in location server,
rerouting.\n");<br>
if (!serialize_branches(0))<br>
{<br>
log(1, "(lab2) - Unable to load contacts for serial
forking\n");<br>
t_reply("500", "Server Internal Error (Serial fork)");<br>
exit;<br>
}<br>
if ( !next_branches() )<br>
{<br>
t_reply("509", "Serial fork error");<br>
exit;<br>
}<br>
return(1);<br>
---------------------------<br>
<br>
But when my to UA's register with the SAME q-value, I get
failure in next_branches().<br>

-------------------<br>
Concerning the timer issue, I suppose I could fiddle with the
normal fr_inv_timer, <br>
but since I only want to reduce it from its default of 180s, I
would have to find <br>
out wether (serial) forking will occur, and these functions
doesnt seem to give me <br>
that information.<br>
<br>
What I am doing wrong, with regards breaking normal parallell
fork, I havent go <br>
a clue, and I hope you can help!<br>

<pre wrap="">Hi Taiso,
the load_contacts() and next_contact() are deprecated, better use the
core functions:
serialize_branches()
<a moz-do-not-send="true" class="moz-txt-link-freetext" href="http://www.opensips.org/Resources/DocsCoreFcn16#toc128">http://www.opensips.org/Resources/DocsCoreFcn16#toc128</a>

which works in the same way.
