yes, for clarification:<br>
<br>
$var(x) = $sruid;<br>
$var(y) = $sruid;<br>
<br>
the result is that $var(x) != $var(y)<br>

<p class="MsoPlainText">Does this mean that for each request the
$sruid variable returns a new unique id or the same for each
kamailio instance?</p>
</div>
</blockquote>
<br>
For a better understanding, the value is made of several components:<br>
- server_id global parameter, only if set in config and different
than 0 (which is default value)<br>
- timestamp when kamailio is started<br>
- process id for each worker<br>
- an incremented value for each sruid (or a random value each time,
but this is not exported in config)<br>
<br>
The collision across many instances even if server_id is not set is
very unlikely. It would require that the instances are started at
the same time and the task scheduler gives the same PID values for
kamailio processes. But as said, if you have multiple instances, you
can just set different server_id values.<br>
<br>
Adding the alternative to use values generated by libuuid should not
be that hard at all, for what I needed so far, $sruid was never
colliding (and again, is very unlikely to happen anyhow).<br>
<br>
Cheers,<br>
Daniel<br>
