Hello,<br>
<br>
if you want to rely on kamailio to memorize where to send the
following register, the hash table is the right tool.<br>
<br>
Cheers,<br>

<div dir="ltr">Hello,
<div>I'm learning Kamailio. My ultimate goal is to be able to
route SIP messages from User Agents to specific FS boxes.</div>
<div><br>
</div>
<div>I'm starting with routing REGISTER messages.</div>
<div>I used app_perl to randomly lookup one of the FS box's IP
Address from postgres database, then I stored the IP in avp
and then in hash. It seemed like overkill but it was the only
way I could keep the FS IP address in memory between the first
REGISTER and REGISTER with Auth.</div>
<div><br>
</div>
<div>my app_perl script sets the IP as follows:</div>
<div><br>
</div>
<div>
<div>my $sth = $dbh->prepare("SELECT ip_address FROM
host_machine WHERE is_online = true ORDER BY random() LIMIT
1");</div>
<div>$sth->execute();</div>
<div>my $host_ip_address = $sth->fetchrow();</div>
</div>
<div>Kamailio::AVP::add(10, <a class="moz-txt-link-rfc2396E" href="sip:$host_ip_address:5060">"sip:$host_ip_address:5060"</a>);<br>
</div>
<div><br>
</div>
<div>And here is my kamailio.cfg for REGISTERs</div>
<div><br>

<div>
<div>route[REGISTRAR]</div>

<div>}</div>
</div>
<div><br>
</div>
<div><br>
</div>
<div>"random_server" is the perl script to get the FS IP
address...</div>
<div>Seems crude but works... </div>
<div>I'm sure there is probably a more elegant way to do what im
trying so any advice and criticism is appreciated, thank you!</div>
