<p>Hello,</p>
<p>if you send first register to one asterisk and it replies 401,
then the following up register has to be sent to same asterisk,
otherwise the authentication fails if you send to 2nd asterisk and
it doesn't recognize the nonce, no matter the user password is the
same.</p>
<p>Maybe asterisk has options to "share" (generate and recognize
same) nonce values across different instance, if yes, be sure it
is enabled. In kamailio that is possible by setting the
appropriate parameters in auth module.</p>
<p>Cheers,<br>

<div>Hi Aristeidis,</div>
David is right, first would be good to check the
status of the destinations.<br>
<br>
In your configuration there are couple of things
to have in mind: need to set correct flag param
<br>
<a href="https://kamailio.org/docs/modules/5.5.x/modules/dispatcher.html#dispatcher.p.flags" target="_blank">https://kamailio.org/docs/modules/5.5.x/modules/dispatcher.html#dispatcher.p.flags</a><br>
select the algorithm used to select the
destination (ds_select_dst) and have a
faulure_route where the next destination will be
tried in case first is down.
<div>You can find the examples in the module
doc.
<div><br>
Cheers,<br>

<div>I have a Kamailio and 2 asterisk
servers. All users are created in both of
the asterisk servers. I am forwarding the
registration to asterisk. The problem is
that it is always used on only one server
from the list. Even if one goes to
shutdown, then there is not any
registration sent to the available server.
Even if <u><b>some </b></u>of the
extensions can be seen registered in both
of the asterisk's, if the secondary goes
down, then there are no services for the
phones. <br>
</div>
<div><br>
</div>
<div>I am attaching the kamailio.cfg. My
dispatch list is:</div>
<div>1 sip:<a href="http://192.168.0.100:5080" target="_blank">192.168.0.100:5080</a>
0 0 maxload=20<br>
2 sip:<a href="http://192.168.0.101:5080" target="_blank">192.168.0.101:5080</a>
0 0 maxload=20</div>
<div><br>
</div>
<div>In both of the asterisk servers i am
using sip.conf to create users and s sip
trunk for the Kamailio. Nothing special
about it.</div>
<div><br>

<div>I am looking to find what is wrong with
my config and i cannot
loadbalance/failover to the asterisk
servers. <br>
