<div>Hi everyone, currently i am running 2 Asterisk Servers
that share the same dialplan and sip users, also they
connect through DUNDi. Right now i need that the users on
certain network register to one of the 2 servers and in
case it fails, then kamailio should tell the phone to log
in to the backup server. After the main server for that
location is restored the phones should connect again to
the main server.<br>
<br>
</div>
<div>something like this:<br>
<br>
</div>
Location A
Location B<br>
<br>
</div>
network: <a moz-do-not-send="true"
href="http://192.168.1.0/24">192.168.1.0/24</a>
network: <a moz-do-not-send="true"
href="http://192.168.2.0/24">192.168.2.0/24</a><br>
</div>
main asterisk server: 192.168.1.1 main asterisk
server: 192.168.2.1<br>
<div>backup asterisk server: 192.168.2.1 backup
asterisk server: 192.168.1.1<br>
<br>
<br>
</div>
<div>Unless there's a failover situation the phones on Location
A (network: <a moz-do-not-send="true"
href="http://192.168.1.0/24">192.168.1.0/24</a>) should
login to their main server, same with Location B , as soon the
problem is fixed they should failback to their main server
again, as i said both asterisk server share the same dialplan
and sip-users.<br>
<br>
</div>
<div>I don't want to let kamailio handle the user registration,
i just need it to tell the phones which asterisk server should
they contact based on their IP and main/backup server status.
I tried to do it using DNS-SRV instead of Kamalio, it worked,
but the phones never failback, also, DNS-SRV doesn't tell what
server should be used based on the network the request came
from.<br>
<br>
</div>
<div>I've been trying to do this and really need help, any
example would be appreciated, thanks in advance. Also i'd like
to know if this is possible using H.323 protocol suit instead
of SIP.<br>
</div>
</div>

Kamailio is SIP only signaling server, no h323.<br>
<br>
Now, regarding the registration, if you run Asterisk with the patch
for Path support, you can forward registration from kamailio, after
adding the Path header (see path module) to the appropriate
asterisk.<br>
<br>
To select the asterisk you can group your users with group module
(or other modules such as mtree, htable or simply in database and
use sql_query() to see which group an user belong to). Based on the
group an user belongs to, you use dispatcher module with a specific
setid. Say group 1 will use setid 1 and group 2 will use setid 2.<br>
<br>
For each setid in dispatcher, you have to store the addresses of the
two asterisk boxes, with highest priority to the asterisk that
should be used first. dispatcher can do OPTIONS keepalives to detect
when an asterisk is down and mark it as inactive until in comes back
alive.<br>
<br>
Cheers,<br>
