Hello,<br>
<br>
run with debug=3 in config file and see if there are log messages
that gives you more details about what happens.<br>
<br>
Typically, when doing replication, you may need to replicate
received and sometime socket information -- that can be done via
headers and then added to avps before saving to location in the
second peer. Look at the readme of registrar module for those
parameters.<br>
<br>

<div dir="ltr">Hi all,
<div><br>
</div>
<div>I am trying to setup an active-active pair of sip proxies.
I have connected two kamailio boxes to the same PostgreSQL
database and my usrloc db_mode is 3. I can see the
registration data in the database but "ul show" outputs of two
device is not same. I think writing registration data to the
same db is not enough. </div>
<div><br>
</div>
<div>I have found a method to replicate the registraiton
process. With t_replicate, I synchronize REGISTER requests to
both boxes. But I had to disable shared database because of
uniqe id validations.</div>

<div>My media servers randomly sends calls to SIP proxies. If
Media server send the call to the original registrar then the
replicated, call initiates normally. But when UA registered in
first proxy, and Media server sends the call to the send one,
even if second one has UA in location table, call does not
initiate.</div>
<div><br>
</div>
<div>Does anyone have an idea about this kind of an active
active setup?</div>
