OpenSIPS can open a new TCP connection towards an UAC IF:<br>
1) the registered IP is public<br>
2) the UAC is not behind a NAT.<br>
<br>
The 477 reply is generated by the inability of OpenSIPS to open a
TCP connection - you can see some error messages into the logs
too.<br>

<div bgcolor="#FFFFFF" text="#000000"> <tt>Hi Sasmita,<br>
<br>
There is an incompatibility between your opensips
cluster design and your network topology. If the end
device is TCP connected to one Node, and it is not able
(due network constraints) to receive TCP connections
from any other Node, it makes no sense to share the
registration data between the OpenSIPS Nodes as only the
Node that received the registration will be able to
reach back the device (again, due network constraints)<br>
<br>
Best regards,<br>

<div dir="ltr">Hi All ,
<div> </div>
<div> I wanted to use a single DB against 2
or more registrar server .</div>
<div><br>
</div>
<div> Below is my requirement :</div>
<div><br>
</div>
<div> Opensips1 (x.x.x.x) -> DB </div>
<div> Opensips2 (x.x.x.y) -> DB</div>
<div><br>
</div>
<div> DB is in different machine and both
opensips servers are accessing the same DB .
Opensips is running on Db only mode . db_mode: 3
.</div>
<div><br>
</div>
<div><br>
</div>
<div>I had mapped a domain in route53 ex. " <a href="http://loadbalance.i3clogic.com" target="_blank">loadbalance.i3clogic.com</a>
" and against this domain I have added both the
IPs of opensips1 and 2 as SRV .</div>
<div><br>
</div>
<div> I have added this domain in my
opensips config file as aslias in both the
config files .</div>
<div><br>
</div>
<div> what my client do is , it does SRV
query in the domain and resolve 1 Ip at a time
and send requests to that . </div>
<div><br>
</div>
<div>example :</div>
<div>A-> SRV query( resolve Ip opensips1)
-> sent Register Opensips1 -> store in DB</div>
<div> This can change in ttl expire or in
re-login of A . A is making TCP connection with
opensips .</div>
<div><br>
</div>
<div>when an Invite comes for A to opensips2 ,
that send 477 send fail . </div>
<div><br>
</div>
<div>B -> Inv (TCP connection for A )
Opensips2 </div>
<div><br>
</div>
<div> Opensips2 replys with 477 send fail to
B . The reason behind this is A is registered
through Opensips1 .</div>
<div><br>
</div>
<div>This is what I want and the problem I am
facing . My questing is how can I solve this . I
dont want to add any proxy in between client and
opensips1/2 . Is there any way this will work
for me ?</div>
