If you have the same kind of network constraints (UAC behind NAT), then
in it not work for UDP either. If the UAC is nated, in 99% of the cases,
it is able to be reached back only by the SIP node the UAC is
registering with.
So you have to re-think the internal design of your cluster.

I got your point . I understand why 477 send failed message is coming .
Lets I am not using TCP . I am using UDP . my question is how I will
use a single DB behind a cluster of opensips . Is this possible in UDP
. I dont think so . In UDP i may get "408 request timeout" message
from opensips node .
Lets say . I have a client and I have given a domain to that . against
that domain there are 2 opensips node and both sharing same DB and
running in db_only mode . My UAC is behind NAT off-course .
According to you I cant use this scenario if my UAC is behind NAT
. If opensips nodes and UAC can communicate internally inside a LAN
then its possible .
Please correct me if I am wrong .

Sasmita,
OpenSIPS can open a new TCP connection towards an UAC IF:
1) the registered IP is public
2) the UAC is not behind a NAT.
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.

Is there any way opensips nodes will be connected in TCP ? If
what I am expecting is not possible then I will leave this .
Then my question is whats the use of opensips cluster using same
DB ? In which scenarion I can use this . I just want a cluster of
opensips node sharing a single DB . How can I achieve this ?

Hi Sasmita,
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)

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