[OpenSIPS-Users] I have a query regarding loadbalance of opensips .

[Bogdan-Andrei Iancu]

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)

Best regards,
