[OpenSIPS-Users] Dialog Replication in Active Active mode

[Liviu Chircu]

Hello Jai,

Looking at your active-active configuration, I must ask:
with your model, in case OSP1 goes down, how will BYEs reach OSP2 in 
order to terminate OSP1's ongoing calls?

Your conclusions are correct. Dialog replication is designed to work 
with a common virtual IP between two OpenSIPS machines.

What looks worrying is the segfault 16 seconds after processing failed. 
In order to have that figured out,
could you please post the output of "/usr/sbin/opensips -V, along with a 
gdb backtrace? [1]
