[OpenSIPS-Users] Load Balancer Probing Question

[Callum Guy]

If the backend servers are both the same instance then this seems to be the
correct behaviour?

I believe the probing is supposed to be a simple SIP response healthcheck
which applies to the destination globally (i.e. 1.2.3.4 is offline), the
groups are just a way of splitting up resources logically for load
balancing purposes.
