[OpenSIPS-Users] Topology Hiding Usage Question

[Bogdan-Andrei Iancu]

Hi Nathaniel,

The actual routing between end point (user, gateways, etc) ? Typically 
an Edge Server is dealing with low level jobs, like network or security 
level. But it is not so smart to actually implement the service logic -> 
that's done by Core Servers.
