[OpenSIPS-Users] Topology Hiding Usage Question

[Nathaniel L. Keeling III]

Bogdan,

Thanks for explaining the purpose. I am still trying to understand the 
actual purposes and difference between SIP trunks, gateways and proxies 
and their usages. I was watching the video on Opensips as an Edge Proxy 
and was trying to implement the solution with topology hiding. I was 
also wondering, what kind of functions would the Core Engine perform 
that is not done in the edge proxy?

Thanks

Nathaniel
