Hello.

 

I think that some sites use OpenSER with Asterisk server.

But Why?  (for accounting? or supplementary service?)

Aren't they same?

 

In conceptionally, OpenSER is central VoIP server, and Asterisk is IP-PBX for apart site.  right?

What is the structure of service being applied, in generally?

 

OpenSER, Asterisk,...

What is the role of them?

 

thank you.
