[Spce-user] audio/video stream data through server

[yanzs]

thanks, Daniel

I spend a few days studying concepts like RTP, SIP and VOIP.

So if I disable 'rtpproxy', RTP stream can be sent directly between 
endpoints (or at least without any intermediate server I owned), it that 
correct? I am concerned with that because many concurrent video calls 
would require a high bandwidth on the server, and that is a bit expensive.

*And another question*, in the "Platform Architecture" chapter of SPCE 
handbook, it says " The mediaproxy configuration file is 
/etc/ngcp-config/templates/etc/default/ngcp-mediaproxy-ng-daemon" which 
I believe is where I can disable rtpproxy. But I could not find that 
"ngcp-mediaproxy-ng-daemon" path with spce 3.4.2 installed by virtual 
box image, do I need to install spce using NGCP install CD to get this 
ngcp-mediaproxy-ng-daemon service ?

Thanks in advance.
