[OpenSER-Users] Openser as reverse proxy

[hdpml]

Dear Mailinglist,

I am a rookie in SER and joined this mailinglist a few minutes ago. Hope 
you can help me with my question.
I found ser at my search for a sip / rtp proxy. I want to install the 
following scenario:

client -> Internet or WLAN -> SER proxy + rtpproxy(DMZ) -> Asterisk 
(Internal LAN)

Is it possible with openser that the authentication is passed through to 
asterisk and openser accept the call if the user is valid?
My idea is, not to have any userdata on the SER proxy. I just want that 
the proxy forwards the request to the asteriskserver and checks if the 
REGISTER is OK or not. If the user is invalid, the proxy should deny 
requests from this user to the asteriskserver.
If this will be possible, is it possible to integrate encryption of RTP 
and SIP too?

Like a http reverseproxy?

Thank you very much.

Dominic
