I am totally new at SER although I understand asterisk and SIP.

I installed and started 1.0.1 on a x86_64 box running fed core 4.

eventually I want to do    asterisk <----> SER <----> Phone  for load 
balancing and NAT traversal benefits.

right now I just want to know some basic things:
1. how do you know the server is really runnig
2. is there an web interface for managing and seeing the server's status.
3. how do you simply register two phones so one can call the other
4. is there some simple documentation that explains how the SER works so as 
to help you write scripts

thanks
