[Serusers] Please Help....!!!! Proxy and SERWEB

Hi, I am facing a few problem, please help: 1. I have installed Serweb in my Linux server, I try to register as a new user but the data is not inserted into the database. Please advice what can this problem be and files that i can checked. And also on my system I am unable to login but using other system I am able to login into the admin and user page. 2. I have installed sipsak to see the status of the server but I am not very sure how to start it as the guide is very limited as I need to check whether the ser is up and running fine with ppl coming in. 3. Please advice whether the proxy is already residing in the SER or I need to actually installed the proxy and where can I find the proxy server? 4. I like to confirm the sip address is my username@mydomain right? *Have a nice day (",)* Regards, Shirley
