[Serusers] SIP and SER newbie

Hello everyone. I downloaded the latest version (0.8.14) of SER and installed it on my redhat linux server. I've not set up a sip server before so I'm new to this. 1.) Would you please point me in the direction to get started in configuring the SER server? I would like to test it out w/ an ip phone and windows messenger. I've been using some of the documentation that were available at the same ftp site. 2.) I noticed that it is preferable to install and use mysql. I already have mysql installed on my server, but the file "ser-mysql" could not be found in the latest directory on the ftp site. Where can I find that file to set up mysql for SER? 3.) What ports should I have open for SER to function if I'm behind firewall? 4.) Lastly, I would also like to set up the sms gateway module. How can I have access to that module? Thank you for your help. Sher
