The most recent released version of SER is 0.9.6, also referred to as 0.9.x. Go to iptel.org's FTP server for download of latest stable release 0.9.6. Previous version are also available. Snapshots of upcoming patch release for SER 0.9.x are also available. Patch releases contain bug and security fixes.
You probably want to have a look at the SER - Getting Started document. It will guide you stepwise through the most basic (and useful() setup and configurations of SER. You may also want to base your own configuration files on the examples. See also Get Started with SER for more information.
If you are interested in the new features for the current unstable SER, you can get the vary latest code from the repository of daily builds.
RTPProxy is used together with SER for handling media-streams (RTPi) for user agents behind NATi. The SER configuration script should use functions in the nathelper module to determine when to proxy and then call force_rtp_proxy() and unforce_rtp_proxy() to initiate and tear down audio sessions. See SER - Getting Started for how to use RTPProxy (and mediaproxy, the alternative developed in python).
The very latest development version of RTPProxy can be downloaded using the same cvs commands as described for SER above. However, use cvs co rtpproxy to check out the rtpproxy directory instead of sip_router.
The alternative to RTPProxy, mediaproxy, is not maintained on iptel.org. It's homepage is http://mediaproxy.ag-projects.com/
SEMS version 0.9.0 can be found on the iptel.org FTP server for SEMS. NOTE!! A new SEMS version has recently been made available using subversion (an alternative to CVS).

SIPSak is a very efficient tool for sending and receiving SIP messages (i.e. simulating a user agent serveri/client). It can do a whole lot of things, everything from monitoring SER by regularly sending an OPTIONS message to simulate calls. It is light-weight and reads text-files with the messages to send (with some substitution). Download SIPSak from iptel.org's FTP server (grab the latest).
