  The first line will allow incomming SIP traffic. The second line will
  allow incomming RTP traffic on the ports 7070 - 7080 (the default port
  range used by siproxd for incomming RTP traffic).
 
+ The rule for masquerading will ensure that the outgoing RTP data stream
+ is masqueraded properly and sent to the remote host.

+Release Notes for siproxd-0.2.2
+===============================
+ - SIP Proxy for SIP based softphones hidden behind a masquerading firewall
+ - Includes an RTP data stream proxy for *incomming* audio data
+   (outgoing RTP data should be handled by IP masquerading by the firewall)
+ - Port range to be used for incomming RTP traffic is configurable
+   (-> easy to set up apropriate firewall rules for incomming traffic)
+ - Multiple local users/hosts can be masqueraded simultaneously
+ - Supports running in a chroot jail (configurable)
+ - Supports changing user-ID after startup (if started as root)
+ - All configuration done via one simple ascii configuration file
+ - Proxy Authentication for registration of local clients (User Agents)
+   now supports per user passwords
+ - Logging to syslog in Daemon mode
+ - Access control (IP based) for incomming traffic
+ - RPM support (spec file)
+
+Requirements:
+ - pthreads
+ - libosip 0.8.8 
+
+Currently tested on Linux 2.2.x (Redhat 6.0) and 2.4.x (Redhat 7.2),
+should run on others Linux distributions as well.
