Busy Lamp Field issue

Note: this model has serious problems with the Busy Lamp Field feature when connected to Asterisk. The issue has not been solved by Grandstream, and applies even to the latest firmware version. Currently the only solution might involve modifying Asterisk source code and recompiling it http://forums.grandstream.com/forums/index.php?topic=1922.0.
