[Freeswitch-users] BLF no longer display actual registration status of phones

We have a problem in BLF indicators - disconnected phones still show as registered (solid green) in the displays. It's an Atcom AT640P phone but it worked before. FS version 1.2.13 64-bit on CentOS 6 2.6.32. How can I trace the problem? ESL, databases, etc. Thanks for any help/hint. Note: Please ignore my earlier post re "BLF Troubleshooting" because this is the real issue. /Nandy
