I used freePBX 2.2.1 and it used to work well. But from about 1 month ago, i found when i entered “Panel”, all of the extensions, Trunks and parking lots keep flashing and i can’t know whether they are in use or not. Is there any suggestions on it? Thanks in advance.
I’ll bet you updated your flash player in the last month.
Flash changed a security setting for specific call and now it does not work correctly (just as you described) until you update the FOP.
If you search the FreePBX forums for flashing FOP panel you should find it. The short answer is to upgrade FreePBX and the FOP or downgrade the flash on your system.
