I have Avaya 9611G IP phones built in a "pod" with multiple bridged appearances on multiple phones. These are connected to an HP 5400 Poe Switch and a G450 gateway is in the same IDF. Every once in a while all the phones start exhibiting the following behaviour.
All eight LED (both green and red) flash about once a second and on the LCD screen the extensions display then go blank at the same rate. Calls cannot be sent or received. The only fix is to either unplug some of the phones or to "busy out-release" the lines. There are no log entries in our network switch or on the Avaya system. If this was a power issue I would expect the phone to reboot but this is not what is happening.
