Currently the DSS/BLF key for Ext. 100 is flashing on all phones that have this appearance.
I've gone to extension 100 checked for VM messages and cleared all message notifications. I've also reset the system as a last resort.
It still keeps on flashing.

Any help would be appreciated.

Thanks,
Al

Sounds like ext 100 has a forwarding feature set or DND.

I had this happen to me once, and I received the following, but can't remember from where. Would like to give credit where it's due. Could have been from someone here. Anyway, for some reason, when I got to the site, it had cleared up by itself. This was on a 9100.

DSS key for 100 flashes red at all phones.

Please do the following:
1) Go to 100, press the Speaker button and dial 7900100, and press the Speaker button. If that does not clear the problem, then:
2) At 100, press the Speaker button and dial 7133 and press the Speaker button. If that does not clear the problem, then:
3) From 100, press the Speaker button and dial 7470 and press the Speaker button.

Thanks Yoda,

The first code cleared the problem.
