I have a problem with my Cisco SPA504G VOIP handset.
The horizontal red light at the top of the phone comes on when I receive a message.
I want the red light to be off all the time, as I receive my messages by email.
I changed the Cisco SPA504G configuration, Voice / Ext 1 / Call Feature Settings / Message Waiting to "no".
That turned the light off, but it came on again when the next message was left.
