We are running Elastix 2.0.2 with FreePBX 126.96.36.199 and Grandstream GXP-2000 phones. I have setup day night control on elastix and setup a speeddial button on all the phones so when everyone leaves someone can just push the button and set the system into night mode. But... whats happening now is someone activates night mode and then someone else re-activates day mode because nobody is saying hey i already activated night mode. So what I am wanting to do is set like a BLF function somehow on the phones that way when night mode is active the speeddial button on the grandstream phones for day/night control is lit up showing its active. Is this possible? Ive attempted to google but havent had much luck.
