Hi chaps/chapesses
Does anyone know how I Can build a "Telephone Engaged" Indicator?
I need to have some kind of indication to let me know when the kids are "On or Off" the phone or internet when they are upstairs, I don't want to run up & down stairs every 5 minutes to ask them, And I don't want to be picking up the phone to check if it's engaged, Specially if they are whispering "sweet nothings" to their loved ones,
Ideally this "Indicator" would need to be an "LED" which would come on when the phone line becomes "Engaged"
Perhaps manufacturers should put this form of "Indicator" on all of their phones
But I would be quite happy with just an LED Indicator
Can't wait for some replies
