My problem is that my boss calls me every night, out of business hours, to talk about work, when I am at home, with family, or doing other things. Even a sunday early morning, the only day that I can sleep 'til late. So, I am searching for an Android app that I can block my boss incoming calls in certain days and time, like google voice. If you check on google voice, you can set up the days and times that you want to receive calls or not, sending it to the voicemail box or even to another number. Does anyone knows a such app? I am deeply appreciated in advance for recommendations.
