Sir I have small suggestion. Sir may we config er what'sup tone, with our clock. Say when my any what's will come it will ring between 7 am to 10 pm. And remain silent from 10 pm to 7 am in the morning. or any time of my convenience. For my few emergency no.s it's allowed to be active for 24 hours. It will be of great comfort. Now problem is few guy give what'sup at 5 a.m so I kept what'sup silent as it is disturbance to me. This idea is for what's up, SMS, email, or even a call for Bell ringing timing attached to my clock Say 7 a.m to 10 pm. Or any time which any body can config er. But at the same time to ring 24 hours for certain personal no.s. another suggestion if any body gives call twice or thrice then phone will ring.
