All night long I get internationals calls which are from a different number each time. I have to now shut the volume off my phone off so I can sleep. This is not a good idea if someone in my family is trying to reach me. I purchased the Call Filter thinking that would help but it can only block an individual call when these callers are using different numbers each time. There must be a better way than turning the volume off on my phone. I can't be woken up from these calls.
