I will give that a go. Since the HTC One already has a call blocking feature built in, which is very good as it does not give any notification whatsoever that the call/sms has been blocked i am wondering…

a. Does Avast give any notification?

b. Does it have an answer/hangup feature or will it simply divert it to voicemail?

c. Does my handset have to be routed to use call/sms blocker?
