Chris also wants to know why a call will ring once and then go directly to voicemail. Leo says that's an odd one and he has this happen too. Is it something the telemarketers have figured out? It could be carrier specific. Chris can sign up with the DoNotCall registry but that won't stop telemarketers from outside the country. Another option is to use Google Voice for everything, then he can program Voice to forward telemarketer calls directly to voicemail or reject them altogether.
Heath gets a lot of calls he doesn't want throughout the day. How can he block calls from people that aren't in his contact list, or send them directly to voicemail? Until recently, the FCC didn't allow carriers to do that, but carriers now have the ability to block calls. So the carrier could do this. But to block them himself, it isn't possible with an app because Apple doesn't allow alternate dialer apps. There are options for this on Android, however.
