This app disabled my voicemail and I have zero options to have it. All callers are told that my voicemail isn't set up. No options to set it up in the app either. My actual voicemail shows it should be working. Wish I read other people's comments about this issue before I bought it. And it would have been nice if the authors of the app warned people about the voicemail issue / conflict.

Very happy with this. So far, it's done exactly as advertised. I'd been having issues with a spam caller, since june, calling constantly, claiming to be a health insurance provider, and found after some research that I wasn't the only one experiencing this problem. Setup of this app has been very straightforward, and so far, they haven't called yet. Hope I've finally found the solution!

Well, for the most part it does what its says it will do. It will stop potential spam or scam calls and claims to do the same for messages. Not all messages are scanned like calls are. I only have a cple issues. One, if the number is not in your contact list and you're expecting a call back and Robo doesnt recognize it, it wont let the call through, the other is that I wish there were some more answerbot choices. Some take too long and the caller hangs up too long a pause between phrases on
