Ever need to leave someone a quick message, but you don’t really want to talk to them? It’s a risk to just call them because they could answer and then you’re stuck.
Now a new direct-to-voicemail phone service let’s you make that call without having to worry about that other person picking up.

SlyDial pitches itself as a way to avoid conversations you don’t want to have.

All you have to do is sign up for the service which is free as long as you listen to a 30-second ad. You can pay 15 cents per message to skip the ad or less with unlimited plans.
