Leave Voicemail Without Ringing the Phone
If, for one reason or another you want to leave someone a voicemail, but don't want to risk that they pick up the phone when you call, try slydial. It's pretty simple. Dial 267-slydial (267-759-3425) from your phone. When you hear the prompt, enter the number you want to call. Then, after some advertisements, you will be connected directly to the person's voicemail. It's free - but if you want to avoid the advertisements and such, you can sign up for a premium account.
