Want to call in sick without actually talking to the boss? MobileSphere just launched a free voice messaging service called Slydial that connects you directly to someone's voicemail so you can actually leave a message when you're pressed for time or want to avoid any awkward conversations.

Slydial is a free service that doesn't require an account unless you want extra features like Click 2 Slydial, which allows you to initiate a call from your computer. To get started, you simply dial 267-Slydial (267-759-3425) from any landline or mobile phone number, enter the cell phone number of the person you want to call, and wait for the service to connect you to their voicemail. Pretty sly, huh?

I tried the service and had no problems going staight to voicemail as advertised. You do have to endure a rather long advertisement, but if you plan to do this often, I recommend you sign up for the ad-free service which sets you back $.15 per call and includes some  rather interesting features.
