Auto Dialer is a software for broadcasting voice message by phone. It does not require any special equipment or knowledge. All you need is just an Internet connection.
Of course, you can. Auto Dialer can make calls to landline phones, cell phones and SIP phones.
Actually, yes, but make sure you have a Skype Connect Account http://www.skype.com/intl/en-us/business/sip/overview. It is not enough to have a simple Skype account.

A phone number format depends on your VoiP service provider. Most likely, you need to use an international format(11 digit number including the area code and country code). For example: 14251235678. For some international calls you may be needed to add a prefix like 011.
Yes, it does. If a call is answered by an answering machine, Auto Dialer listens for the whole "Welcome message" and waits for the beep. And only then plays the message.
For a typical 30 second message, on average, you are looking at making 1 call per minute, and 60 calls per hour on a single line.
