Thanks for the cross link, 2011 was a busy year to write about and 2012 is starting off just as bad.
Please everyone protect yourselves, keep the basics of:
- Change from default passwords
- Remove excess or unneeded voice mailboxes
- Only give dial-out abilities to those who really need it (a phone card is a better option)
- Monitor your phone bills for unusual activity
- Read Mark's and other blogs to keep up to date

It's amazing what a lot of people will do just to earn a quick buck. They sometimes don't care who they inconvenience. That's why it's best to be extra vigilant against scammers.

The Cisco equipment is certainly very secure, but some customers deploy it in its default configuration, which can be non-secure.
