Food for Thought: Yet another cool feature brought to you by BlackBerry!
I've recently purchased my first BlackBerry Smart Phone, so I've been doing a lot of research on different applications and features that are available with these Smart Phones. The feature that I thought you may find interesting is called the Mobile Voice System (MVS). Basically, it allows you to access your office phone system, and use the features that are available on your office phone right through your blackberry. This includes accessing your office voice mail, allows you to use a single phone number, and the calls you make from your blackberry can appear as if your calling from your desk. You may be wondering about the security of this application; this concern is addressed in detail on BlackBerry's website, and you can access this information, and more by clicking the link above. Also, take a look at the Blackberry forum on the message board for additional information and ideas.
Have a Great Day!
