One of the reasons why I love VoIP so much is its ability to unify technology and simplify my life. I've gotten used to the conveniences of getting voice mail delivered to my e-mail and being able to turn my laptop into my desk phone and work from my pajamas, but I still want more.
One of the newer features that has really spoiled me is our Firefox Click-to-Call Add-on, which allows me to dial any number listed on a web page from my configured SIP phone with a single mouse-click. Why waste time typing in a phone number? VoIP can save you the effort and you can spend your time doing what a human is really necessary for -- actually having the conversation.
Where does the Firefox Add-on become particularly useful? Any web page with numbers on it now becomes a dialing directory, which means that your Intranet with the phone directory of all of your employees is now a time-saving tool. If you use a web-based CRM, like Salesforce, calling a customer is as simple as clicking on the phone number in their account. (We like this feature a lot.) Want to order a pizza? Call a restaurant and make reservations? You're likely to go to the restaurant's web page to find the number, so why not let your computer also dial the number for you? Cell phones made it unnecessary to punch in a number years ago, so why still do it on your desk phone?
