Vonage integration into Outlook
 

http://www.hollsco.com/VonageOutlook

VonageOutlook is an easy-to-use application that allows you to dial
automatically from your Vonage (US) VOIP telephone from within Outlook.
Without having to read the tiny numbers, without even dialing the phone, you
can call anyone within your Outlook contact list in under two seconds with a
single mouse click!

VonageOutlook is quick, easy and intuitive: Simply right-click on the
contact you want to dial and select "Dial with Vonage". The dialer screen
will pop up, listing up to ten phone numbers associated with that contact.
Click the number you want, and your Vonage phone will ring instantly! Pick
it up, and you'll hear the other end ringing - the number you just clicked.
It's that simple!
